make sure you have large enough tank for him b/c they are messy eaters adn need adequate space and filtration both(whichever species you choose), always check your tank mates for compatibilty, they will eat anyting they can fit into their mouth(literally anything)
and NEVER EVER fed them feeders, ween them immediately to fish food adn keep them there, do not feed them freshwater feeders, although cool to watch fw fish is very bad for them and DOES normally cause health problems
