I recently set up a ten gallon planted tank, with a few cherry shrimp. Along with the plants came ~3 of these little snails. I threw one away that looked an awful lot like a ramshorn snail (bane of my existence!) But the other two look like the one pictured. They appear to eat algae, since I can see little paths through the algae on the glass. Neat lookin critters that's for sure.
