 |  green star polyp
I have a green star polyp that has done great for sometime now. It was one of the first corals I bought. However, lately it hasn't been opening up around the bottom of the coral. The coral looks good as a whole, but the bottom isn't coming out anymore. All of my levels are fine and the other corals seem to being doing well. Also, I don't think the problem is the bottom not getting light because I haven't moved it and it has been fine til now. Ideas?

well i was using kent micro-vert. but stopped when my nitrates started to rise. I probably haven't used them 3 weeks. But when I did use I never got the impression that the star polyp was eatting it. My other corals seem to look fine.

They are more a symbiotic coral relying on light rather than plankton. In regards to the polyps not opening up as much, try using a turkey baster or something comparable, and dust the polyps off as they don't like detritus on them and try to increase the water movement around them. It should help! _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.

Can anyone suggest some resources (web or print) to check out on basic polyp biology?

It is also possible that your lights are not as powerful as they once were.
When was the last time you changed the bulbs?

Does the light hit the area where they are not coming out? Chances are something spooked them. GSP's tend to do that and will take their time to come back out again. Give them some time. How long has it been btw?
