First it was black ich...we treated then this showed up killing one yellow tang and maybe another.Our naso tang died after the black ich treatment made him seem sicker,then he died.Now one more yellow tang has it. We've looked in our books but can not find anything like it.

Wow, that is the most disgusting thing I have ever seen. Clearly you need to qt the fish you are buying before putting them in the main tank.
Something is flawed in your system, you should do a total re-evaluation of the system and figure out what is wrong. Also consider purchasing a UV sterilizer. I would definitely not buy any more fish until you figure out what is wrong.

Buy a good quality test kit and list every single paramater on here after performing three tests of each and averaging the results.
DEFINITELY test for ammonia,nitrite,nitrate,salinity,temp,phos,alk,pH,
What all have you put in that tank. Consider using a few poly-filter pads to draw out impurities like copper from your water.

I don't know what your others had, but it does SOUND like it still may be black ich. Could the hole on it's side be from this flatworm attaching itself?
What is Black Spot Disease?
Also referred to as Black Ich, this saltwater fish disease is caused by a small parasitic turbellarian flatworm in the genus Paravortex that takes up residence in the aquarium substrate. The adult worm attaches to a host for about six days, falls off into the substrate, then in about five days the adult body ruptures releasing a new population of young worms and the cycle begins again. It normally does not show up in the larger numbers as with other forms of Ich (Whitespot Disease and Coral Fish Disease) and is not nearly as dangerous. It is a disease that is fairly common with Yellow Tangs and Angelfishes, but can effect other fish species as well.
Symptoms
Black Spot Disease appears on the fins and body of fish as tiny black dots, less than the size of a pinhead. The fish will scratch up against objects in the aquarium and the disease may be associated with reddened skin, lethargy, color loss and rapid breathing. It is easily seen on light colored fish, but is less obvious and sometimes overlooked on dark colored fish.

Maybe Vibrio?
Another difficult disease to treat.
SYMPTOMS:
Ulcerations on body of fish.
Red abscesses and/or red fin edges and rot.
Bulging eyes.
Lack of interest in food.
Fish is not swimming.
CURES:
Very difficult to cure. You can try a solution like that for ICK but chances of saving your fish are slim.

Thanks everyone...I was told to try rubbing him down w/ mercurachrome. Anyone w/ experience on doing that ?Our water tests are fine according to the petstore that tests our water (Coral Sea in West Palm Beach).We use poly...filters in our sump.And we have about ten things we treat our water w/ that the s/w specialist recommended.I'll put a list together later today.
