White On Kole Tang Gill Plate

[Townsaquaria]

Hello,

What is this on our kole tangs gill plate? Behavior is normal. Eating, active, but we got as a re-home last week. Thought could be an abrasion or a bacterial or fungal infection. What do you think?

Did this show up suddenly, or did it grow larger over time?

It showed up suddenly. My wife sits next to the tank for work and was watching all day. It seemed to appear between 5-7 pm.

We also wondered if the BT anemone stung it. Not sure if that's a thing.

This was yesterday, same time of day.

That is so strange. The bta might have done it, but the pattern in the lesion is throwing me off. Still, if it showed up abruptly, then doesn’t get any worse, you can rule out an infection.
