The fish in the Anabantoidei suborder are known as anabantoids or labyrinth fish, or colloquially as gouramies (which more precisely refers to the family Osphronemidae). Some labyrinth fish are important food fish, and many others, such as the Siamese fighting fish and paradise fish, are popular as aquarium fish.
In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The muscles on the sides of the pharynx push the oxygen-depleted water out the gill openings. In bony fish, the pumping of oxygen-poor water is aided by a bone that surrounds the gills called the operculum. [6]
The Anabantiformes / æ n ə ˈ b æ n t ɪ f ɔːr m iː z /, is an order of bony fish proposed in 2009. [1] They are collectively known as labyrinth fish, [4] are an order of air-breathing freshwater ray-finned fish with two suborders, five families (Channidae, Aenigmachannidae, Anabantidae, Helostomatidae, and Osphronemidae) and at least 207 species.

The majority of amphibians — except the order Gymnophiona , which are mainly terrestrial burrowers — have a fully aquatic larval form known as tadpoles, but those from the order Anura (frogs and toads) and some of the order Urodela (salamanders) will metamorphosize into lung-bearing and sometimes skin-breathing terrestrial adults, and most ...
Tubifex are raised commercially, mainly for fish food: the reddish Tubifex tubifex. Tubifex can be easily cultured on mass scale in containers with 50–75 mm thick pond mud at the bottom, blended with decaying vegetable matter and masses of bran and bread. Continuous, mild water flow is to be maintained in the container, with a suitable ...
A member of the Cyprinidae, carp spawn in times between April and August, largely dependent upon the climate and conditions they live in. Oxygen levels of the water, availability of food, size of each fish, age, number of times the fish has spawned before and water temperature are all factors known to effect when and how many eggs each carp ...
The climbing perch (Anabas testudineus) is a species of amphibious freshwater fish in the family Anabantidae (the climbing gouramis).A labyrinth fish native to Far Eastern Asia, the fish inhabits freshwater systems from Pakistan, India, Bangladesh and Sri Lanka in the west, to Southern China in the east, and to Southeast Asia west of the Wallace Line in the south.
Gouramis, or gouramies / ɡ ʊ ˈ r ɑː m i /, are a group of freshwater anabantiform fish that comprise the family Osphronemidae. The fish are native to Asia—from the Indian Subcontinent to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and ...
