I got this fish from a lfs and they said it was eating fine of course I took there word for it (first mistake) I have tried everything under the sun. Mysis, krill, flakes, pellets, kent's garlic, squid. He just spits it back out. I have had him in a 30 gallon with an atlantic blue tang who eats like a horse for about 2 and a half weeks. Any suggestions? Thanks.
