flashing yellow tang in QT

[Burrito]

i have been following hotrocks QT procedure for the last 15 days with my yellow tang, kole tang and bluethroat trigger. they have been AWESOME since day one, eating all the medicated food and swimming around happily.

i noticed for the first time my yellow tang was flashing around a bit, not a lot but randomly 2-3 instances at a time. only distriburbance yesterday was a 25% WC with copper levels matched. i've never had tangs before, is there something i should look for or do? i was planning on switching them to non copper water on friday and start prazi.

Flashing could be due to irritation from copper. Are there any spots or wounds on the tang?

This^^^^ Or an itch like skin irritation not ich. Or if flukes are present flashing is very common. Id finish copper and then move to prazi as planned.

I usually only feed food soaked ABX for 14 days, unless I am seeing white stringy poop.
