Mark on Powder Blue Tang?

[Outatime]

Hi All

Got this Powder Blue Tang a couple of weeks ago and have it in quarantine, it didn't want to eat for a week and looking real thin, finally got it eating and adding garlic and selcon to it's food, feeding thee times a day and today I notice this round mark appearing, anyone know what it could be? Planning on adding copper to the water but wanted to get it feeding fully first, still won t eat nori only mysis.

Thank you

Anything else in the QT tank? Looks puncture like to me, but others are far more knowledgable than I am for these things.

Tough to see through the water spots (grin). That could be an abrasion, but watch so that if the size increases, you can dose with a broad spectrum, gram negative antibiotic.

Don't delay copper with this fish - coppersafe or copper power can be ramped up over a day if you test for it accurately.
