Wont touch the krill, way to small for silversides. hes only about 3 inches in diameter, with a max lenght of about 3/4 inch on the tentacles. Hes still a baby.
My clown also didn't eat much in the first week or two that I had him. Now he will eat flakes right from my hand. He also likes frozen brine shrimp... not nearly as much as the flakes though.
