Hey all. Looking for some advise from some more experienced tang keepers. I recently purchased a juvenile clown tang probably 2.5”-3” long. I believe he is a wild caught specimen. He will not eat prepared foods. Frozen or pellet. He does continuously pick at the rocks for algae. He will not even go for the Nori on a clip. He is starting to look a little thin. And ideas on how I can convince him to go after the other foods provided him. He pretty much has the rocks picked clean and I hate for him to starve himself.
