Hi, I have a beautiful Jack Dempsey who is about 6". I love his colors but I'm kind of frustrated by his personality. He comes out sometimes but always runs and hides when I come into the room. He comes out and eats then swims around during feeding time but that's about it. I would like to get one more larger and more personable cichlid with him in the 75 gallon. Preferably one that swims around the tank more and is less shy. Does anyone have any suggestions. He currently has some cons with him and a catfish.
