In Ohio (where Art resides), the aquarium Ramshorn is usually either
Planorbella trivolvis (Say, 1817) (which, while native to the area,
probably came from somewhere else) or the exotic Marisa cornuarietis
(Linneaus, 1758). Trivolvis is a smallish, brown snail (maybe to 3/4 inch)
whereas Marisa is large (1.5-2 inches), usually boldly striped. Marisa is
actually an atypical ampullariid. Trivolvis usually ends up in your
aquarium from purchasing aquatic plants - most shops don't sell trivolvis.
Marisa is usually sold as an aquarium specimen. Albino Marisa are popular
and are golden in color. Marisa is from Central and South America.
