My festae and rainbow cichlid will only eat pellets that sink. Tried all the Hikari brand pellets that float, they won't touch them. They only pellets they tear into are Hikari cichlid complete, they sink. Any other good sinking pellets out there? I heard of kens pellets and looked at the site but I don't know if they are quality pellets. Also they tear up Omega one kelp flakes. This makes me happy that they'll get their veggies!
