Kevin, the Convict is actually THRIVING...
It sticks up to both Midas now. Mostly it tries to stay out of their way, but it's not afraid to get into a confrontation. Knock on wood, none of the fish inflict physical damage on each other, they just chase each other around a bit. The male Midas is twice it's size. The Convict is a chunky one though. One tough customer.
Say, does anyone know how to visually tell the difference between a male and female Convict? Just curious...
