Lays eggs in fresh water, but the larvae need brackish or sea water, so it won't multiply in your tank.
Full breeding guide, day-by-day plan and simulator →A euryhaline nerite from coastal mangroves and streams that also lives far inland in pure fresh water; an eager grazer of algae films that tends to climb out of an uncovered tank.
Carl Linnaeus described this snail in 1758 in the famous 10th edition of Systema Naturae. Its warm orange-brown shells earned it the trade name 'sunset nerite'.
First described by Carl Linnaeus in 1758.

Accepted name in MolluscaBase. Aquarium Glaser notes the same snails reach the trade under other names (Neritina coromandeliana, N. turrita colour form, N. variegata); the trade name "sunset nerite" is not tied to one species, so identity of shop snails is uncertain. MolluscaBase flags the species as terrestrial (isTerrestrial=1), reflecting its amphibious habits.
MolluscaBase (via WoRMS): Neritodryas cornea (Linnaeus, 1758), AphiaID 850635Legacy has no family; recorded as sourced.
MolluscaBase (via WoRMS): Neritodryas cornea (Linnaeus, 1758), AphiaID 850635No species figure found. Genus Neritodryas: shell up to 40 mm (Wikipedia citing Symonds & Pacaud 2010), so legacy 3 cm is plausible but unconfirmed.

Exact species range not found in one source; pieced together from Haynes (Oceania genus account) and Glaser (Thai imports). Note Haynes attributes the names to authors differently from MolluscaBase.

Aquarium Glaser (German wholesale importer; Frank Schäfer), 18 May 2020: Neritodryas corneaLegacy says it "does best with a little salt"; Glaser advises ordinary not-too-soft fresh water at about pH 7. Shell colour claim (browns and reds) not checked.
