The Best Nano Reef Tanks | 2019 Comparison (Updated)

Reef tank aquariums can be expensive to setup and difficult to maintain. Nano reef aquariums are a great lower cost solution, allowing you to keep corals and anemones in smaller tanks. Nano reefs have become popular the last decade and the technology available has rapidly improved and become more affordable. The best nano reef tanks won’t break the bank and will have the best coral keeping tech available.

There’s something eye catching about a nano reef filled with coral of various colors, shapes and sizes. They’re fascinating and relaxing to watch. But if you’re considering getting a nano reef aquarium, there are a few things to consider first.

When housing coral you will generally want to buy a filter, a protein skimmer, and a circulating pump or wave maker. Coral need regular water flow and movement in order to get their nutrients, it is important to avoid having a stagnant tank.

Although not essential, setting up an eco-system in addition to your coral will provide you with great some great benefits. This would involve other inhabitants like reef safe-fish, cleaning crew (crustaceans and sea-stars) and seaweed (or macro-algae). Cleaners will reduce detriment and macro algae in a refugium can help lower nitrates. Low nitrates are necessary for long term coral health. Along with your reef inhabitants you will need to find lighting to help your coral grow. This is dependent on the type of coral you wish to keep. For most species, the all in one solutions (AIO) below will have sufficient lighting.

It is important to understand your end goal requirements before purchasing your nano reef tank. Ask yourself the important questions. What type of coral do you wish to keep? Do I want fish? Do I want a sump? Do I have space for a refugium?

In order to help you find the perfect reef tank, we’ve put together a list of the top 10 tanks for 2019 specifically made for coral enthusiasts like you. Keep reading to see a list of our favourite reef tanks along with information about their price, quality, and features.

The Top 10 Best Nano Reef Tanks 2019

The Innovative Marine Fusion Peninsula 20 NUVO

Top Pick for Customization
Innovative Marine 20 gallon on kitchen counter
Innovative Marine 20 gallon on kitchen counter

This is one of our favourite tanks of 2019. It is slightly more expensive than other all-in-one aquariums on this list but it delivers great value. The rimless design of this marine nano gives it an edge over the competition. In our opinion, rimless is essential in 2019 (It’s just too beautiful!). A perfect addition to those who want clownfish on the kitchen counter or in their bedroom.

One of the main reasons we have listed this tank as #1 is its customisability. For such a small aquarium, Innovative Marine has done an excellent job in allowing the user to create the tank of their dreams. The filter sock can be subbed out for 3 levels of bio-media. There is a second chamber that can either be used as a refugium or fits a skimmer. The final chamber allows enough room for your heater and ATO to keep all the wires covered.


  • The Aquarium is rimless and looks stunning in any house location
  • The aquarium is large at 20 gallons but not too large to be placed on any flat surface or sturdy furniture. A great size for the beginner or experienced aquarist.
  • Incredible customisability options. You can easily turn the central chamber into a refugium or add in a skimmer. These are beneficial to the health of your corals.


  • The aquarium does not come with light or accessories – thats reasonably expensive at $250+
  • Open top is not appropriate for all fish. Wrasse’s are a good example of species that need mesh or closed top.

Which size and price is right for me?

The tanks we’ve listed here all range in price, size, and quality. We feel that there is something for everyone on this list, but if you need any further guidance, make sure to let us know below.

Before purchasing a tank, make sure to go over a few things in order to make the most out of your purchase. First off, decide what size is best for you since reef aquariums can range in sizes of 5 to 30 gallons (despite having the word “nano” in their name.) You also want to pay attention to whether the tank is made out of acrylic or glass. Although acrylic tanks are more durable, they don’t always look the best and they tend to scratch very easily.

If your tank comes with accessories, especially LED lights, pumps, and filters, this might hike up the price. In these cases, you may end up saving money buying a reef kit rather than purchasing all the accessories separately. An additional pump or wave maker is recommended, especially if you are planning on keeping SPS or hard corals. As we previously mentioned, moving water allows coral to get its nutrients so if the tank your purchasing already comes with a pumps, you’ve made a very wise purchase.

Should I focus on the warranty?

Products with a warranty are always a plus, but in the end, you want to buy a reef tank that is made out of high quality materials. Your inhabitants in the tank will likely be more expensive than the glass box itself! A good cautionary note to keep in mind. Coral can live for a very long time, so you want to find something that will be able to house it for the long term.

Reef tanks are a captivating and beautiful addition to one’s home. They can even help reduce stress after a long day’s work and they’re known give off an excellent feeling of tranquility to your living room, office, or bedroom. Whether  you decide to have a simple coral tank or a coral tank with fish and plants added on, what’s important is that you make the tank your own.
