Yeah I noticed it early enough. I've had similar problems with Platys & Bolivian Ram Cichlids. That's why my son's 20 gallon has the 2 Platy males that get along and the wimpy Honey & Bolivian Ram males. My 20 gallon has the mean Honey G, the mean Bolivian & the mean Platy.............go figure. They're all getting along well in each tank so far.
