What is wrong with this zoanthoid?

[Jyetman]

Can someone tell me why that one paly is doing that? I've had this colony for three years and never seen one do this before like it inverted or something? Two months later another one did the same thing the others look fine though.

No but replaced my 192 Watt Power compacts a year ago with 160 Watt Razor LED system and that's when things changed. Not sure if its missing something like more or less intensity very frustrating.
