Gouramis or gouramies (i) [go rɒm ee] are a group of freshwater perciform fishes that comprise the family, Osphronemidae. The fish are native to Asia, from Pakistan and India to the Malay Archipelago and north-easterly towards Korea. The name gourami, of Javanese origin, is also used for fish of the families Helostomatidae and Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. Gouramis belong to the family Osphronemidae and are so called labyrinth fishes. To survive in waters low in oxygen, they swim up to the surface and breathe oxygen directly from the air. This is possible since they have a labyrinth shaped organ capable of utilizing oxygen from the air.  In the wild Betta Fish seldom survive for more than a year or two. However, when they’re bred in captivity and are kept in ideal conditions Betta Fish can live anywhere up to 2-4 years. Betta fish have a labyrinth organ, a unique adaptation that allows them to breathe air at the water’s surface when their water becomes oxygen depleted. Bettas are members of the gourami family (Osphronemidae) of the order Perciformes, although they were formerly classified among the Anabantidae. There are nearly 50 other members of the Betta genus, but Betta splendens is the species we focus on as aquarists. White spots extend on to the fins, giving them a very attractive pattern. 1  Size of fish-inches: 5.9 inches (15.01 cm) - They can reach almost 6 (15 cm), but are usually a bit smaller in the aquarium. 2  Lifespan: 4 years-The average lifespan is 4 - 6 years, but with proper care they can live longer. They will be able to breed at about 3 inches (7.5 cm). They have an average lifespan of 4 to 6 years, but can live longer with good care. The body color is a pretty gold tone with a deeper toned striped patterning along the back. The two dark spots seen on the Three-spot Gourami are absent. Gouramis, particularly the three spot and dwarf, are often kept in home aquaria. As labyrinth fish, they will often swim near the top of the tank. As with other tropical freshwater fish, an aquarium heater is often used. Gouramis will eat either prepared or live foods. Some species can grow quite large, and are unsuitable for the general hobbyist. The fish are native to Asia, from Pakistan and India to the Malay Archipelago and north-easterly towards Korea. The name gourami, of Javanese origin, is also used for fish of the families Helostomatidae and Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. Betta Fish, or Siamese Fighting fish. are found mainly in the southern parts of South-East Asia, and are especially abundant in Vietnam, Thailandand Cambodia, where they thrive in in reedy ponds, slow moving creeks and rivers. Bettas are members of the gourami family (Osphronemidae) of the order Perciformes, although they were formerly classified among the Anabantidae. There are nearly 50 other members of the Betta genus, but Betta splendens is the species we focus on as aquarists. Gouramis. The Gourami family, Osphronemidae, stems from the freshwater perciform fishes. They are native to Asia, from Pakistan and India to the Malay Archipelago and further north-easterly towards Korea. The name “gourami” is also used for fish of the families Helostomatidae and Anabantidae. Just for interest sake, the plural “Gouramis” so commonly used among aquarists, is an example of a redundant plural. ON EXHIBIT: River Giants exhibit in River Journey. Giant Gouramis are the largest fish in the family Osphronemidae, which includes many smaller varieties of gouramis including pearl gouramis, which can be found in our Tropical Asian Rivers exhibit in Rivers of the World.  However, they can be paired with other fish. These species are native to the Mekong basin of Laos, Cambodia, Vietnam and Thailand, the latter formerly known as Siam. The fish can be found in standing waters of canals, rice paddies and floodplains. In January 2014 a large population of the fish was discovered in the Adelaide River Floodplain in the Northern Territory, Australia. As an invasive species they pose a threat to native fish, frogs and other wildlife in the wetlands.
