    Noticed this little guy crawling on a piece of monti cap. Don't recall ever seeing him before and just curious if anyone can help ID as good or bad!

    Yeah, there are people better than I that note if it is a left or right shell and all the others, but that is my best thought. Any recent adds? Mine spend a good portion buried in the sand and come out at night...

    Hopefully a helpful part of your CuC

    Just added a little bit of live sand last week to top off the sand bed. Just noticed a different kind of snail on my shrimps molt. Hope he made out ok with the molt, l helped him out of it because snails were pouncing on him lol. Never noticed all these small snails before. Wonder if there was some reproduction or something t occurring in the tank...:

    I took a few better pictures. I don't think they're cerith snails based on their long proboscis

    Certainly some sort of whelk. A good whelk or a bad whelk is TBD...

    Is there any kind of snail that eats SPS? I can almost attribute the appearance of these snails to the beginning of the demise of a large monti cap, and I've seen them hanging out on my green slimer / orange cap which don't seem nearly as happy as they used to.

    Bad whelks tend to eat clams and other snails not sps coral.

    Hmm ok. I can't figure out why some of my sps seem less than thrilled recently. Haven't changed a thing and only recently began noticing those snails after adding a 10 lb bag of "live sand" the other day

    I would pull one out and photo in glass container. Then check with #lionfishlair. If welks I would remove.

    I checked the lionfish lair website and couldn’t really find anything that matched. @reef lover seems certain they are whelks. So I’ll just be safe and start pulling them out when I see them.

    If they’re whelks, is it possible they would have killed a cleaner shrimp who had molted?

    Narrcissarous sanils are in the whelk family. Hence good whelk bad whelk. I've seen black nars. Before.put them in the sump if your unsure about them. I've read where u can tell the difference if you can see the eyes at the base of the two front tentacles they're nars. But I've never been able to confirm this.
