ok, well in that case, do i need a bigger tank so i can get a betta for my community? i currently have 4 dalmation mollies, 4 cory's, 3 lyretail guppies, 2 red honey gourami, and 5 baby cherry barbs. it is a 96 litre tank
As long as you keep up on tank maintenance it should be fine. The betta will be more than happy in a 96 litre tank. Just make sure your ammonia and nitrite levels stay at 0. Regular water partial water changes, etc.
