Sand-like Spots on my yellow tang

[A Wooly]

I’m fairly new to reef tanks so I apologise if this is in the wrong place.

my tang has around 8 spots on its tail. None of my other fish have any. They are only on its tail and look like grains of sand. I have attached a picture but she is a little camera shy. Any help is appreciated. Thanks

Looks like he may have lymphocystis. A viral infection. It's not curable but is manageable. Try to maintain a rich diet and great water quality.

Lymphocystis What You Need To Know: * This is a virus that many fish carry for life. The white nodules (cauliflower-like growths) can grow both externally and internally; so symptoms are not always visible. * There is no known cure for Lympho. However, feeding vitamin-enriched foods and...

Yellow Tangs present Lympho a lot. For helping the fish's immune system to suppress this virus, adding Beta Glucan to the food can help. I mix 7-8 different frozen fish cubes. Let them "slump" in the fridge in a bowl. Strain off the excess liquid as it can cause your nitrates and phosphates to spike. Mix into the food a 1/2 capsule of BG. Can add a scoop of Focus if you want it thicker. The mix will stay good in the fridge for a few days. My fish love the mix.

OP, it’s lympho. Feed it a good healthy Herbivorous diet, keep up with good water quality and it should go away on its own.
