![]() FWIW,
I have a colony of "mean greens" that shrivel up to almost pin head polyps, and they always do this.. and always return back to the same plump polyps. I THINK they do this when new polyps are forming/growing. This has been my observation anyhow. Scott

![]() Sorry to hear the news Christy, hopefully you find the cause real soon
![]() If you find any sundial snails, don't nuke'em, as I would gladly take them off your fins.

![]() I had something similar happen. Small patches of zoos would disappear every once in a while. I suspected the Lemonpeel Angel although I never actually saw it eat anything. Now, I feel that I was wrong. Small patches of my zoos continued to disappear and a few nights ago, I found that a few large hungry bristleworms were eating them. I saw one smother a polyp and then a few minutes later to my surprise, I see barren rock. This is one of the reasons why I want to get rid of my hundreds of bristleworms. I use to have an autofeeder but have removed it due to overfeeding. I think the starving bristleworms are now eating whatever they can find that is defenseless. They dont eat all of the zoos, just the ones that had been damaged such as the ones that I had accidentally squished. While eating those, other surrounding ones get damaged and they eat those and so on and now I have a large section of rock where many orange zoos use to be.

![]() 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. |
