White spots/cotton candy on my Yellow tang

[BlackPanther]

Hello Everyone,

I wish you're all doing well. Actually this is my first post here and I need your help.
I have set up my aquarium 3 months ago and it's running well as I can observe as a beginner. A couple of days ago I've lost 4 clownfishes IN ONE NIGHT. First, when I checked the clownfishes they had white spots/cotton candy on their fins and body, the next day they were gone.

Now my yellow tang having the same issue (which I couldn't identify it's reason) and I can see her spending more time in front of the flow motors/pumps.
I have a purple tang, clown tang and Kole tang in the same aquarium. I've checked the parameters(That I can check) yesterday and it was like that :

Alkalinity	Calcium	Phosphate	Magnesium
8,6	460	0,24	1440

Salinity	Temperature
1024	25

Can anybody help me telling me what should I do in such a situation? I don't want to lose more fishes
Thanks in advance!

Sounds like your clownfish had Brooklynella (aka Clownfish disease). It can kill quickly and can infect fish other than clowns. Here's a link with lots of good info. Sorry for your losses.

Could be Ich on the Yellow Tang. Sounds like you added quite a few fish in a short time period which would add stress to the equation. Hopefully the rest will make it.
