Yellow and Purple tang not eating after copper

[reef aquatics 101]

I just dosed some copper for my qt on Tuesday and now my yellow and purple tang won't eat. they used to eat fine before and wont eat now. I did a good water change and added some media to my filter. Any idea what happened. They are also really small about 2 inches each

What copper brand did you use? How much did you administer, how quickly, and what are you using to test?

Also copper is an appetite suppressant, how long have they stopped eating for?

In addition to knowing more about the copper and the dose you used, what is the current water quality testing out as?

A short video is often really helpful for us in getting an overall view of the tank.
