Nano Reef Tank Buying Guide
Let’s go ahead and check out the most important features that you need to search for in the best nano reef tank:
Since you are interested in building a nano reef tank, then the capacity of the aquarium is the most crucial feature. First, ask yourself how many species do you want to fit inside the fish tank? After coming up with an answer that you are happy about, the next step is to look for a nano reef tank that has the necessary capacity to hold all your species. However, we do need to mention that smaller tanks are not easier to maintain, quite the opposite. This is because smaller tanks get dirty faster.
The Filtration System
We previously mentioned that smaller tanks get dirty faster. This is why having an excellent filtration system is essential. A great filtration system is going to make sure that the water is clean and that your fish are healthy. Not just that, but it will cut down on how much time maintenance work takes. We highly recommend the Fluval Sea Evo Saltwater Fish Tank Aquarium Kit that ships with a 3-stage filtration system.
Glass or Acrylic
Another important question that you need to ask yourself is either to go for glass or acrylic? Both materials have their pros and cons, and we are going to present them below so that you find it easier to make the right choice.
If you do some research on aquariums, you will quickly notice that glass is the most popular option. The reason behind this is that glass is cheap, and it makes it possible for the manufacturers to lower the price. However, there is a big downside that you need to take into consideration. Glass shatters easily, and aquariums that use it are available only in square or rectangular shapes.
On the other hand, we have acrylic that stands out with its versatility. Nano reef tanks that use acrylic are available in all types of unique shapes that enable dynamic panoramic viewing. The JBJ Nano Cube LED Aquarium is a great example here. To make things even more impressive, acrylic is 17 stronger than regular glass and very clear. The con is that while acrylic might be more durable, it gets scratches really fast.
Frequently Asked Questions
Are nano reef tanks hard to keep?
No, nano reef tanks are not hard to keep. The only difference, when compared to regular aquariums, is that you need to pay more attention to maintenance so that things don’t get out of hand. Otherwise, you will need to take out the water to do a proper cleaning. A high-performance filtration system is your best friend.
What is a nano reef tank?
If you are new to aquariums and you are still wondering what classifies as a “nano reef tank,” then you should know that it is their capacity. This type of aquarium holds miniature reefs and is usually under 30-gallons. Furthermore, nano reef tanks are ideal for housing corals, invertebrates, and small fish.
Does a nano tank need a protein skimmer?
Considering that nano reef aquariums are small and have a low volume of water, you will need to use a powerful skimmer in order to make sure that your inhabitants are healthy. A good alternative here is a filtration system that guarantees the water is always in pristine quality.
What fish are good for nano tanks?
Here are the top 10 best freshwater fish for nano tanks: betta fish, dwarf puffer, celestial pearl danios, bumblebee goby, sparkling gourami, Endler’s livebearers, least killifish, Norman’s lamp eye killifish, crystal red shrimp, red cherry shrimp. The rule of thumb that you need to follow when selecting fish for your nano reef tank is to look for small ones that are not very active because they will not have lots of room to swim.
How many fish can there be in a nano tank?
First off, we want to highlight that the answer to this question depends on what type of fish you are planning to place in your nano tank. Generally, you want to have only 4-6 fish in a nano tank. If you are going for something bigger that has a capacity of 20-30 gallons, then you could place some more species.
