Snail with no shell

I believe my margarita snail abandoned his shell and is now crawling along my rocks and such doing what snails do? It's looks like a black loogy with antenie poking around. Is that what it is I haven't seen the snail otherwise? If it is him why did he leave his shell? And is that safe for him ?

 

Are you sure it's not a Stomatella snail instead?

Honestly I do not think a snail leaving it's shell is a good thing at all, could a hermit have ripped it out?

 

Pretty sure it's the margarita cause I only have him a yellow turbo and a snail that lives under the sand unless it's feeding time. And no clue at all I noticed one day that his shell was in the sand bed upside down and he wasnt in it and now I see this black blob on my rocks moving around lol

 

Stomatella snails usually hitchhike in on rocks, corals, or macro algae.
Might also be a scutus.

Google "black stomatella" and "black scutus" and see if it's either of those.

 

+1 to both of the ladies,sounds like you have a stomatella and if so it's a good thing!

 

Ah yes I googled it an that's what it looks like. Just weird it took so long for him to show up havent added rock in almost a month but thank you all!

 

so the real question is where did the snail go! haha =) gratz on your find

 

I'm sure it died I have lost 2 so far in the 4 months since I started my tank.
