Hi all,

Looks like pond snails for the larger two and ramshorn for the little one!

Definitely look like Pond Snails, Tadpole Snails (Physella) would have a wider basal whorl, but they look pretty similar when they are small. If you want to be sure, via Wikipedia:

Physella are quite distinctive, because they have shells that are sinistral, which means that if the shell is held such that the spire is pointing up and the aperture is facing the observer, then the aperture is on the left-hand side."

The Ramshorn looks like a Keeled Ramshorn, does it have a central ridge on the outer whorl?
