I've noticed alot of posts about anal prolapse and bloating. This is normally due to constipation in the fish. Proteins bind their system. You can help your fishes digestive system by offering them washed fresh rommaine lettuce. They love it and the grazing is part of their natural habit if they were in the wild. Fish naturally browse on vegetation. So throw a big leaf of rommaine in with your cichlids every now and then to help clean out their system. They may freak out at first but they will soon investigate and nip at it to see if it is edible, as soon as they figure that out, you'll have some interesting entertainment for a few hours. Enjoy.
