Yellow Tang Problem...

I have had 2 mini reef tanks for several years and recently consolidated them into a 90 gallon. There is approximately 90 lbs of live rock which half I’ve had for 3 years and 60 lbs. of live sand. For filtration there is a protein skimmer and a wet dry. I’ve just ordered a refugium. Water parameters are where they should be: ammonia= 0, nitrites=0, nitrates=0, PH=8.2, Phosphates=0, salinity= 1.024.

I have recently purchased 3 yellow tangs for my tank. The LFS where I buy my fish is a good store as their stock is usually in great shape. The LFS is adding new display tanks in their store and the tank that the tangs where in was not lit with light properly due to their construction. When I got them home I noticed they had the beginning of HLLE. One of the tangs had a weird white spot on his dorsal fin that looked like a wound. It is not ick. In the last week these white spots have appeared on the other 2 tangs and the one with the original spot has a few more. They are in the same location and do not seem to get any better only spreading slowly, meaning they never fall off. The spots are also larger than ick spots and look fleshy. The spots are also raised- similar to ick. I have caught some fresh water fish fishing that had something like this on them. I’m sorry but I can not get a picture of it. The fish are very active and have huge appetites. They are very nervous and spooky. Unfortunately I did not quarantine them and I’m paying for it now. They are the only other fish I’ve added since the consolidation.

For fish I have the 3 juv. 3 1/2” tangs, 2 1” onyx clowns, 1 2.5” yellow wrasse, 1 2” six line wrasse, and 1 yellow clown goby. None of the other fish have this or any other problem.

I feed them prime reef frozen and flake, dried seaweed and algae, formula 2, frozen mysis, and spirulina brine. I’m going out to buy nori and selcon today as well as a cleaner shrimp.

I have been researching goggle for a few days with no results and need some assistance please.

Thanks for your help!
 
lymphocytosis maybe, I had a clown that came down with this. With out a picture its kinda hard to tell.
