Is this ich or something else?

Is this ich on this blue tang? I noticed it showed up about a week ago and seems to be increasing.

I’ll have to try and get a video in the morning.
Temp is 78
Ammonia badge hasn’t changed - see pic

I don’t have a way of testing ph on this tank- the Neptune is hooked up on the DT.

I have 2 wave makers running. One is pointing towards the surface agitating the water and a skimmer running.

All other fish seem fine. I just noticed the tangs not eating.
Breathing is normal and they are swimming around like normal as well.

I also checked the copper when I got home from work and it dropped to 2.20, does that mean the clock restarts when it’s back to 2.25?

Those ammonia badges can be tricky, and they don’t always read correctly. I’d say that one is in the alert range. You might want to have the ammonia checked through a second test, just to make sure.

No - you do NOT need to restart the copper treatment. The range is between 2 and 2.5
Even if it drops below 2 for a time, you may not need a full restart, just add some time, perhaps a week. Now - if it drops really low, for a long time, and ich starts up again, then you need a full restart.
