I posted a short while ago about a new burrfish who arrived with ich. It's now 12 days since beginning treatment, and we have been at 2.5ppm copper with Coppersafe, as well as prazipro. The fish has been doing well and eating like normal, though I'm worried he's starting to get a little sluggish (could just be my perception though).

I saw the ich spots disappear a few days after beginning treatment, but now I'm definitely seeing spots again, although they don't look quite the same. While some of them do look a little like the salt grains I'd expect from ich, many of them are more splotchy or patchy then what's visible in the photos. I am also under the impression that, this long after beginning copper treatment, I shouldn't be seeing spots anymore. These have been the same for the last 4 days at least. I'm worried this is bacterial or lympho or something else.

Parameters are mostly unchanged:

Ammonia - 0ppm
Nitrite - 0ppm
Nitrate - 3.0ppm
PH - 7.8
Salinity - 1.024

10 gallon QT, no tank mates.

Thanks for any advice.

That still looks like ich to me. Coppersafe is very mild, but that also means it is slow to work. Another scenario could be that you are seeing a mild secondary bacterial infection from the first bout of ich.
I think you should just watch it for now and keep going with the copper.
