Trichopodus

Trichopodus (formally Trichogaster ) is a genus of tropical freshwater labyrinth fish of the gourami family found in Southeast Asia. Gouramis of the Trichopodus genus are closely related to those of Trichogaster (formally Colisa), species of both genera have long, thread-like pelvic fins (known as "feelers" in the aquarium trade) used to sense the environment. However, Trichopodus species have shorter dorsal fin base and, when sexually mature, are much larger, with the largest, the snakeskin gourami (T. pectoralis), capable of reaching a length of over 8 inches.

Along with the Trichogaster species, Trichopodus gouramis are popular in the aquarium trade. The three spot gourami (T. trichopterus), with its several aquarium variants, each known by a different trade name, is perhaps the most common aquarium gourami. Trichopodus species are also used as food fish in its native range. The snakeskin gourami, in particular, is one of the top five aquacultured freshwater fish in Thailand.
