Tarebia granifera, common name (in the aquarium industry) the quilted melania, is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Thiaridae. This snail is native to south-eastern Asia, but it has become established as an invasive species in numerous other areas.

Subspecies of Tarebia granifera include:

A detailed account of the anatomy of Tarebia granifera was given by R. Tucker Abbott in 1952 together with notes on its biology and bionomics. A dissection guide was provided by Malek (1962).

The maximum height of adult shells of this species from South Africa is from 18.5 mm to 25.1 mm, while in Puerto Rico they can reach up to 35 mm.

Two color forms of Tarebia granifera exist, one has a pale brown body whorl and a dark spire (see photo on the right) and in the other the shell is entirely dark brown to almost black (see photo on the left). Intermediate forms exist.
