Dussumieri Tang with a spot

[Nlara]

I got this tang on Friday. Looked healthy. It’s in a large 120 with other fish I picked up. Technically it’s a qt tank since nothing was in it. (Fully cycled I just moved everything a week prior into my 500). I treated with prazi a couple days ago because my gem looks like it has flukes (on the eye).
This does not look like ich or velvet.
many ideas and how to treat?

Fish is distant in pic which is also fuzzy but preliminarily, Looks like an injury from a nick or similar. Please provide closer and clearer pic under white lighting and keep an eye on area for progression of infection.

Agreed. Not ich or velvet. It likely swam too close to a rock or something. Still getting use to his surroundings. I have an almost adult Dussumieri Tang and he or she will sometimes dart into the rockwork or into an acro and cause injury. Just keep an eye on it and make sure its healing.

+1 on it being a nick or cut. Just watch that it doesn't grow larger, or spread to new areas (signs of infection).

What fish did you acquire at the same time? I see the tang, an idol and a wrasse. Are there others? With any large group of new fish, there is a risk of protozoan infections. Have you thought about running hyposalinity? That would at least control ich and flukes, but it won't help with velvet like copper would (you can't run copper because of all the carbonate rock in there).

The spot just went it away when I came back from work yesterday.
I don’t have a wrasse in there. I got the fish at the same time (dussumeiri tang, juvenile chocolate tang, moorish idol, gem tang, purple tang) all introduced at same time.
I completely forgot about running hyposalinity.
I could run copper just never did in the past 7 years. Just never did.

Thanks! Literally over a day that spot just went away. Not sure why but the spot is gone.

Thank you. The spot just went away when I came back from work the next day. Didn’t think it would clear that quick. Not sure what it was.
