The croaking gourami (Trichopsis vittata) is a species of small freshwater labyrinth fish of the gourami family. They are native to still waters in Southeast Asia and are distributed worldwide via the aquarium trade. Croaking gouramis are capable of producing a "croaking" noise using their pectoral fins.

In the wild, croaking gouramis are mostly insectivorous, feeding on insects and insect larvae, however other food types, such as zooplankton, crustaceans, shrimp meat and occasionally plant matter, are eaten as well. In aquaria, a varied diet is important to their long-term health; standard flake foods along with regular supplements of freeze-dried bloodworms, tubifex worms, brine shrimp, and some algae-based flakes will provide these fish with proper nutrition. Occasional feedings of live brine shrimp offer the aquarist an opportunity to observe the natural hunting behaviour of croaking gouramis.
Sex can be most reliably determined by candling but the more common approach is to observe the shape of the dorsal fin: the male's dorsal fin is pointed, while the female's is rounded. The male croaking gourami is a bubblenest builder, creating a small nest from air bubbles and mucous under a leaf. The water level should be reduced to 8 inches during spawning, circulation kept minimal, and the temperature should be approximately 28 °C (82 °F). Spawning occurs under the nest, with the female responding to the male's dance by rolling over, followed by the typical gourami embrace. About 5 to 10 eggs are released in a quick burst. The male will grab the eggs and spit them into the nest, often adding a few more bubbles for good measure. This act may be repeated a dozen times or more, until about 100 eggs are laid. Some large females may lay more than 200. After spawning the female should be moved to a different tank. The male will keep the bubblenest maintained and tend to the eggs and fry, but when the fry are 2–3 days old the male should also be removed. When first hatched, the fry should be fed infusoria, and later, baby brine shrimp and finely ground flakes. Freeze-dried tablets may also be fed to older fry. It is important that the breeding and grow-out tanks be covered and protected from cool drafts, as low air temperatures above the water surface may cause damage to the developing labyrinth organs of the young fish when they begin to take gulps of air.
