Zoas becoming "pointy"?

[lastlight]

I have had this happen and over time the affected polyps have returned to normal. i currently still have a few sunny d's doing this. has only ever happened to my sunny d's and god of wars strangely. and these are both on the same rock/area.

i'm unsure why it happens sorry. mine are much more umbrella shaped than what you show. yours are only slightly curved from what i can see.
