I have a 25 gallon tank with a few small young cichlids in it, I think 3 of em are some type of melanchromis. I also recently added 2 new cichlids, called red something, though they are orange in color. My girlfriend brought home an angelfish, he is about 2 inches in body, about 4 and a half with fins in height. Can I put him in the tank with these other fish?
