Cures For HLLE In Angel?

[rastaangel]

At the moment I have a small juv emperor in QT. Since I picked him up he has started to develop small pinkish colored dots around his eyes and over the top of his head. He eats like a pig, is fed a mix of brine, mysis and bloodworms. Also devours nori with a passion, actually out competes the achilles tang in with him. All foods are soaked in garlic and selcon alternating days. I checked for stray voltage and got none, and theres no carbon being used as I am treating with copper for the next 10 or so days.
Any one got any ideas on a cure/prevention?
