Who eats ricordea and zoo's

[cag]

found little tiny snails last night. They have a checkered pattern in them, and they seem to come out mostly at night. I pulled about 30 of them out last night. Could these be the problem? They weren't actually on any coral, just the rocks.

Can you post a picture of the snails? It sounds vaguely like a snail I have in my cube tank, in which I've been unable to keep any kind of coral in the last 6-8 months because they just disappear. However I thought it was the crabs that are in there (I have like 8 or 9 hitchhiker crabs, they're too fast to be caught .. )

Anyhow, crabs and some cowries aren't necessarily innocent either. You might have crabs in that tank and not know it, it took me 6 months after buying the rock before I started seeing them come out regularly. The thing that annoys me the most is that I inspected each and every rock closely for crabs in holes before putting it in the tank ... they were obviously very deep inside or maybe they were larval and somehow survived the shipping.

Is this: http://www.oregonreef.com/sub_worm.htm What that worm looked like? If so, then as it's says in the link, there's your problem!

Followed the instructions, it still doesn't pull the picture into the thread. Not sure what I am doing wrong. Sorry.

How do you get rid of these, if they are the enimy. They are small and hard to get out by hand.

You have to get the address of the uploaded image. The link you've got is the address of the page that shows the image. If you right-click on the picture itself, there should be a "Copy image location" or "properties" tab, eventually you should be able to find something like like http: //www.canreef.com / blah-blah-blah / blah-blah-blah.jpg. Copy that and put it in between [ img ] and [ /img ] tags. (Hope this helps..)

Anyhow though, those don't really look like sundial snails to me. They could be baby trochus. Here's a page that shows what sundials look like:

I'd guess the snails you have to be Collonista Snails. Harmless algae grazers that many reef aquarists will get as hitchhikers at some point.
