Helostoma

Kissing gouramis, also known as kissing fish or kissers (Helostoma temminckii), are medium-sized tropical freshwater fish comprising the monotypic labyrinth fish family Helostomatidae (from the Greek elos [stud, nail], stoma [mouth]). These fish originate from Mainland Southeast Asia, the Greater Sundas and nearby smaller islands, but have also been introduced outside their native range. They are regarded as a food fish and they are sometimes farmed. They are used fresh for steaming, baking, broiling, and pan frying. The kissing gourami is a popular aquarium fish.
