TLDR: Anybody know what's causing this or what else I can do?
This monti has been growing successfully for years. Now suddenly there is a giant white patch in the middle. It's growing. I've been watching it for pests, and I can't spot any. I can't remove the rock it's attached to without taking down the whole tank. I've already gotten a healthy frag and put it in another tank. (Unfortunately, they both have the same sump--I don't have separate water systems running--but at least they are separated.) The rest of the system looks healthy.
One thing I think is interesting is that the point of origin of the bleaching seems to be where the monti has been fighting with a zoa colony. Are there monti pests that hide in zoas? Or can the zoas damage/weaken the monti enough to encourage an infection? In the latter case, I would have expected this to be even along the boundary, and it isn't.
Any advice welcome!
