My ycg eats frozen Hikari mysis, frozen angel formula, nori, MarineGro pellets, bits of frozen shrimp and plankton, brine, cyclopeeze and squid. When I first got him he wouldn't eat at all, it took lots of coaxing and multiple daily feedings of different foods each time to get him to do more than sample. One day he up and decided that he loved pellets, and he's been a piggy ever since.
