do i have a problem?

[sethfloydjr]

My tank is about 9 months old. Since the very beginning i have had these Zoanthids and they have been fine and have even tripled in number. They came attached to the live rock they are on right now. Over the past week or so i have noticed they are not as lively looking and dont seem to open more than what you see in the picture. I have checked and rechecked my water and everything is normal and fine in it. The temp is fine also. I give my regular dose of supplements and vitamins as I always have. Basically nothing has changed recently that I can nail down as to being the culprit.
Any ideas of what might be going on here?

somtimes zoas just close for a week or two. They should be fine. Just make sure they don't look like they're "melting".

How old are your lights and what type of lights are you using?!?

In my experience, this seems to be pretty common.. just wait it out, maybe check your params
