Mine didnt eat for exactly 3 days, forumla 2 flakes was the first thing he ate, and what he eats most readily still. I dont think pellets will be taken as easily as they are larger. Id use flakes, crunched into small peices and released under the water so they are not at the surface. Frozen brine and mysis is also taken well. It will not go to the surface to feed like the clowns will.
