Knowra Gourami Gourami Gouramis are freshwater fishes in the family Osphronemidae, native mainly to Asia and Africa. Many species breathe atmospheric air with a labyrinth organ and are popular aquarium fish.
Osphronemidae : A family of freshwater fishes that includes gouramis and bettas. Gourami is the common name for multiple members of this family.
Dwarf gourami : A small, brightly colored gourami species, Trichogaster lalius, native to South Asia. It is one of the most common gouramis kept in home aquariums.
Bubble nest : A floating cluster of air bubbles coated with mucus, built by some fish as a spawning site. Several gourami species build nests where their eggs develop near the surface.
Betta : A genus of freshwater fishes in the gourami family, including the Siamese fighting fish. Bettas share the family’s labyrinth organ but differ in body form and typical aquarium behavior.
Labyrinth organ : A specialized breathing structure that lets some fishes take oxygen directly from air. Many gouramis use this organ to breathe at the water’s surface.
Pearl gourami : A Southeast Asian gourami, Trichopodus leerii, marked with pale pearl-like spots. Its distinctive pattern and generally peaceful behavior make it a popular aquarium species.
Fish reproduction : The biological processes by which fish produce offspring. Gourami courtship, spawning, and parental care are forms of fish reproduction.
Paradise fish : Macropodus opercularis, an East Asian labyrinth fish in the gourami family. It is a close relative with a more pronounced reputation for territorial aggression.
Anabantoidei : A suborder of ray-finned fishes that includes gouramis, bettas, and paradise fish. This broader group places gouramis among other labyrinth fishes.
Three-spot gourami : A Southeast Asian gourami, Trichopodus trichopterus, with two dark body spots and an eye that forms the third. Aquarium color varieties of this adaptable species are widely sold.
