Blonde Naso Tang Stopped Eating

[benscorals]

My blond naso has been in QT for 4 weeks now. The first week he went through 2 weeks of Chloroquine and was eating ravenously. Then I did a tank transfer and moved him and all the other fish into another QT system and waited 5 days and he was still eating fine and then started Prazi. Immediately stopped eating however all the other fish continued eating just a little less than they had before when they were in the chloroquine. I waited 5 days then did a 25% water change on the system and then dosed again. Then I waited 3 days and did 2 25% water changes in 2 days. All the other fish are pretty much back to normal but he will still not touch nori. He is a full-grown adult with streamers so he has never eaten anything but the nori but now is not eating anything at all. Any tips or tricks to getting him eating again?

He is still pretty fat for not eating for 10 days but I want to get him healthy as soon as possible.
