My firemouth and texas cichlid keep flaring their gills, lip locking and going in circles together. I had the texas in the tank first and added the firemouth after.(120 gallon) At first the texas was chasing the FM and now it seems like the FM is sticking up for him/herself. I think the FM is male...atleast thats what the guy at the petstore told me and he has a lot of red on his belly. So my question is could a FM and Texas mate? They are both about 3 inches. Or maybe the FM is just really aggressive cuz when I seen him he look so colorful I had to get him...but he was chasing the other larger convicts around in the tank at the petstore. Thanks for any help. Chad
