Does this look like ich?

Thanks! Out of curiosity, would using hyposalinity in conjunction with copper shorten the quarantine period for the foxface? A 29gal tank is pretty cramped for a 7" fish.

No - both treatment methods take 30 days to reduce/eliminate the resting tomont stage. Running both together really won’t enhance that, but can be more stressful to the fish.
