Pink polyps

[nyfan78]

Hey everyone I have a small colony of pink polyps say about 10-15 on a rock. They all used to always open and seems to be healthy and all. Now they all dont seem to want to open. any reason why? My water parameters are on par. So i am not sure.

I have had this issue with zoas before. For no good reason my bambams were doing this. I gave them an iodine dip and they looked great by the end of the week.

Thanks. what causes this?

Really not sure. It baffles me.

I heard the same thing from other members here. I'm sure they will chime in soon. This is a large forum so it is hard to stay on top of all the threads.

Anyone else?

How long have you had the polyps? Has there been any changes in flow or have you added anything to the tank recently? I found out that my zoas were doing poorly due two fish that I had in my tank. I found new homes for the fish and all my corals look awesome.
