Acro browning

[AcroZach]

I have an acropora frag that has started to brown and almost looks like the tissue is pealing off of a certain part, however polyps are all out and color is still good. Does anyone know what this could be? All other corals look good also.

Hmmm that's a good question gonna bump it fer ya , I would hope its not any necrosis.

Doesn't really look bad at all in the blue light. Take a pic with the whites up and no blue and it should show discoloration clearly.
