I need some ideas on what I can feed my bolivian ram, yoyo loach, and black skirt tetra. They all hang out on the bottom together and won't come to top the top for flakes anymore. The tetra used to when he was in my last tank by himself, now apparently hes to cool for flakes. I bought the only sinking cichlid food I could find and its very big, the ram tries to eat it but cant fit an entire pellet in his mouth so it takes like an hour for him to eat one. What are other foods to feed all them?
