Sorry, Wasn't sure where to put this post as they are not realy catfish? In my African tank I keep a few Peixe - Algae Eater Albino (Gyrubicheilus Aymonieri). Many people complain about them and do not like them but they do a fantastic job in the tank and are not nearly as messy as a pleco. They can get rather large do you think if I put a few in with young oscars they would make it? I'm starting to get allot od algae patches in my oscar tank?
