stiga Posted April 16, 2007 Share Posted April 16, 2007 I have a colony of brown polyps that have recently (in the past week) started to not fully open. I do have a cleaner shrimp that likes to hang out on top of them but not 24/7. I also have a small pygmy angel but I've never noticed any picking. I've never experienced sick polyps before so I'm not quite sure what I'm looking for. I've attached a pic for viewing. 30 gal. biocube Other corals in tank: small zenia frag small colt frag small green polyp Fish: Med. Maroon clown small firefish yellow goby pygmy angel Other: Emerald crab cleaner shrimp coral banded shrimp Forgot to mention...water quality is good. tested myself and also at a lfs and all is good.

Seanfg89 Posted April 16, 2007 Share Posted April 16, 2007 I have a small colony of Moon Polyps, Cinnamon Polyps, whatever you want to call them. My point is that they are palythoas and they did what you are describing about a week ago. They always opened up nice and big but one week they started not to open or open very little. Then once day they were back open again but had a translucent film on them and after a couple of days they were completely back to normal. As it turns out, some polyp colonies will close up and create a waxy film over the polyp surface and then shed it as a way to prevent microalgae from growing on them. Give it time and see what happens, sometimes my polyps will close up for days at a time for no specific reason. Link to comment
