Bleaching?

Hi Is this Montipora bleaching? Basically all same in tank ... Parameters are fine too.

Does not look like bleaching, looks like tissue loss to me.

Have you made any changes to the system lately?

Are you running any charcoal or other media?

Doing routine water changes?

What type of lighting?
