Funny, just the opposite here. They torment everything in the tank. The Cutteri pair is the only species to hold thier own. It helps that they are fast and in with a ton pots and driftwood. The Cuban male not only has never even mothed her during breeding but gets between me and her during cleaning and picture taking to protect her. They have been totally bonded since they were really small. Now that I said that I'm looking for some wood to knock on. Cichlids always surprise me.
