I have a small blue tang who has always scratched himself since introducing him about 3 weeks ago. But his scratching has gotten worse and now I don't know if he is scrapping his scales off or if this is marine velvet or what. ? He eats well and is active. I've never been able to spot or watch respirations, etc. so can't really give that data. I do not have a quarantine tank.
