I have a cute purple/blue/red fantail male betta. when I put in a blue female betta, he started flaring at her and trying to chase her away! I thouhgt females could be mixed in with males. I was afraid he's hurt her (she's half his size), so I seperated her into another tank (40 gallon) full of semi-aggressive tropical fish and community fish. Think I can add her in when she's a little more larger? i also have another (2nd) female betta that I didn't attepmt to mix in, I put her in with an opline gourami and a neon (10 gal).
Another thing, the opline gourami, I had to remove her becasue she kept on chasing around a gold gourami I have in the 40 gallon. I'm pretty sure the gold gourami (2 inches) is a male, and he is much samller than the olpine (4 1/2 inches). Is this normal behavior? The opline gourami has never harrased any other fish in the tank, and she ignores the ,1 inch neon and female betta.
