This is a discussion on need help with a tankmate !!! PLEASE within the Catfish forums, part of the Freshwater and Tropical Fish category; -->
I have two 4 inch oscars and a 5 inch red devil and about 40 baby salvini cichlids (don't care if they get eaten).
to keep the amount of fish already in the tank an absolute minal is a 125 gallon. now thats with bio-load and everyone haveing their adequate space. ntm adult red devils will fight anyone and anything in under 100 gallons. either one oscar or 1 red devil is what id keep out of that stock list.
