All of my parrots can scarf it down with the best of them. But without a doubt the champion is my baby O Brick. I'd done my research with cichlids and Oscars and heard about their greed...it is absolutely true, I am a believer! Brick is a complete and utter PIG. I portion out a number of medium sized pellets for everyone, usually between 6 and 10 per fish. If I'm not careful Brick will literally grab nearly every pellet. There's this 'spinner' move he does to catch everything at once. He bangs into my big parrot Kong and knocks him away, or snatches the pellets as Kong is lunging for them. He gulped down 12 medium pellets one time last week before I could shoo him away. And don't ask me where he puts it...he burns it off swimming the tank and then two days later I'll see new growth edges on his fins. (He has some now). Kong gets pissed and chases him a bit for stealing pellets.
