Selecting Your Betta Fish Tank Size

It is a common belief that betta fish can live in an aquarium as small as a cup.

Now, it may be true that they can “survive” in a tiny cup, but is it the best environment for you betta fish?

Not at all.

How Big Should A Betta Tank Be?

The recommended minimum tank size for Betta Fish should be at least  2.5 gallons or larger. To be honest, a 5 gallon is likely the best size tank for Betta Fish.


The smaller the tank the more difficult it becomes to maintain a clean environment free of ammonia and toxins.

A small tank results in less room for error as toxins can build up much faster than a larger aquarium. A small aquarium also requires more frequent water changes and tank cycling.

The betta fish natural environment is tropical and they do best in aquariums that mimic this environment.

This can be accomplished by having plants (real or fake) and have your aquarium heated and filtered just like any other tropical fish.

Always add Stress Coat when setting up a new aquarium.

Stress Coat removes chlorine, chloramines and heavy metals to make tap water safe for fish.

It Contains Aloe Vera, which promotes healing and regeneration of damaged fish tissue and forms a synthetic slime coat to help prevent electrolyte loss.

Stress Coat is proven to reduce fish stress which can occur from setting up a new aquarium, when performing monthly water changes, poor water quality and handling fish.

High stress levels can cause poor health and a weakened immune system, making your fish more susceptible to disease.

Performing 20% monthly water changes with a gravel vacuum will keep your aquarium looking great and your fish healthy.

It is best not to overcrowd your aquarium by adding too many fish too quickly. Go slowly, start off by adding 2 fish and wait 10 days before you add another two.

It is recommended to go with 2.5 cm of fish per 3.7 liters of water. Remember your fish will grow as they mature. 

Betta’s can also be placed into some community aquariums. Decorate your aquarium as you like and try to include some hiding places for your fish to rest.

When it comes to feeding your betta fish we a really good article on the subject:

Betta Fish Myths

1. Betta’s are not killers and can do well in friendly community aquariums.

2. Though betta fish can survive in shallow puddles in the wild during dry season. It is not their optimal environment. Their natural environment are the large waters of Thailand full of plants and vegetation.

3. True, betta fish can go up for air. However, this is mainly to survive in an oxygen deprived environment. They are fish just like any other and breathe through water. So if you need some extra oxygen get an Air Pump for your fish tank to help agitate the surface water.
