zoanthid and button polyp help

[tony7855]

I have had green button polyps and red zoa's for a few years now. the other day i noticed all of them were more closed up and do not open all the way any more. I have not done anything different to my lighting, water, or filtration. Anyone have any ideas what it could be?
