The pygmy gourami (Trichopsis pumila), also known as the sparkling gourami, is a freshwater species of gourami native to Southeast Asia.

Pygmy gouramis can reach a length of 4 centimetres (1.6 in) SL. In color, they sparkle with red, green, and blue hues, and can produce an audible croaking noise using a specialised pectoral mechanism. In the right light, its eyes appear bright blue, and its arrowhead-shaped body and caudal fins reflect a rainbow of colors as it swims. Sexing is difficult, but males have red spots above the "body line" or the stripe through their body, and females spots are duller.

Its native habitat is slow rivers, rice paddies, ditches and small ponds. It is most commonly found in standing not stagnant water (including waters with low oxygen levels) that has a dense cover of floating plants. The pygmy gourami can survive in these waters because of its labyrinth organ, which allows it to breathe air from the surface. Its native habitat has a pH of 6.0 - 7.5, dH of 5 - 19, and temperature 25°C to 28°C (77°F to 83°F). It feeds on zooplankton and aquatic insects.

The pygmy gourami can be found in the aquarium trade.

The pygmy gourami is hardy and tolerant of less-than-ideal water conditions in the tank. It is important to avoid any strong currents in the aquarium and need plenty of hiding places; a heavily planted tank with subdued lighting would be ideal. They require some space between the top of the water and the tank cover from which to gulp air. Preferred water conditions include a temperature of 25°C (76°F) or above, and a pH of less than 7.

While these are not schooling fish, they can usually be kept peacefully in small groups. Keep in mind that they will not compete well for food with aggressive tankmates, nor will it cope well with constant harassment. Notoriously nippy fish such as tiger barbs or large danios are poor choices for tank companions. Because of their small size, pygmy gouramis are an ideal choice for smaller aquaria. They will be targeted by male Bettas so they should not be kept with them.
