I had to put my convict chiclid with my Malawis. I knew this was risky. They co-existed pretty well for a month. When the Peacock got as big as the convict, he decided the convict didn't belong. I saved the convict before it was too late and put him in a a spare 2.5 gal aquarium. Once he is better I'm going to see if my local pet store will give him a home.
