I have two three spotted gourami's in a 30 gallon tank. My male picks on the female a lot and I wanted to add a few others in there to maybe see if that helps with his aggression and also to make the tank less boring looking. The tank is huge and I don't see why my male is so territorial, he chases the female all over the place. I have a lot of plants towards the back of the tank as well as sea shells and rocks for my female to hide but doesn't seem to really work, the male just goes in after her.
