Mark on Powder Blue

[ReefKeeperElite]

First time with powder blues, not sure if this is a scrape or the start of a disease.

Transferred to DT from QT 2 months ago. Was treated with copper power for a month, 2 doses of prazi, and observed for a couple weeks.

Also in this QT batch were a yellow tang and hippo tang. Already in DT are juvenile emperor, 6 banded angel, and 2 oscellaris clowns.

No other marks on the powder. No other signs of disease like twitching or breathing heavy. Eats very well too.

Should I be concerned?

The photo isn't super clear, but it just looks like a scrape to me. Really serious communicable diseases won't have a diffuse spot like that with no other symptoms. It bears watching of course, but I don't see any treatment needed at the moment.

Thanks Jay! Yes, I’ll keep an eye on it. It looks like a scrape mark, but I wanted to be certain as I’ve heard many horror stories with powders. He darts across the tank and through the rock work super fast, so it seems likely a brush against something could easily happen.
