White spot on my tang..

[125mph]

I've had him for three weeks now.. I think he had flukes due to white stringy poop, so I treated the tank with prazi and looks like the white stringy is gone now.. However, yesterday I noticed the rear bottom purple fin was a little damaged and not sure if it was another fish that caused it or what..You can see it in the picture below.

He's had two white discharge for a few days now, on his body and today it seems to have gotten larger. I cant tell what it is.. its not ich though.. no other fish is affected.

Any ideas? Eating very aggressively.

Could possibly be Lymphocystis which can be caused by poor water quality and stress. For as I know, there is no treatment except making sure parameters are good and you can soak their food in some Selcon.

does it look raised or flat?

Looks flat.. It appears that he got scrapped by the rocks and the residual of the rock is still on his scales... That's what it looks like but I doubt that it was that.

Okay not sure whats going on, but today I come home and the other side of the tang has a large white discharge like thing on his lower front.. See pictures..

any ideas? Still eating aggressively and none of the other fish affected. I have noticed the clown sometimes attacks him when the tang gets close to the nem.

Maybe fungus? Is this contagious?

I did some searches.. sounds like cotton-wool disease / fungus... How do I treat this and is it contagious? Will it heal itself?

Also, maybe it is the Lymphocystis like scooter said? I dosed prazi pro twice over the last 14 days so I've had to leave the skimmer off, and left my N&P off 7 days ago too.. The white spots maybe developed due to poor water quality?

I have my skimmer and N&P back on as of today.
