Features Marisa Cornuarietis
They require a spacious aquarium with filtered and well oxygenated water but cannot be kept in planted aquariums because they will eat the plants. In the aquarium there can be a moderate current of water and in order for the snails to develop harmoniously and reach maximum sizes, the aquarium must be at least 60 cm long.
Although it is a freshwater species, it can also tolerate relatively high concentrations of salt in the water, however reproduction will occur only in fresh water.
Breeding Marisa Cornuarietis
Sexual dimorphism: they are not hermaphrodites but the differences between the sexes are not very obvious. If you look closely at two shells, it will be noticed that the male has a rounder profile and the female, in cross section is less round.
They will lay eggs on plants, under the surface of the water and are covered by a gelatinous matter. The eggs are between 2-3 mm when laid but as the snails develop, they grow up to 4 mm and the young can be seen inside them.
