I have a yellow tang with with a few spots on his pectoral fins. I've tried to catch him but he gets extremely scared when I put a net and trap in. I don't think there is any way to get him out so now I'm giving him as Much food as he wants and I've included garlic soaked mysis shrimp and flake food. I'm going to try and get some macro feast from reef nutrition because my tang won't touch nori sheets. Any tips?
