no, they are to small. get a 5 gallon with 4 bettas ... FEMALE not male because they attack every other fish .. you could have 3 guppies with them as well ...
hope it helps:)
One Betta needs 5 gallons each. 4-6 females need a 10 gallon or they will tear each other apart from lack of territory space ....
Betta condos are horrible: they are too small! All bettas should have at least 5 gallons with a heater and filter.
Please don't use condos, they are terrible!
U betta not lololol
