Last night while I was looking at my tank I noticed that I had not seen my zoas open up for quite a few days. So, I did a google for causes and found quite a few threads on the subject. Many of them pointing to sundial snails, zoa eating nudis and zoa eating crabs. Just my luck, I had all three!! One of my zoa colonies had a sundial on it, another colony had a crab on it and I pulled out 5 nudibranches. The nudis were quite camouflaged as they were the same colours as the polyps they were eating. I'm sure there are more nudis so I have my tweezers by the tank ready to pull out more as I see them. I would do a dip but unfortunately a lot of my zoa frags are epoxied to my rock work. Tweezing them out so far seems to work well. They are easy to spot when they are on polyps that are closed up, which is usually the case.

Anyway, I thought I'd add this to the thread since I ran into the same thing and thought this would be helpful for others searching.
