Hey guys just got my first tang and he went through TTM wonderfully. Been in my DT two weeks, now he has developed these white markings. He eats and acts perfectly fine. All other fish are fine as well. So no idea, please help. Thanks!

Also worth asking, could it be burns from euphyllia or anemones?

Did you QT him? Have you done a 5 min FW dip?

Marks like that in a straight-ish line usually are from tangs wedging themselves into the rocks or up against a coral at night. Beautiful fish BTW.

Thanks for the info, and yes I did qt. 2 weeks TTM then two more for observation. Didn’t see a need for fw dip as I did two doses of Prazi during qt.
