Yellow Tang with Black Spot disease

[smokinreefer]

FWIW i have had experience with black spot on my yellow tang.

he was the first tang in my tank. i noticed the black dots appear on my tang, because he had started the occassional scratching. i introduced a pair of cleaners. if i remember correctly, it was probably gone in a week. and has never come back.

now i cant say it was strictly due to the shrimp, but i notice the shrimps usually are aggressive, active cleaners of newly introduced (fair sized) fish. but my fish arent actively cleaned by the shrimps anymore...but then again my fish are not sick now either.

i believe, and in my experience, if you have a healthy environment, good water quality, a good diet of foods, lots of greens...and cleaners of some sort,...i am sure your tang can overcome this (and ick).

tear down the tank and sterilize???...that sounds pretty drastic to me.
