The snail is a predator of zoanthids and whenever people describe this slow die off it is worth checking for it.
However if your water quality was terrible when you added the corals, well that might have been the problem.

I was just reading your problem, just a question, do you use ro water or tap. If it's city water thy flush out every so often and put more additive in the water which your coral differently would not like. :thinking:

ok, I'm gonna go off the wall so everyone go ahead and bash me, but I know of several cases where you don't want urchins in there. I think the temp thing is a little too easy.

nah, some urchins will hurt corals, many wont though. Sometimes it depends on the urchine istelf and how much it wants camoflauge. or if it just goes over the rocks and your zoos happen to be in the way. Their teeth are like grinders and im sure youve seen by the trail of white rock it leaves.
it could definatly be the temp if this happened over the period of a few months
or even the cleaner shimp. some cleaners and pepermints have been known to attach the zoos, however most will not
i believe that sundial snails, fire worms, ect are a definate possibility. i have noticed that one of my patches of zoos seemed to be receeding. I had found a small snail that looked liek asundial a few months ago, but i squished it. every night i look in my tank to make sure everything is well and i dont have any hitchickers. in that time ive seen random crabs, a pistol shrimp, the sundial snail i was tlaking about, tons of different hitchickers. But as it turns out, the other night when i was looking, i found my CBS eating a softcoral eating bristlewrom. The sides were all furry and everything. I had never seen one in my tank, and i ahvent seen any bristleworms in at least a few months. So it jsut goes to show you that thigns can come up.

Sundial Snail
Another problem that is mostly invisible: zoanthid eating nudibranchs. These nudibranchs eat the zoanthids (and the colorful zooxanthellae they contain) and then turn color to match EXACTLY the zoanthids they are eatting. It is almost impossible to see these things.
I did a freshwater dip on a colony of zaonthids that had been slowly declining in a tank at the LFS and at least 50 nudibranchs fell off. A month later the colony looks GREAT!

You'll have to do a search but there are plenty of pictures of them out there.

i have an Ro/Di unit. The shrimp and urchins are fine! the urchins only stay oin the glass, and the shrips stay in their little caves and only come out to clean a fish or for food.
