black belts

[god61021]

i have a 1.5-2 inch blackbelt ,the book i read told me they were peaceful that does not appear to be the case.i am wondering if anyone can tell me about possible tank mates for him/her? right now he /she is in with 2 chocolate cichlids(temporalis),an albino oscar,a firemouth,and a marble goby,all of comparable size so there is no aggression yet.the firemouth is coming out cuz hes a prick.im wondering could a blackbelt live with these species?they are in a 55 gallon now but will be in 125 in a few months.i also have an extremely aggressive reg.pleco in there. i thought if needed i can put the blackbelt and the pleco together?well any thoughts would be appreciated.
thanx dave

My experience with Blackbelts is that they are hardy and can put up with quite a lot when they are the underdogs, but before they become the largest fish, they become dominant and are relentless in ruling their territory and driving others away. Only the armor on the Pleco, and the hiding spots he has has kept him alive in this tank. Even a Jack Depsey (very territorial) that was 1.5x his size was no match for him when he was just a juvenile. I wish I could upload some videos of him when the lights in the room are out and he can see his reflection in the glass! WOW!

Think about it.
