Ich or Velvet around 2

[chasingcorals17]

Recently had a velvet outbreak and got whatever remaining fish into QT. Going on day 9 of copper treatment. My hippo tang had a vicious velvet coating while in the DT before the QT process and miraculously survived. However she’s now sporting white spots. Could it be velvet again or ich?

Copper has been at 2.5ppm using coppersafe. I know it says to do 2.0 but have seen a lot of people go to 2.5 and have very good results without harming fish

The odd thing about Coppersafe is that the bottle says 2 ppm, but if you dose it according to label instructions it tests out at 2.5 ppm

Since the fish is in full copper, my suspicion is that these spots are a reaction to the previous trophonts - either a secondary infection, or natural scarring reaction.

If the tang is eating well, I’d just keep an eye on it.
