I don't have a big tank anymore, so this is just for curiosity sake. Anyone have experience in having more than one male in a really big tank like 125g+ ? Traditionally Bettas are kept in small tanks, I have one male in a 20g community tank with 2 SAE, 4 Cory, 3 Otto, a few platies. The male tries couple of times a week to pick on some platy but never got into any fights, more like platy just turn and bye. I won't put another betta, male or female, in my 20g. But am curious if it could be done in a densely planted big tank?
