FAQ:

Q: How many bettas can I keep in a five gallon tank?

A: You should only keep one betta in a 5-gallon aquarium, as they will fight others of their species to the death if kept confined.

Shrimp are one of the top fish people like to keep in these smaller aquariums, due to how small they are themselves.

Q: How often should I clean a 5 gallon Betta tank?

A: You may clean the filter once a month for a 5-gallon tank with one Betta fish. It is not advisable to clean a filter weekly because the filter houses most of the beneficial bacteria you need in your fish tank.
