Blue bumps on blue Tang

[Keywest99]

I received a 2 inch blue tang a week ago from Reefbeauties. They hold their fish in hypo salinity for 5 days with copper treatment before shipping. It arrived at 1.017 SG which is what I had my QT set at. I kept him in Hypo for 7 days, then slowly raised it over a two day period two 1.024 before placing him in DT. He looked fine and was swimming good, but after two days it appeared to have blue bumps the same color as his body about 1 -2 mil in diameter and he is hiding in a corner. I have not been able to get a good pic yet but will continue trying. Any thoughts would be appreciated. Thanks!

1.017 is not true hypo which is 1.009 and the quick copper at 5 days very ineffective as it takes 2 days for copper to start working.
Please post pic(s) of fish under white light intensity for best assessment
