hahahahahahha
yeah man I was gonna say it but someone beat me to it. HRP are a totally different species. They look similar, but they have that name to differentiate them between the convict. They are something you could keep with like dwarf cichlids in a 30, but not a convict.
My con owned all my fish in my 75. He would bite their side and he was just relentless. Out of all the fish I housed with him in his lifetime (jack dempsey, severums, oscar, green terror, texas, nicaraguense) the only one that ever faught back was the nicaraguense. This resulted in one side of the tank with 4 fish with the nicaraguense, and the other half of the tank all to the convict.
He is in a 29 now in prison after he bit some scales off my gold oscar.
Basically cons are mean and don't put stuff with them unless they are fast and fend for themselves too.
