These guests of our aquaria lay their eggs as a jello like mount, generally on the aquarium glass but plants also seem to be a choice for egg-laying.

In their natural habitat, they have a preference for slow moving rivers or dormant water marshes.  Among some twenty species known in Central Europe, Biomphalaria Glabrata has a shell size that varies from 2 to 3 cm.
