Description
The popular ramshorn snails kept in aquariums are often referred to as Planorbarius corneus. However, they are probably generally Planorbella (or Helisoma) species originating from the American continent.
The ramshorn snail native to Europe, Planorbarius corneus, probably only rarely finds its way into tropical aquariums. It is likely suitable for cold-water aquariums. This large aquatic pulmonate snail is dark brown and grows larger than Planorbella species; it has planispirally coiled shells measuring up to approximately 4 cm in width and 1.2 cm in height.
Planorbarius corneus is an extremely common aquatic snail in Central Europe. It can be found, for example, in pools, ponds, ditches and slow-flowing waters.
