You grew 1 out from 9? I want to try to grow out at least 5. I'm gonna have to get another tank I guess. At what length can you sex these guys out. And at what length did they start killing each other?
majik, when they hit 3 to 4 inches it will be easy to sex them because that's when the females get their black color, like this...
shrimpsauce, mostly pellets then higher protein food when they got bigger. the hump on the male would swell every now and then depending on his mood, check it out... oh and i never added salt...
MaJiKTeRRoR, IME you can tell sex pretty accuratly at 1-2". all my females showed dark black (rather than grey) on their dorsal fins (similar to red terrors or trimac).
Mari, what temperature did you keep them at?
beautiful fish, even the female is impressive
