looks like it may be one - I am horrible with pictures - but to find out watch and see if it buries itself inyour sand bed. That or put a piece of shrimp right buy it and see if it goes for it ... not all that scientific but Nass. snails love to bury themselves in the sand and will hop on anything dead!
ypu they look exactly like the ones i have... i love them but i only see them at night and when i feed my tank but they do a good job keeping my sand cleen

Karajay---I almost posted in that thread you are talking about. Mine aren't nothing like yours or theirs grrr. I ordered them from here and there's no snout! Definately confused now! At least they aren't doing any damage---lazy---must be nocturnal, and that is iffy.
I only have two nassarius that survived my substrate change! Im ordering 25 more from a friend in the US who will ship (also getting 20 scarlets, 25 turbos etc), they are a great and entertaining addition to the tank.
