Went through the pictorial guide sticky but really couldn’t walk away with a solid conclusion. Please help ID. Not eating and breathing rapidly. =(

TIA

Can you look at the sticky about hints and tips regarding posting a problem report? That will give you some idea as to the background history that we need to have first.
How long has it been like this, what are the water Chemistries, what other fish are in with it, how long have you had it, how was it quarantined, etc. A short video is also helpful. Have you tried any treatments yet?

I see mucus production likely from an external parasite, but I can’t say which one, in descending order; brooklynella, bacteria from an injury (is its mouth and tail fin damaged?), Amyloodinium or even a advanced case of ich.

100gal mixed reef tank 6 months old
I’ve had the Kole tang for 4 months,
it’s tankmates are lemonpeel Angel, yellow tang, blue hippo tang, pintail fairy wrasse and 2 bimac anthias
All the fish went through a strict QT from marine collectors (I know it includes many treatments and every fish I’ve ever got from there is extremely healthy. I can get you the exact QT details if needed)
First noticed today but thinking back didn’t see the Kole eat yesterday either. So two days possibly
tail fin and mouth do look slightly damaged
Water is Ammonia 0.00, Nitrite 0.0, Nitrate 5ppm, Phosphate .03ppm, PH 7.9
Salinity 1.026
No new fish has been added for 3 months
Recent changes Added copepods from online vendor, and some macro algae
Tank had an algae bloom from auto feeder going crazy while out of town. Still dealing with some reminisce but mostly in the clear
Things to note tangs are aggressive toward each other
Added snails and shrimp about 2 months ago
Thank you Jay.

Thank you Jay.

Based on the history, I think you can rule out the common protozoan diseases. Flukes are also unlikely. Just spit balling here - what if the tangs go into a fracas and this one ran into some rocks and got wedged in/damaged?
