What's wrong with my Chevron Tang

[PatriotsFishin]

Any idea what disease my sick tang might have? It is one of 5 tangs in a 125 gallon tank. Here are a couple of pictures:

Also any idea what how I can treat it in a reef tank?

I have had him for over 3 months. He has been this way for about 7 plus days and the condition doesn't appear to be getting any better or worse. He is eating well. I feed nori, pellets and frozen brine shrimp. The PH is 8.3, salinity 1.025 other elements within normal range.

Any ideas are appreciated!

Thanks!

Looks like the beginning of HLLE.

agreed except that its a little past the beginnig stage are you sure this is recent because it looks prety bad and it usually dosnot develop over a 5 day period

The damage hasn't been there that long. I formed in less then a week. With the other fish and corals doing so well, this has me in a panic.

How do fish get HLLE?

Good luck and hope he gets better, Chevron's are beautiful fish

What other tangs do you have?

Unfortunately, the tank gets very little direct sunlight! I am going to change the diet and see if that helps. Thanks for all of the suggestions!

Just curious to see if the diet helped, hope so
