Has anyone had this problem before. I think I remember years ago having the same problem, but I don't remember if I found a culprit. Two days ago I noticed a single zoa without pedals (but still alive) today I found another single zoa next to the other one with most of its pedals missing and they are both still alive. There are about 10 polyps in this colony. I imagine another one will be messed up tomorrow. Do you suppose a bristle worm that is starving would eat them? There are no fish in this aquarium so I don't feed the tank anything.

What do you guys think?

I'd look ever so closely at that colony.  Magnifying glass, digital photos, take it out of the tank, etc.  Look for a nudibranch or other unknown critter.

I did think about a nudibranch. I don't know how long their gestation period is but I haven't added anything to this tank for at least 5 monthes now. I'm not ruling it out. I do have some hydroids living somewhat near the colony. Thats all I have. I wish I had some type of aquarium telescope.

Thanks for the advice guys, I'll look more closely.

How are you Adam?!

The zoas look otherwise healthy. They are still opening and don't seem irritated by what is going on. They still are open so that I can see their center. Its just like they the pedals fell off.

Sorry I meant to put a smiley next to the telescope thing. I will be observing tonight, and I will be taking the pictures in a little while after the lights go out.
