Hi all, so I have a powder blue tang, he used to eat very well before catching a bacterial infection/fin rot off a new angel I got, got him to a quarantine tank and the fin healed well. However now that he's back in the main I see he's quite thin. He still eats pellets but he does so in a slow manner compared to his lightning fast movement before this infection, he'll let pellets drift by before attempting to go after one, additionally he used to love nori and munch on pieces galore, now when I clip it to the side he swims over to it and seems to struggle staying near it but either doesn't take a bite or nibbles on the edge for a second before stopping. Are there any foods (maybe garlic?) that would encourage him to eat more? Any solutions to getting his weight back up?
