YAY you have a pet snail!
When they're so little, it's hard to tell what they are. I initially voted against land snail b/c it's so teeny, but I've never seen a juvie land snail, so they must be a solid color & unobtrusive.
I went camping in the Pamona area outside LA once- it rained & a million huge snails appeared out of nowhere, like a horror movie! I thought I would be eaten alive if I slept too long. They were beautiful & and had differing colors & stripes. I wish I could have captured some & kept them in a terrarium. Here in New England (where I live) you rarely see a land snail; we're slug central (not enough calcium in the "soil"). If you'd like a pet slug, too, I can hook you up ;0)!
4 bettas: Butch, 3-year-old violet male PK EE & 3 girls in a 30 gal sorority. I do not name the girls anymore! 1/2 of them die within a month.
30 gal: 9 Oto cats, 4 Ocellifer cats. Inverts: Cherry shrimp & 2 assasin snails.
10 gal.: Butch, his 5 oto cats, 3 assasin snails, and a few snails the assassins haven't caught.
