I've never really got into pirhanna i used to keep a group of RBPs but thats about it. i keep A big shoal of metynnis and myleus instead. What size can it reach?
i loove manuellis, not only are they the biggest but they are one of the most aggressive if not the most..be careful when working in the tank because they have the ability to take a nice chunk out of you once he starts to put on some size...good luck and congrats
