Betta fish generally are aggressive; this poses a difficult task in choosing their tank mates. However, there exist some species of snails that can perfectly cohabitate peacefully with your betta fish in a tank.  Nerite snails are docile enough making them a perfect match for the betta fish. The most important benefit of keeping nerite snails in your tank is that they feed on algae, biofilm, betta pellets, and fish flakes. This helps in keeping your tank very clean.

Caring for nerite snails and better fish is very easy. This is because they enjoy the same environment in the tank. Nerite snails and betta fish thrive well in the same water temperature and quality. Their day and night cycle is the same. However, the tank size for keeping these two creatures should be a minimum of five gallons. The reason for this is to provide enough space as well as for the ecosystem requirements. Large tank size ensures that there is a substantial amount of bio-load for your nerite snails to feed on. This will ensure that the betta fish and the nerite snails remain very healthy in the tank.

Several factors make nerite snails the best tank mates for the better fish. These factors are:

Food And Diet

Water Parameters

This will make the Nerite snails and betta fish perfectly comfortable in the same tank. With all the similar requirements, betta fish and nerite snails will make a perfect tank mate.


Nerite snails are native to brackish and salty water. For the larvae to grow, the water must be salty. Therefore, the nerite snails will not take over your betta tank.

The change in the environment from the native salty water in the natural habitat to the freshwater in the betta tank will check the population of the snails. Ideally, the nerite snails will not increase in number as the larvae will not be able to grow in freshwater.
