Helostoma temmincki

The kissing gourami is a near relative of the Belontiidae - it actually belongs to the family Helostomatidae - and like them possesses a labyrinth, and builds a bubblenest for its eggs. The "kissing" behavior observed between individuals probably has some social function; it is not necessarily linked to reproduction, though admittedly also occurring during the mating ritual. Size: 10-15 cm.
