Funny, the yellow coris is the one out eating everyone else's food, so you are spot on there. The leopard is the only one that is not eating at all, but at least has started coming out of the sand for an hour each day. I may have to move him over to the CP tank, but since I have time and they are not showing any signs of Velvet, I think I will dilute it out a bit and see if he won't start eating. no sand in the other QT. I can try to bring it back up in a few days after he starts eating. Bluestar eats a bit, but not with enthusiasm. thanks for the input.
