hi, unfortunately i cant get a pic on here yet but i have bean given this snail and bit worried it is a predatory one. it is about an inc long has a long thin opening from the shell. it has a foot that it can push its self up with very rapidly and a long proboscis that it can push out. it has well developed eyes that look like they have something like an iris. its a dull gray brown and yellow inside of shell that looks like a comb pattern. im conserned as when i put my hand near it it shot its proboscis out and jumped up. i have seen it watching the fish very keenly too. i have seen nature programs with similar shaped foot and proboscis that eat fish and have a poisoned harpoon. the shell pa tern is not the same thow. ill see if i can post a pic of it
