the convict was a female and the firemouth was a male... it didn't matter what my water conditions were in my tank these two fish breed all the time... in the summer my water temp would be 80 deg. and in the winter time temp. would be between 76 --> 78 degs.... to keep them from breeding i had to separate them... when the babies got between 6 to 9 months old they had the body of the firemouth and the markings of the convict...
