Betta Fish Care Ebooks
Physical characteristics Siamese fighting fish reach a length of about 2 inches (6 centimeters). They have a long tube-shaped body. Some species have large fanlike dorsal, anal, and tail fins. Wild Siamese fighting fish have a bluish body and blue and red fins. There are two shiny marks on the gill cover. Males have larger fins and are more brightly colored than females. Geographic range Siamese fighting fish live in Southeast Asia and in areas where they have been accidentally released, such as Florida, in the United States. Habitat Siamese fighting fish live in standing water with dense plant life, especially rice paddies and canals. They may dig into the Siamese fighting fish are well known for their aggressive behavior, especially against males in their own species. ( A. N. T. Photo Researchers, Inc. Reproduced by permission.)

Betta splendens Osphronemidae Betta splendens Regan, 1910, Menam River Mae Nam Chao Phraya , Thailand. English Betta French Combatant, combattant du Siam German Siamesischer Kampffisch Spanish Combatiente siam s. This species is well known for its prominently developed aggressive behavior, especially against conspecific males. Confined to small tanks, males fight until one of them is killed. In Thailand, various breeds of Betta splendens are used in popular fighting matches in which people bet on the outcome.
Osphronemidae English Diamond gourami, lace gourami, mosaic gourami French Gourami mosa que, gourami perl German Mosaikfadenfisch Spanish Gurami perla, Gurami mosaico. Length 4.7 in (12 cm). Body laterally compressed with short dorsal fin of 5-7 fin spines and 8-10 soft rays long anal fin with 12-14 spines and 25-30 soft rays. Pelvic fins with an extremely prolonged first soft ray behind the spine, followed by four short soft rays. This pelvic filament reaches up to two-thirds of the fish's total length, is highly movable in all three dimensions, and is used as an organ of taste because its surface is covered with numerous taste buds. A tactile function has also been demonstrated. Males can be distinguished from females by the posterior rays of the soft dorsal and soft anal fin being prolonged and projecting beyond the fin membrane. Coloration of the body consists of a grayish background, with numerous bright white spots all over the body and fins (hence the name pearl gourami), a...
Osphronemidae French Gourami g ant German Riesengurami Spanish Gurami gigante, gurami comestible. Nothing is known about the behavior of the giant gourami in the wild. The giant gourami is omnivorous, feeding on plants, smaller vertebrates, invertebrates, and even dead animals.

The labyrinth fishes were first recognized as a natural assemblage by Cuvier and Valenciennes in 1831, but included the Channidae (snakeheads), in addition to the current family Anabantoidei. Bleeker (1859, 1879) added the luciocephalids (pikeheads) to this group. Jordan (1923) recognized six families, including Luciocephalus and Channidae. In 1963, Liem restricted the anabantoids to the families Anabantidae, Helostomatidae, Osphronemidae, and Belontiidae, thus removing Luciocephalus and the channids. In 1983 Lauder and Liem included Luciocephalus, in its own family Luciocephalidae, again in the anabantoids as the sister group to all remaining labyrinth fishes. Britz (1994, 1995), and Britz et al. (1995) demonstrated that there are no differences between Liem's families Belontiidae and Osphronemidae and that Luciocephalus is deeply nested within Liem's belontiids. The family name Os-phronemidae applies for this monophyletic assemblage. The suborder Anabantoidei is thus divided into...
Some Beloniformes are used by humans as more than just food. Numerous freshwater species, including halfbeaks, rice-fishes, and needlefishes, can be found in the aquarium trade. In Thailand, the halfbeak, Dermogenys pusillus, is bred in captivity so that males, which will engage rivals by locking jaws, can be used as fighting fish. Members of the genus Oryzias are propagated in large numbers in captivity to be used in experimental research.
Anabantoids are diverse in regard to their feeding ecology and diet. There are extreme filter feeders, such as Helostoma, which feeds on small pelagic invertebrates and algae that are either filtered from the water or scraped off the substrate. Other species are omnivorous (Anabas, Osphronemus, Tri-chogaster, and Colisa), or have a diet with an emphasis on small invertebrates (Microctenopoma, Macropodus, Betta, and Trichop-sis), but others prey on larger invertebrates and small fishes (Ctenopoma and Sandelia). Luciocephalus is a highly specialized predator of small fishes. Osphronemus exodon is an exclusively herbivorous species with external jaw teeth, which feeds on leaves of terrestrial plants, grasses, fruits, and flowers.
Although anabantoids are a fairly small percomorph group, their members exhibit a great variety of reproductive modes. The primitive mode, which occurs in Anabas, Ctenopoma, and Helostoma, is the absence of parental care with the release of several thousand small (ca. 0.04 in 1 mm), buoyant eggs that float due to a single large oil globule in the egg. After hatching, larvae retain the oil globule, which during development divides into two oil vesicles to the left and right of the chorda and is used as a floating organ. All species of the genus Mi-croctenopoma and most osphronemids build bubble nests and guard primitively buoyant eggs and larvae. Bubble nests can consist of only a few bubbles, as in the tiny cave-brooding species of Parosphromenus, or be large. Mouth brooding has evolved at least twice among anabantoids, once in the lineage Ctenops, Sphaerichthys, and Luciocephalus, and again within the genus Betta.
