He eats anything and everything. Brine shrimp that I feed my other fish, large pieces of silversides that he steals from my anemones, any macro algae in there, and daily dried algae. I looked at the picture again, and it does look that way. I think it's because it was such a crappy picture. I'll try to find a better one. He's a healthy monster, and is growing very fast. Thanks for the advice though, I may try nori anyway. Here's a better picture...
