not to many people have been talking of these fish,so I dont know if mine is behaving normal.The rate of growth,appetite,bahavior???Im the only person I know that has one,if one of you guys has one,tell me about it.Would be neat to compare fish,you know.Hope IM not the only one that lives with an aquatic antichrist,anything and everything I put with him he kills.His blue fins light rite up,copper in the gill plate,teeth!!!!!He is ..the devils reject.Sleeps during the day,really active at night,digging ,aswell as tree removal.Very smart fish,I think he knows whats going on ...............hes looking at me.......
