It's only been two days. But, I haven't seen him eat yet. I've tried black worms, enriched mysis, nori, and pellets for herbivors. He will run up to the pieces like he's about to eat it then backs off. I have seem him picking at the brown dusting on the back glass but that's it. Going to my LFS to see what they were feeding. But, any ideas or am I being overly cautious for only two. days.
