So my yellow tang will only take a few bites out of the nori I give him. He swoops up all the mysiss I put in for the other fish, do I need to try to feed him nori first and then feed every one else? I'm worried that he can out wait me and the other fish if I try that. Is caulerpa just as good as nori? he seems to eat none stop, I know they eat more than a lot of fish, but how much should I let him eat?
