Blue tang with brown patch??

[reefers4life]

Hi everyone, I got this blue tang not so long ago from my LFS and i asked the same question whether the brown patch on the front of the blue tangs face meant anything. They said it was nothing and i believed them, but I saw that this was not really going away so I would like to ask what is actually is and how do i treat it? Thanks (the brown spot is on the front area of the blue tang below his eye)

Kind of hard to see, but could be HLLE.

Get the fish on a diet with lots of seaweed and vitamin enriched seaweed is even better. Could also try soaking food in Selcon.
