Betta
''Betta'' is a large genus of small, active, often colorful, freshwater ray-finned fishes, in the gourami family (Osphronemidae). The best known ''Betta'' species is ''B. splendens,'' commonly known as the Siamese fighting fish and often kept as an aquarium pet. Characteristics All ''Betta'' species are small fishes, but they vary considerably in size, ranging from under 2.5 cm (1 in) total length in ''B. chanoides'' to 14 cm (5.5 in) in the Akar betta (''B. akarensis''). Bettas are anabantoids, which means they can breathe atmospheric air using a unique organ called the labyrinth. This accounts for their ability to thrive in low-oxygen water conditions that would kill most other fish, such as rice paddies, slow-moving streams, drainage ditches, and large puddles. The bettas exhibit two kinds of spawning behaviour: some build bubble nests, such as ''B. splendens'', while others are mouthbrooders, such as ''B. picta''. The mouthbrooding species are sometim ...

Siamese Fighting Fish
The Siamese fighting fish (''Betta splendens''), commonly known as the betta, is a freshwater fish native to Southeast Asia, namely Cambodia, Laos, Myanmar, Malaysia, Indonesia, Thailand, and Vietnam. It is one of 73 species of the genus ''Betta,'' but the only one Eponym, eponymously called "betta", owing to its global popularity as a pet; ''Betta splendens'' are among the most popular aquarium fish in the world, due to their diverse and colorful Morphology (biology), morphology and relatively low maintenance. Siamese fighting fish are endemic to the central plain of Thailand, where they were first domesticated at least 1,000 years ago, among the longest of any fish. They were initially bred for aggression and subject to gambling matches akin to Cockfight, cockfighting. Bettas became known outside Thailand through King Rama III (1788-1851), who is said to have given some to Theodore Cantor, a Danish physician, zoologist, and botanist. They first appeared in the West in the lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betta Picta
The spotted betta or Java fighting fish (''Betta picta'') is a species of gourami endemic to Indonesia where it inhabits relatively cool, 22‒25 °C (72‒75 °F), highland streams of Java and Sumatra. In 1967, D. S. Johnson reported the species to be common in blackwaters of southern Malaya. Of largely unremarkable ''Betta'' appearance, ''B. picta'' attains an overall length of 6 cm (2.4 in). It is noted for the pale bars on the male's back, absent in other similar ''Betta'' species. Mouthbrooders, spotted bettas spawn ''en masse'' when triggered by water changes; this is likely to be an adaptation to reduce the chances, by saturating the environment with young, of individual fry falling prey to predators. This betta spawns readily and prolifically in captivity, producing easily raised fry. Even though it is easily kept and bred, it is not one of the more popular ''Betta'' species among hobbyists, likely because, in the words of one ''B. picta'' ...

Penang Betta
The Penang betta (''Betta pugnax'') is a species of gourami native to Southeast Asia and common in swiftly flowing forest streams of the Malay Peninsula, Thailand, Sumatra, and the Riau Islands. In addition to its native range, the species has been introduced to Guam. It can be found amongst the vegetation growing along the banks. This species can reach a length of SL. It is one of the mouthbrooding ''Betta'' species. This species, as a natural predator of mosquito larvae, has found use in mosquito control efforts.

Betta Miniopinna
''Betta miniopinna'' is a species of gourami endemic to Bintan Island in the Riau Archipelago of Indonesia.

Betta Persephone
''Betta persephone'' is a species of labyrinth fish endemic to Malaysia where it is only known from Johor.

Description ''Betta persephone'' is a small species with a maximum length of SL. The males are largely blue-black in colour, with the females exhibiting browner tones. Distribution and habitat ''Betta persephone'' has a limited distribution in Malaysia, the type locality being Ayer Hitam in Johor. This ''Betta'' species inhabits soft, acidic waters at temperatures of 23‒28 °C (73‒82 °F). The typical habitat is closed-canopy forest where it is dark on the forest floor and there is thick vegetation on the banks of the blackwater streams and peat swamps where this fish lives among submerged tree roots. Sometimes it may be forced to live temporarily among the wet leaf litter in periods when the peat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gourami
Gouramis, or gouramies , are a group of freshwater anabantiform fishes 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 Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. All living species show parental care until fry are free swimming: some are mouthbrooders, like the Krabi mouth-brooding betta (''Betta Simplex''), and others, like the Siamese fighting fish (''Betta splendens''), build bubble nests. Currently, about 133 species are recognised, placed in four 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 fishe ...

Mouthbrooder
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
