The knobbed tower snail ( Tarebia granifera ) is a snail from the family of crown snails (Thiaridae) within the order of the Sorbeoconcha .
features
Tarebia granifera owes its name to the shell covered with knobs (from granum (Latin) = grain). The shape of the knobs varies, possibly depending on the hardness of the water , i.e. the lime content of the water. It is more compact than the much better known Malay tower snail ( Melanoides tuberculatus ).
Multiplication
The knobbed tower snail reproduces parthenogenetically like other crown snails (Thiaridae) .
distribution
Their natural range extends from southern India over the Himalayan foothills to Vietnam and the Malay Archipelago . In addition, this species was introduced by humans in areas of Africa and the Caribbean . There it is a neozoon that is spreading explosively and successfully displacing native species of freshwater snails.
Similar species
In Asia there are other, very similar species with possibly overlapping distribution areas, such as Tarebia lineata . It is currently unclear how many species the genus Tarebia actually includes (around 5) and how these can be differentiated from one another.
Aquaristics
Keeping them in the aquarium is unproblematic, as is that of the needle crown snail . A cross between the two species, which belong to different genera, is not possible. The knobbed tower snail is also diurnal and likes to cover long distances in the aquarium. These "hikes" are not dependent on a deterioration in water quality.
