I have had a male betta for a little over 6 months now. Recently I purchased a female to place in the tank with him. I have read on a few places that they aren't supposed to be placed in the same aquarium together unless you are breeding them and then remove one or the other. Well, before I read all that I put them in the same tank together. I have yet to see them fight each other. They don't seem to have much interest in one another either. The male is somewhat of a weenie. She does go up to him like shes sniffing him (like a dog) but doesn't flare or get agressive. I have seen her rub up against him as well. The only time I have seen him flare up at her is when she scared him by going into the same cave as he did. I honestly don't see why they can't be in the same tank, but I have come to you guys for some advice. If they shouldn't be in the same aquarium I can move one, that's not a problem.
