Yellow tang has black spots. Not much inFO on web

[EnderTurtle]

Hey my yellow tang has black spot disease . Bunch of salt grain size black spots on him. He's swimming and eating fine but there are a couple spots on him.

Does cupramine work for treating black ich?

What is the mos effective method? Also why does it seem like every fish I get has some disease.

Black Ich. It does seem like parasite incidence is higher than in the past. This thread would be useful.
