Purple Tang not purple

[fugetaboutit05]

Brought in new Purple tang to a 55g. Initial days no worries. Right now, covered in white splotches. initially, white dots. thougbt "ICH", but not so sure that is the case at this point. less then 2 weeks in the the display and this happens. QT for a approx 6 days with no signs of distress, or disease prior to adding to main display.

ALL OTHER INHBITANTS CLEAR OF DISTRESS OR PARASITIC INFECTION.**

DP TANK SPECS :

55G, REEF SALT, PROTIEN SKIMMER, UV FILTER, (2) PH, EHEIM 600 CLASSIC FILTRATION WITH ADDED CARBON, 5 OTHER TANK MATES APPROX SAME SIZE ( 2.5" - 4.5" ALL JUVINILES)

Any advice is greatly appreciated. This guy was pretty expensive, but aside from price point, i dont want to lose the fish.

Currently using the HERBTANA parasite expellant, nothing withn copper due to the INVERTS inhabiting the tank.

Pics of the fish will help the experts. From the sounds you may want to get a hospital tank set up just incase.

Edit: white light pics. Blue won't do a lot of good.
