I had a yellow tang that was owned previously and about the size of yours. She had already been trained on Nori/Sally's seaweed so it really wasn't a problem. Things that I have heard that help are cut it into strips.. Not all the way leave some at the top for the clip to hold onto, but the waving action catches their attention. Also I've read adding a clove of garlic to a sump or canister filter and just letting it decay adds the garlic into the water enticing them to eat.
Do you know what the fish was eating at the pet store where you purchased her?
