Anyone Know What This Is??
 

I noticed something small and black back a month or so.....but it ducked into the rocks. Now its larger and seems to have a different style shell than the other snails I have seen.

Anyone know what this is?

how small is small? go look up stomatella snails... i think that's what we're looking at.

I can't tell for sure from the picture. Does it look like this?

i have one of those in my tank from that link maybe he's my problem with eating zoa's =(

Justinl, that could be it. Mine has a shell like these....the ones I seen on the web were not black, but I am sure there are lot of varieties.

He looks like a slug....but a half shell covering. He is approx 1/4" wide and 1/2" long......if this is the same one (maybe there are more!) he was 1/4 of this size a month ago.

Xtreme he looks a lot like this, but I think my guy has a shell. (Like a 1/2 shell on top) Its had to tell as he is a matte black color all over.....hard to see where one end starts and ends.

They have flaps of skin that cover the shell. Sometimes it is visible though.

im pretty sure its a keyhole limpet. sometimes it will have a white patch on its back. They are harmless.

Stomatella, not elephant slug. You can tell by the tentacles extending from the mantel. They're like a mini-abalone. Harmless, beneficial algae eater that will reproduce readily.

That's a Stomatella, they come in the basic brown color and this black color. I have both kinds. They are my favourite snail, plus they are one of the few that successfully reprocude in our tanks. :)
