I've noticed a couple of these over the last week or so they move around like a snail. I haven't been able to get a good pic of them until I got some good advice from Lee (Tulsa Reefer), THANKS A LOT! Anyway I haven't been able to find pics on the net to I.D. them. So give me your opinions.

They look like stomatella snails to me.I love these snails as they multiply well and do a decent job.PLUS there freeeeeeeeeeeeeeee!

Yep, looks like black Stomatella. I have tan ones in my smaller tank, and they breed like bunnies if there aren't any shrimp or crabs to prey on the smaller ones. I think they will still breed even with predators, just won't build up quite a quickly. Check after dark, they really seem to come out on the glass after the lights are out.

And the pics are looking really good! Glad it's working out.
