How Many Bettas In A 20 Gallon Tank?

The answer to how many bettas should be kept in a 20-gallon tank is actually quite complicated.

Generally, it is best to have just one betta per tank, as they are known to be quite territorial and can become aggressive towards other bettas if they are in the same space.

However, if you are looking to house more than one betta, there are certain conditions that must be met.

Firstly, it is important to note that a 20-gallon tank is quite small in terms of space, so it is not suitable for multiple bettas unless it is heavily planted and offers many hiding places.

If the tank is not properly decorated, it is not recommended to house more than one betta in it.

Secondly, the size of the bettas must be taken into consideration.

If you have a 20-gallon tank and you are housing multiple bettas, it is important to ensure that they are all the same size.

This is because a larger betta is more likely to be aggressive towards smaller bettas, so if the bettas are all the same size, aggression is less likely to occur.

In conclusion, the answer to how many bettas should be kept in a 20-gallon tank depends on the setup of the tank, the size of the bettas, and their personalities.

Generally speaking, it is not recommended to house more than one betta in a 20-gallon tank, but if the conditions are right, it is possible to do so.
