Convict, I think you may be a male and female......Look at the fins on the big one, are they longer and flowing? If so, that most likely a male, the other doesnt seem to have that trait so I believe thats a girl....at least you know their straight now, just some youngin's wanting to experiment....but if they start breeding, they are going to be pretty protective, you may have to move the other fish Oh and change your name.....Just sayin
