Ditto with the bloodworms. Funny to watch my pandas suck up a bloodworm just to have it blown out a gill, then go find it again. I always add a teaspoon or so of wardley tropical flakes to my snail jello, and this time I put in a half teaspoon or so of frozen (thawed) bloodworms and brineshrimp. The corries graze on it when the snails arn't covering it. My brand new kuhlis (just got them yesterday) even came out in the bright of day when I tossed them in. Wardley shrimp pellets and whatever else makes it to the bottom rounds out the diet of my bottom feeders. All seem happy.
