The most distinctive feature of the kissing gourami is its mouth. Other than being terminal (forward-facing) rather than superior (upward-facing) as in other gourami families, the kissing gourami's mouth is highly protrusible as its family name suggests. Spawning occurs from May to October in Thailand
The Kissing Gourami Helostoma temminkii was first described by Cuvier in 1829 and named after a Dutch doctor, Temminck. They are found in the tropical Asia from Thailand into Indonesia in Sumatra, Borneo, Java, Cambodia, Malay Peninsula, and possibly in eastern Myanmar (Burma). This is a monotypic genus that contains only this single species.
