Well, I wouldn't attempt to keep anything with a shoal of Piranhas; besides some neon Tetra's. I have however had great success with Blue Gourami's, Oscars & Corys, the Gourami even bullies them on occasion.
In the past I've kept, Gar, Plecs, Silver Aro's & TFB's with RPB's, but not with any more then two RPB's.
