DMCA.com Protection Status

Nano reef tanks are a great alternative to large coral reef tanks. With a bit of proper maintenance, you can have a similar aesthetic experience. If you’re looking for the best nano reef tanks money can buy, you might want to know all the tiny information that matters.

Nano reef tanks have been celebrated for a long time by both hobbyists and enthusiasts. Nothing beats a calm relaxing view of a reef tank in your living room, right? There are many who go for full-fledged coral reef tanks. But a similar experience can be replicated in a tinier form.

In this write-up, we’re going to discuss all there is to know about nano reef tanks. I’ve made your work easy by selecting the best ones in the marketplace, according to my book.

So, if you’re looking for the best nano reef tanks money can buy, you’ve come to the right place. I’ll guide you through the tide of information that not only will resolve your problems but give you a general idea about the whole deal.

So, why wait? Let’s dive in!

Categorizing Salt Water Tanks

Despite this article being about nano reef tanks, you need to know what kind of hobby you’re getting into. It all might seem to be a handful at first, but we’re here to make things easy. Let’s talk about the basics.

The first thing you want to do before getting a saltwater tank is to decide on the size. Then, of course, you need to plan on the inhabitants of your tank. Then comes the equipment, and lastly, the aquarium type. Trust me; there’s more to this than the saltwater vs. freshwater debate.

While freshwater tanks can be of various kinds like tropical, biotope, cold water tanks, and so on, saltwater tanks can be of three types in specific. Hold on to your life jackets; we’re about to sail through the details.

Fish Only Tanks

The best fish-only tanks are possibly the simplest ones. These tanks are the cheapest saltwater tanks by far. Maintaining this type of aquarium might seem like a breeze. But you should note that maintaining the nitrogen cycle is vital since you don’t need equipment to maintain corals and live rocks.

It might get messy if the bacteria inside the tank can’t break down the toxins like ammonia into substances that cause less harm. It takes way more time in fish-only tanks to establish the nitrogen cycle than in FOWLR or basic reef tanks.

A frequent check of water changes is required for these tanks in specific. You might want to get the best aquarium water test possible for these fish-only tanks. This is mainly for keeping a sharp eye on pesky ammonia, nitrate, nitrite, and pH levels.

Fish-only tanks can also be divided into community and semi-aggressive tanks. Look it up for more details.

FOWLR (Fish Only with Live Rock) Tanks

Before we start, I need you to know that the fundamental difference between fish-only tanks and FOWLR tanks is the presence of live rocks. The term is given by aquarium hobbyists that signify rock formations that house various algae and other organisms.

These live rocks and their organisms are great for saltwater tanks as they serve as natural water filtration units. The ratio of live rocks in saltwater tanks should be 1-2 lbs per gallon. Sound expensive? Well, it really is!

You can choose to cure your own live rocks without buying them. But that’s a whole different kind of hassle, to be honest.

In these types of tanks, the larger the size, the better. Smaller tanks may cause chemical imbalances that might prove to be fatal. You might want to get the best type of saltwater aquarium filters out there. Yes, I’m talking about stuff like the Penn-Plax Cascade Canister Aquarium Filter (700 Elite).

I’d also suggest the best protein skimmers you can find in the market. Skimmers like the Csm2020-csmfr3-184 from ‎IOAOI can do the job just fine. Remember, the best filtration solutions for FOWLR tanks are the wet/dry ones or the ones with sump systems.

I’d also suggest the very best saltwater aquarium lights you can buy. I’d personally suggest the ones like the Eco Marine Tech RADION G5 LED Lighting PRO RADION XR30 G5. These are premium-grade products that won’t disappoint in any way.

1-2 watts of light is recommended per gallon. But you can do a bit of personal tweaking yourself if you want. Oh, and it’s always a great idea to start with the least aggressive species. Practice makes perfect, I always say.

The Nano Tank

We all knew this one was coming. Since this article is about the best nano reef tanks in the end, this type of tank is often used to cultivate traditional saltwater inhabitants. They, in turn, serve to become miniature reef environment units. We’ll talk about that bit later on.

You should know that due to the limited water volume of these particular types of tanks, they become rather difficult to maintain. Looking at the water parameters, analyzing the condition of the inhabitants, monitoring fish growth, and so on can be a lot of work.

Remember that you want the corals to grow slowly, and the fish should remain within the size of 2-3 inches max.

Before you decide on purchasing any nano reef tank, you should be well prepared. Proper planning can really go a long way.

Defining a Nano Reef

Before discussing the overall benefits of a nano reef tank, we need to know exactly what it is. Hobbyists tend to divide it into two categories.

Nano Reef Tank

Nano reef tanks are relatively small in size. If we go to pinpoint accuracy, these tanks don’t usually go beyond 30 gallons. You’d commonly find a small number of specific corals and invertebrates, including perhaps a few tiny fish. Remember that the best part about it is, they’re easy to take care of.

Pico Reef Tank

Well, as the name suggests, these tanks are even smaller in size. By small, I mean to say five gallons or less. The problem with these tanks is that they’re not very easy to maintain. If you want them to keep looking good, you might have to break a sweat. Plus, you need to do regular maintenance.

The Best Nano Reef Tanks Available

In-depth reviews:

Well, we’ve covered the basics of what a nano reef tank is. Now, the time has come to discuss the very best ones for you. I’ve done my research and handpicked the very best ones I could find. Without further ado, let’s begin!

1. Coralife LED Biocube Aquarium LED

Coralife LED Biocube Aquarium LED_ The Best Nano Reef Tank

The very first nano reef tank in this list is the LED Biocube Aquarium LED from Coralife. Coralife is a trusted place for advanced aquatic hobbyists. This brand is well known for its inclusive BioCube aquariums, and the particular tank we’re going to discuss is now nothing less than their best ones.

Without any doubt, this nano reef tank is one of the premium quality tanks at the price range. And why wouldn’t it be? The features, essential nano reef tank tools, and the practical design have carved the ‘top notch’ seal at the beginning of this tank’s name. Let’s dive into the details!

This almost square-shaped nano reef tank comes in the dimensions of 27.5 x 25.5 x 27 inches and weighs only 62 pounds. The weight and the dimensions are pretty much the standards. It’s quite easy to manage a little space for your hobby (read ‘this tank’) no matter how big or small your living space is.

The sleek and rounded-edged glass design is innovative and gives it a premium look. Having an aquarium serves the ultimate purpose of our hobby; however, there is another positive aspect that exists. It’s because aquariums are also excellent home decor equipment, isn’t it?

And when it comes to that, trust me, this Coralife LED Biocube Aquarium LED nano reef tank doesn’t fall behind!

The hinged top hood of this tank makes it easier for you to supply food and other vital things such as chemicals, rocks, sand, etc. Along with having all the necessary lights conveniently attached to it, this aquarium hood also ensures that the lights fill in the water correctly.

And of course, it goes without saying how efficiently this lid makes sure that the cords and lighting equipment don’t ruin the view.

The 24-hour timer attached to the hinged top hood is another innovative attachment to this premium fish tank. Having this makes it easier to control the light channels. This timer allows you to give the establishment another artificially implanted natural feature. Let me tell you how!

As I just mentioned, the Coralife LED Biocube Aquarium LED tank has three light channels. The bright white LEDs create the daytime environment of an aquatic system. This helps the corals and live plants of an aquarium to grow properly and healthily.

On the other hand, the sparkling blue light glows to make it look like nighttime. In case you didn’t know, change of lights influences the behavior of fishes, and thus it’s essential for their proper growth. With the help of the 24-hour timer, these lights make sure of it.

Then again, the color-enhancing LEDs ensure the maximum beauty of your aquarium. Trust me when I say this, looking at your aquarium at night (with the color-enhancing LEDs on) hits you differently! On top of that, there’s an automatic 60-minute moonrise/moonset and 30-minute sunrise/sunset function in it.

There’s also a compact chamber at the back of this tank. This backwall filtration chamber gives you the opportunity to store the necessary biological, mechanical, and chemical media. The submersible pump, adjustable return nozzles & dual intakes responsible for the essential water flow are also attached there.


  • Has sleek and convenient design
  • Compatible with all BioCube accessories
  • Comes in both 16 and 32 size


  • Doesn’t have an aquarium stand
  • Equipment chamber is a bit small

2. GloFish Aquarium Kit Fish Tank with LED Lighting and Filtration Included

GloFish Aquarium Kit Fish Tank with LED Lighting and Filtration Included- The Best nano reef tank

Those of you who are into fluorescent fishes must have heard the name of Glofish, more or less. Glofish is a trademark brand that manufactures aquariums to cater to your needs of making an eye-catching vibrant fish tank. And guess what, the Glofish Aquarium Kit Fish Tank might just be the right one for this job.

I’ve already said that an aquarium has a significant role in making your living space more vibrant with its home decor aspect. But you will probably be in the dark about the level of that significance if I don’t introduce you to this nano fish tank. That’s right; I’m vouching for that much for it.

The dimensions of this fish tank are 24. 2″ x 12. 4″ x 16. 7″ respectively in length, width, and height. This compact aquarium kit fish tank comes in a sleek design and weighs only 15.6 Kilograms. That’s why this fish tank is considerably lightweight compared to the other ones and doesn’t occupy much space.

The glass build of this aquarium is what you call reliable & standard when it comes to durability. In many fish tanks, the clarity of the glass wears out after a few months. You wouldn’t want that to happen to your aquarium, right? That’s why the people at GloFish have provided USA-made scratch-resistant glass.

The 13-inch long GloFish(R) LED Light Stick is attached by the LED hood. It’s a blue LED light that’s necessary for the decor items and the fishes in the tank to fluoresce vibrantly. The top lid is conveniently thick enough to hold the light inside the tank.

Instead of being horizontally attached to the aquarium roof, the LED light in this fish tank is attached vertically. So, the light goes right inside the water and ensures optimal light reaches every corner of the tank. And don’t worry, it’s entirely safe for your fish and live plants.

Bundled together with the 20 Gallon Glass Aquarium and one LED hood, there’s a Tetra Mini UL Heater in the Glofish Aquarium Kit Fish Tank. This mini heater helps you maintain the optimal temperature for the proper growth of your fish. Like you and me, fishes are also sensitive to temperature change.

There’s also a Tetra Whisper 20 cartridge filter inside the kit box. It’s essential to maintain optimal conditions for the fish tank. This filter takes care of the excess food, free-floating particle issues. It also removes the decaying organic matter, waste products of fishes, and toxic chemicals.

Make sure that you change this filter cartridge once every month to get the best results. While changing it, you should also change 25% of the water with dechlorinated water. I’d suggest you to use effective ones like the GloFish Water Conditioner for this particular job.

Altogether, this one here is the complete package for any aquarist. It’s also the top-rated nano reef tank in the list.


  • Has 3 stage filtration system
  • Quality build
  • Easy to assemble
  • Great for home decor


  • Less variety of lights (no white light)

3. MarineLand Contour Glass Aquarium Kit with Rail Light

MarineLand Contour Glass Aquarium Kit with Rail Light

The next one on our list of the best nano reef tanks is the MarineLand Contour Glass Aquarium Kit with Rail Light. MarineLand is a reputed name in the aquarium industry and has been here for more than four decades. They have made their name by manufacturing innovative and quality products.

If you’re a little short on budget but looking for a quality fish tank, then this one is your go-to model. The people at MarineLand prioritize the needs of their customers. And being considerate about the fact that owning & maintaining a fish tank is usually expensive, they have introduced this model to us.

MarineLand Contour Glass Aquarium is an 8 pounds lightweight fish tank with 9.5 x 10 x 10 inches ( L x W x H) dimensions. This aquarium is one of the lightest among all the other ones on this list. The compact size and weight make it convenient to keep it on your office desk or home.

From my experience, having a setup like this at your workplace can really help you to get rid of the monotonous cycle. I guess you all can agree with me on this one. I mean, the vibrant course of life in a fish tank is meant to do that, right?

This square-shaped aquarium comes with a sleek and compact design. The round cornered glasses in this tank ensure that your view doesn’t get interrupted from any angle. This tank structure is made of quality glass, ensuring a long and durable life span with an anticipated clear view.

The sliding glass canopy and the hinged light in this structure are innovative touches to this whole thing. Because this simple yet practical modification alone saves a couple of bucks for you, this canopy design allows you to access the aquarium easily and makes sure that the light can reach the bottom.

Speaking of the lights, this aquarium kit has two, the bright LED light and the blue LED light. These two types of lights respectively create an aquatic day and night environment in your aquarium. Besides helping the fishes to grow well, these lights allow you to enjoy different views of the setup. 

This aquarium kit creates a barrier against the harmful elements using the 3 stage filtration method. These three stages are mechanical filtration, chemical filtration, and biological filtration. Through these filtrations, the debris, odors and impurities get removed, and toxic ammonia & nitrite gets eliminated.

You’ll also get a flow filter tank that can be adjusted according to your convenience.

The MarineLand Contour Glass Aquarium Kit with Rail Light is definitely the best value for money. It’d be hard to get a quality fish tank like this at this price range. MarineLand surely had to cut a few corners to make this budget-friendly, but it has almost all the essential equipment which is necessary for a fish tank.


  • Comes in an affordable price range
  • best value for the money
  • 3 stage filtration system
  • Practical Design


  • Doesn’t have an equipment chamber

4. Fluval SPEC Freshwater Aquarium Kit

Fluval SPEC Freshwater Aquarium Kit

What we have here next is the Fluval SPEC Freshwater Aquarium Kit. As far as its reputation goes, Fluval is known for setting the bar in quality with their innovation and technology. In case you don’t know, Fluval was the first to introduce the 3-stage filter with synchronous motor technology that we see today.

If you’re looking for a small tank at your home or office, this Fluval SPEC Freshwater Aquarium Kit will be your perfect choice. It’ll only occupy a tiny place, but its existence will make your daily life more vivid with its perks. That’s something I can definitely vouch for.

Now the question is, ‘is it worth buying?’ Let me answer that for you!

Having 8.2 inches length, 21.4 inches width and 12.5 inches height, Fluval SPEC Freshwater Aquarium Kit is the smallest and the most compact of all. On top of that, this contemporary aquarium kit weighs only 5 kg in total. That also makes it the most lightweight aquarium on the list.

If you’re someone who has one or two pet fishes and likes to keep them around, then this model will be the most practical choice for you. Because of the convenient weight and size, you can easily carry it to your office and take it back with you. The same goes when you’re planning on going somewhere else.

This comes in quite handy for a couple of reasons. First of all, aquariums need high maintenance, especially the small ones. You can’t just leave them unattended for a long time. Secondly, it’s necessary to supply food to fish 2/3 times a day. You can’t always rely on your neighbor for that, can you?

Even if it comes to that, this Fluval SPEC Freshwater Aquarium Kit has the upper hand here. Why? The answer is easy. If you own a large aquarium, then it’s really troublesome to move them every now and then. Also, it’s actually a lot to ask your neighbors to take care of the aquarium at your house.

However, this compact design and weight allow you to leave the full kit at your friend’s or neighbor’s place if you’re leaving the house for a couple of days. You also don’t have to worry much about maintenance issues. Change the filter and adjust other things; it will be suitable for 3 weeks at least. 

Speaking of the filter, this aquarium kit has a powerful 3-stage filtration system that ensures the superior quality of water with the help of foam, carbon, and biomax insert. There’s also a circulation pump with output nozzle and a low-voltage transformer. These are also dedicated to maintaining water quality.

Next comes the overhanging high-output and energy-efficient 7000K LED. It consists of 37 small yet powerful LED lights. The light of this LED setup is usually 20% brighter than the other aquariums. It helps the fishes and live plants to grow properly.  


  • Equipment is located in the back chamber and not visible
  • Has sufficient light
  • Easy to carry and change places
  • Occupies a very little space


  • Might seem a little ‘high maintenance’

5. Marina LED Aquarium Kit

Marina LED Aquarium Kit- Nano Reef Tank

The Marina LED Aquarium Kit is the next one to claim its position in this list. Marina is a sub-brand of the popular pet products manufacturing brand Hagen Group. Hagen Group has taken pet care products and services to a whole new level. They have successfully been in service for more than six decades now.

Now the question is, is this Marina LED Aquarium Kit worthy enough to be the best nano reef tank? I guess we’ll have to find that out!

Let’s focus on its build first. The aquarium tank of this kit is made of durable and scratch-free glass. The ergonomic shape and finishing give it a sleek look. The borderline at the bottom and the top is plastic-covered. Besides having a style aspect, it also prevents getting any scratches on the surface.

The dimensions of this tank are 24 x 12.5 x 16.5 inches ( L x W x H). This tank is designed to hold 20 U.S. gallons or 75 liters of water. The 35 pounds weight of this structure is a standard weight. Still, if you want to move this aquarium, then I suggest you do it when it’s empty. Or else it’ll be pretty heavy to carry. 

This structure is covered with a hinged top hood that ensures easy access to the whole fish tank. It’s a convenient design that allows you to supply food, chemicals, and other elements without any trouble. Then again, the hood is also thick enough to keep sufficient light inside the fish tank.

Speaking of lights, the LED light of the Marina LED Aquarium Kit is horizontally attached to the hinged top hood. The bright LED white light is essential for the fish and live plants of the aquarium to grow well. This natural daylight effect also makes the fishes more active as it’s in their nature.

As you know already, the fish tanks tend to produce a lot of floating debris, pollutants, odors, toxic ammonia, and many other dangerous elements. If you don’t take care of this on a basis, then the environment of the fish tank will gradually become unsuitable for the inhabitants.

To prevent such situations, the Marina LED Aquarium Kit comes with a Marina Slim S20 clip-on filter with quick-change filter cartridges. This filter cartridge thoroughly cleans and removes all the pollutants and toxic elements. BTW, for best results, you should change the filter cartridge once every month.

The Marina LED Aquarium Kit is called the ideal one for a beginner-level aquarium hobbyist. Because it’s the complete package for anyone who wants to start their own aquarium. For proper growth and health, this kit has Fluval Max fish food. Fluval Aqua Plus Water Conditioner ensures safe water for your fish.

Also, this kit has Biologica Supplement, which creates a biologically balanced environment in your fish tank. The care guide book contains all the necessary instructions on maintaining your aquarium properly. To protect the fins of the fishes, this kit also offers Fishnet made from soft mesh.


  • It’s a complete aquarium kit
  • Ideal for beginners
  • Reasonable Price


  • There’s no water circulation pump

6. Fluval Sea Flex Saltwater Aquarium Kit (32.5 US gal)

Fluval Sea Flex Saltwater Aquarium Kit (32.5 US gal)

The previous one from Fluval was a dedicated freshwater aquarium, and this one here is a dedicated saltwater aquarium kit. Let’s find out the details of this kit and see what’s different.

The Fluval Sea Flex Saltwater Aquarium Kit is the most advanced technology-based premium quality nano reef tank. The features, technology, compatibility, design, and everything else stand out among the other ones on this list. And, of course, this kit comes a bit pricey.

All the materials of this structure are of high quality. From the glass build to the top hood, each of them gives an assurance of durability and premiumness. The scratch-free glass will make sure that you can enjoy a clear view of your precious fishes and corals for a long time.

This saltwater aquarium kit has a standard 22.11 kg weight, and the dimensions are 32.28 x 15.75 x 15.35 inches in length, width, and height. Compared to the other aquariums of this size, this particular one from Fluval is definitely lightweight and easy to move from one place to another.

The Marine 3.0 LED light of this kit can be controlled from your mobile phone using the FluvalSmart App. There are 3 pre-set lighting conditions: sunny reef, color boost, and deep-sea glow. So, you can simply change in between the lights from any corner of your room and enjoy the different views of the tank.

Apart from that, the lighting creates a 25000 K color temperature which is optimal for the growth of the inhabitants there. With proper lighting like this, the corals acquire the anticipated vibrant aura. BTW, there’s an optional space for another Marine 3.0 LED in case you want to attach another one.

Like the Coralife LED Biocube Aquarium LED, this Fluval Sea Flex Saltwater Aquarium Kit also has a 24-hour timer to control the mimicking of day and night. You can program the clock according to your convenience. This timer allows you to enjoy the different aquatic views with the sun and the moon. 

 For superior water quality, along with the 3-stage powerful filtration system, there are also two independent media chambers. Then again, you can create customized water flow using the two adjustable output nozzles. That’s not all; there is more!

For advanced and effective filtration, this aquarium kit has chemical (carbon), 2 oversized mechanical (foam), and biological (Biomax) media inserted in it. Usually, all the other aquarium fish tanks have only one for each purpose. On top of that, the quality is far less than this one.

You can also avail of the separately sold Fluval PS1 Protein Skimmer and M-150W Heater for your setup if you feel necessary.


  • Advanced technology and features

7. Hagen Fluval Spec V Aquarium Kit (16 gal)

Hagen Fluval Spec V Aquarium Kit (16 gal)- Nano Reef Tank

At the very end of this list, we have the Hagen Fluval Spec V Aquarium Kit. Like Marina, Hagen is also the mother brand of Fluval. The question right now is, what kind of features and advantages does this particular aquarium kit offer? Let’s dive deep into the details to find out the answer.

Each of the aquarium kits in this list has been chosen for a certain reason. Compared to the other ones of the same type, these are best of all. Each of them has different perks, and they stand out from each other in different aspects. The same thing goes for this Hagen Fluval Spec V Aquarium Kit.

It’s a rectangular-shaped aquarium with dimensions of 11.42 length, 22.05 inches width, and 17.72 inches height. Because of the compact design, the weight of this structure is conveniently less than usual. You can easily carry this 12.1 kg structure by the bottom surface and in between your arms.

The design of this fish tank is very simple and elegant at the same time. The durable glass and top hood ensure a long life span for this fish tank. At the bottom of the glass body, there’s an extra layer that protects the surface of the tank from any unexpected damage.

It’s a 16 U.S. gallon aquarium that is designed for a set up to 60 liters. You can do all kinds of stuff with this aquarium. From fish and live plants to fluorescent fishes and corals, this aquarium is standard for all of that. If you can’t decide on which one to get then, you can safely go for this one.

The kit offers 16W 7000 K high-output of LED, providing the necessary light and heat into the system. The LED light body consists of 31 small LEDs and altogether, they produce 1272 lumens into the system. The white lights mimic the daylight, and the blue lights mimic the night.

This heat and light produced here are essential for the proper growth of your plant and to bring out the vibrant color in your fishes and corals. For maintaining the water quality, this kit has an efficient 3 stage filtration system with oversized equipment.

In the mechanical filtration process, the dirt and debris get screened out by the filter cartridge floss. It also ensures a maximum amount of contact between water and carbon. The odors and impurities get removed through the chemical filtration stage by the activated carbon.

Then comes the biological filtration process. The toxic nitrite and ammonia get eliminated from the system during this process. This is done by the oversized Biomax attached inside the hidden chamber of this aquarium. There are also two adjustable nozzles at the back to redirect water flow.


  • It’s a complete package
  • Best deal for the price
  • Has good water quality maintaining features


  • Light might seem a little insufficient

How To Properly Maintain a Nano Reef Tank

These babies are pretty darn hard to maintain, as I’ve said before. Have no fear! I’ll guide you through it all the way. If you keep specific parameters in check, you should be just fine. Follow the steps I’m about to describe in detail.

The Basic Maintenance

The very first thing you might want to keep in mind is observing the need to perform water changes. You should change the water of nano reef tanks per day if you want to play safe. You have to do this to keep a stable level of pH level and salinity.

DON’T allow the water to evaporate before the next top-up. This will affect the general water chemistry and interfere with coral growth.

Waste Removal is a Must

This is probably the easiest bit of the maintenance series. This is also done in larger aquariums. All you have to do is remove all waste products from the tank to ensure there’s nothing unwanted remaining. Stirring the substrate below might also be a great idea.

Next, you have to siphon every visible debris out of the tank and if possible, perform a slight change of water.

A good water filter inside the tank will ensure the purity of the water and remove the remaining dirt particles completely. You will be more clear watching the below video.

Checking The Pump and Temperatures Help

Water conditions change really fast in small tanks. Preventing problems beforehand will save you a lot of time and energy. Not to mention resources. It’s a good idea to check the pump condition and regularly monitor the water temps to avoid mishaps. It’s a bit of a hassle, but it’s definitely worth it.

The Right Use OF Supplements

This maintenance bit is rather critical. It requires you to understand the entire water capacity of the nano reef tank. Say, if the water capacity is of five gallons, you added a few live rocks in the ecosystem. This might reduce the water a bit. Let’s say, four gallons. You need to understand this.

Not only that, but you also should have the equipment to measure the levels of K.H., pH, Calcium, Nitrite, ammonia, and Nitrate. As soon as you find a change in the waters, you can immediately apply remedial actions. Follow these essential tips, and you should get the gist of it in no time.

Feeding The Coral is Vital

You must know that the corals inside your tank also need feeding. They need to be provided with food at least twice a week. You should just turn off the pumps and give the corals about half an hour to feed.

While some corals are happy to feed on krill or mussels, some actually extend their tentacles to sting other corals or other invertebrates inside the tank. Yikes!

Once the feeding time is up, just turn on the pump again. That’s pretty much it.

Nano Reef Tank Inhabitants

Before we draw a close to this long yet informative read, let’s make a small list of nano reef tank inhabitants you can consider keeping. Here goes!

  • Live rocks
  • Small fish (2-3 inches).
  • Live sand.
  • Corals.
  • Other marine tank invertebrates (small crabs, snails, starfish etc.).


Even though I believe we’ve covered all the important stuff, there might be some flowing questions inside among us. Let’s answer the most prominent ones, shall we?

Are nano reef tanks hard to keep?

Ans: Well, technically no. But the answer remains in the patience and commitment of the owner. To sustain a nano reef tank, the tasks you need to perform are pretty straightforward. But some might find it repetitive and mundane.

Are nano reef tanks good for beginners?

Ans: The all-in-one nano reef tanks are really beginner-friendly. I wouldn’t vouch for the custom-made ones. But with a bit of dedication and care, nano reef tanks can be great for those who are starting out.

Do nano reef tanks need protein skimmers?

Ans: You can do without skimmers. But that will significantly increase your maintenance hassle. You might need to change the water more often than usual. However, if you are going for skimmers, I’d suggest you do some digging on the best protein skimmers available. Also, you will read how it works here.

A Nano Finish

Many prefer to have multiple ones in the same room as far as nano reef tanks go. They offer an incredible aquatic view while consuming far less space than the usual coral reef tanks that we are used to seeing. Each type of saltwater tank has its own set of benefits and drawbacks.

I hope you can pick one from the list that I provided. My sole purpose was to help you out in your nano reef tank venture. With that said, I think it’s time to close this one up.

Farewell! Let’s talk about some other topic next time.
