What to Look for When Buying a Nano Reef Tank


Of course, it would be nonsense to pick whatever nano reef tank you may encounter in local specialty fish or pet stores or in Amazon. There are some valuable buying guides to contemplate on before you make the final buying decision.

What are the substantial factors that you need to check out before getting a nano reef tank?

  • The components of the nano reef tank kit.

Nearly all nano reef tanks come as kits and contain various parts that serve as accessories to the aquarium. These components are vital since they assist you operate the fish tank and lessen the costs that you’d have managed by purchasing them as extras.

When getting one, see to it that the kit contains premium quality LED lighting, a filtration system and a timer or remote control to regulate the lighting. Other options include a heater which makes them more practical to purchase.

  • Outstanding filtration system.

Even though a lot of nano reef tanks are designed with built-in filtration systems as components of the kit, it is critical for you to mull over what precisely the capabilities of the filter are.

It is highly suggested to purchase the one that comes with a three-phase filtration system as this would execute a more excellent job of keeping tank water clear of any contaminants.

  • The shape and size of a nano reef tank.

This is a valuable factor to toss around since it directly affects things like the number of fish that could dwell inside the tank, heating as well as the space that it would take up.

Generally, a larger tank will call for a larger heater. And, corals thrive best in heated waters at approximately 70 – 85°F. Besides, while it is true that larger aquariums would take up more space, this could hold more coral and fish.

As for the shape, nearly all nano reef tanks are built as cuboids or cubes. Be that as it may, a few are modified and are built with different shapes and full view to significantly enhance the viewer experience. These designs are absolutely preferable as compared to plain cuboid or cube aquariums.

  • Reliable Lighting System

Surely, a good amount of lighting is deemed necessary to promote coral growth. Corals call for actinic blue light which is commonly prevalent in LEDs that come with high color temperatures. This conveys that it is a must to look over for temperatures that exceed 10,000K to ensure more excellent outcomes, particularly in saltwater reef tanks.

Meanwhile, for freshwater reef tanks, a range of 6,500 by up to 7,500K would work more effectively to enable healthy coral growth. In connection with this, lighting plays an essential role in flaunting the dynamic colors of the corals and fish. And, with its additional effects like cloud cover, daytime and nighttime cycles, stunning illumination, your aquarium would have the most captivating views.

Hence, it is substantial to ensure that you invest in a nano reef tank that possesses more than one light channel to enable more awesome lighting displays.

Frequently Asked Questions


What size are nano reef tanks?

Most experts consider the capacity of nano reef tanks to be 30 gallons or smaller. However, there are a few 40-gallon models in this marketplace. So anyone looking for more space should be able to find suitable options easily.

But generally, most nano reef tanks range from 5 to 30 gallons. An excellent example would be Fluval’s SEA EVO XII Aquarium Kit. It offers a 13.5-gallon tank where owners can fit multiple fish while meeting their basic requirements for thriving.

What fishes can you keep in a nano tank?

Nano reef tank owners will want to look at getting the smallest fish possible. If they do, it’ll allow them to keep a substantial variety of fish inside their tank. My favorite choices are pygmy cories, clownfish, and tetras.

In fact, these choices allow me to have multiple of each fish inside my 20-gallon tank. It creates the exact nano reef tank setup I imagined when buying one.

One rule of thumb to keep in mind is every inch of fish requires at least 1 gallon of water. Therefore, whatever fish you choose, ensure you don’t violate this established rule.

How many fish can I put in a 10-gallon nano reef tank?

Fish vary drastically in size, so it’s only possible to answer this question by knowing the species. However, there’s a guideline aquarium owners follow when crafting their setup: one inch of fish per gallon.

So if you have a 10-gallon nano reef tank fish aquarium, it can hold 10 inches of fish. So depending on your chosen fish, it could mean multiple or only one. It’s another reason why it’s essential to consider your fish inhabitants before selecting a tank.

Of course, there are other factors to take into account as well. Putting decorations inside the tank will reduce the water volume and, consequently, the number of fish you can put inside the aquarium.

Plus, you should not overlook the fish’s nature. Territorial species, such as tetra or red tail shark, will fight with other fish if put in an enclosure that is too crowded.

What are the top-tier corals for stocking a nano?

Anyone looking to stock a nano with corals should consider soft, mushroom, or polyp corals. I haven’t encountered a single aquarium owner who doesn’t love these coral types. They all have a reputation for being outstanding additions to nano reef tanks.

Each type’s presence will help craft a unique and appealing environment for your fish. They even come in various colors to match your tank’s aesthetic. You won’t have issues finding mushroom, soft, or polyp corals for sale to fit seamlessly.

What are the most trusted nano reef tank brands?
