I recently read that the Clown Loach is one of the few non-Chiclids that would work in a tank (55g) with an Oscar (He's about a year old, 6-8 inches, not too agresive). Is this true? Also, what fish, if any, can I put in there with him. I am moving the other Cichlids out to their own tanks because they are starting to get a little touchy about territory and now the tank is looking a little lifeless with just the Oscar and the Plecos. Any suggestions?
