Is my toadstool dying? Or just fragging itself?

[Kiiyo]

It's had this white area for a few weeks now and slowly got bigger and now has gone completely to the other side.

Any reason to be concerned?

Following. I have one doing the same thing. It just appeared a week or so ago. I thought something bit it but im not sure. Ive had the same fish for quite a while. My lights are just now ramping up, mine has normal polyp extension later in the day. I have another that divides and drops a baby once in a while but it is always on an edge.

I've had the same thing happen where its on the edge. I just don't want it to nuke my tank. Lol

It came from my tank that's a couple years old, but I recently upgraded to a larger tank. It gets about 200 par and I feed heavy a couple times a day but my skimmer pulls everything out so my nutrients stay pretty low.
