tang keeps scraping the sand bed

[jarrett shark]

just got a new orange shoulder tang and he keeps scraping the sand and rocks. I had a problem with flukes in the past but not sure if it is back? should i dose PRAZIPRO again?
Also my angel has some fuzzy stuff on his tail.What is this??
All eating like pigs and also started garlic to make sure

Yes i should of QT but i did not b/c i thought they looked good and am trying to catch the tang and Angel as we speak to see if i can treat in my QT

Do you see any visible signs of spots, injury, etc? Generally if a fish is scraping along the rocks and sand it's because it's scratching an irritation. My first thought is ich, especially since it's a tang which is highly susceptible to the parasite.

Yep, before they spread too much.

I would suspect ich too, esp. the tang, as they're ich magnets. No matter how good a fish looks in LFS, they should always hit the QT before your DT...Good luck with all your other fish not catching it...

Fuzzy could be marine velvet. A pic or two would help.
