Palythoa sticking up and out

[mustseefish]

My Sea urchin is walking over my Palythoa and now the paly is sticking up and out like a domed shape can anyone tell me what this is doing?

They will do this when starving for light and even food known as stretching

Fyi, that's a Zoanthus gigantus, not Palythoa.

They will close up like that when things crawl on them, such as urchins and hermit crabs. It will open up later on.

l agree with both previous comments it could be due to lighting and the closed one is probably it was touched by a critter in the tank and didn’t like it to much. Hopefully if moved to a better lighting par that it likes it should fix this problem.
