The three spot gourami (Trichopodus trichopterus), also known as the opaline gourami, blue gourami, and gold gourami, is a species of fish native to southeastern Asia, but also introduced elsewhere.[1] This gourami gets its name from the two spots along each side of its body in line with the eye, considered the third spot.[3] This species is of minor commercial importance as a food fish in its native range and is also farmed. It is also popular in the aquarium trade.[2] The species reaches 15 cm (5.9 inches) in standard length.[2]
