The gourami or gouramis are a family, Osphronemidae, of freshwater perciform fishes. The fish are native to Asia, from Pakistan and India to the Malay Archipelago and north-easterly towards Korea. The name "gourami" is also used for fish of the families Helostomatidae and Anabantidae. "Gouramis" is an example of a redundant plural. Gourami is already plural, in its original language.

Many gouramis have an elongated ray at the front of their pelvic fins. Many species show parental care: some are mouthbrooders, and others, like the Siamese fighting fish (Betta splendens), build bubble nests. Currently, about 90 species are recognised, placed in 4 subfamilies and about 15 genera.

The name Polyacanthidae has also been used for this family. Some fish now classified as gouramis were previously placed in family Anabantidae. The subfamily Belontiinae was recently demoted from the family Belontiidae. As labyrinth fishes, gouramis have a lung-like labyrinth organ that allows them to gulp air and use atmospheric oxygen. This organ is a vital innovation for fishes that often inhabit warm, shallow, oxygen-poor water.

[edit] As food

Canned, fried gourami are available in China, and throughout the world in oriental supermarkets. Which species the can contains is uncertain, however, the illustration on the lid of the can depicts the moonlight gourami, Trichogaster microlepis.

[edit] In the aquarium

Gouramis, particularly the tri-spot and dwarf, are often kept in home aquariums. Though often considered peaceful, they can kill almost all other smaller or long-finned fish. However, this usually does not apply to the common types as mentioned above. When they are aggressive, they shred other fishes' fins to the point that the victim can not swim and thus dies. The males of many members of this family like to spar, thus caution must be taken when keeping males together. Aggression can also occur when the fish are too crowded, and they compete for the available space.

[edit] Compatibility

Depending on the species, male gouramis may be fin nippers and may bother other fish in the tank.

In some species, when two males are put in a tank together they will fight constantly. Other, more peaceful, gouramis may show mild to moderate signs of aggression, but are usually able to live together. Male gouramis will ignore many species, such as danios, mollies, silver dollars, and plecostomus catfish, but will often show aggression toward species with long, flowing fins like male guppies and bettas, because they display a long tail and bright colors, presenting competition for impressing a female gourami. Female gouramis do not bother other fish and usually keep to themselves.

[edit] Species

There are about 96 species in 15 genera.
