Whats wrong with my tang?

[mnestroy]

My Powder Brown Tang has had discolored patches in his skin for a year now, they come and go. But this one I saw yesterday was the largest I've seen in a while.

Additionally his fins look horrible.... He very active and eats a lot.

What is strange is I dosed some garlic yesterday and his dot is have the size and almost gone... I think its highly unlikely the garlic could work that fast (if at all) but I figured I'd mention it.

The 2nd Pic is prob the best, but its hard to tell in all 3 how bad his fins are...

I have been feeding him strictly Rods food, should I also give him something else to help his diet?

Thanks

They could be possible stings from corals.

What type of coral?

Would a LTA do it? he often hangs out near it ... trying to be one of the clowns.

Kinda looks to me like it has HLLE. I would start giving it more greens in it's diet. Rod's food is mostly meat based. Acanthurus tangs need lots of greens in their diet.

Thanks I'll give it more greens and see what happens.

chop some fresh garlic and mix with the food, it may help.
