A small group of fishes can be kept together provided ample hiding places are provided. Eggs are released in batches, exhausted over multiple embraces for up to five hours. Betta pugnax can be housed in pairs, species tanks and community tanks. Betta pugnax (Penang betta) Pugnax – in Latin, it means ‘combative’. As with all anabantoids, a layer of air must be kept between the water surface and tank cover as these fish are obligate air-breathers. The United Nations Environment Programme lists an unconfirmed species, Betta cf. obs.). Redescription of the Malaysian fighting fish Betta pugnax (Teleostei: Belontiidae), and description of Betta pulchra, new secies from Peninsular Malaysia. The head is everywhere covered with large rounded scales like the rest of the body, but the slightly protractile jaws are naked; the posterior part of each branch of the lower jaw is covered by a single large oval scale. Of the six branchiostegous rays the upper one is longer and broader than the rest; the fifth and six are rounded, setaceous. ), it is clear that the, clade. Main habitats were shallow (10-80 cm deep), stagnant areas characterized by overhanging bank vegetation and associated roots, and submerged leaf litter. Fins: Pelvic fin length 26.6-43.8% SL; length of anal fin base 44.2-54.0% SL; length of dorsal fin base 9.9-15.7% SL. : Pelvic fin length 26.6-43.8% SL; length of anal fin base 44.2-54.0% SL; length of dorsal fin base 9.9-15.7% SL. For best results remove brooding males or all other fish. Images and content by others should not be used without permission. A cover should be fitted as these fish are excellent jumpers. Betta enisae atteint la taille maximale de 6 cm pour les mâles, mais on notera que les différentes populations de localités différentes ont été observées avec des différences de coloration, les motifs, et dans certains cas, même la morphométrie était variable. comm. Waters were neutral to slightly alkaline, pH around 7.4 (Tan & Ng, 2005). Body is slender with a robust head and usually brown with bluish green iridescent scales. The scales are rather large, higher than long; the anterior margin is straight with 21 striae, the posterior rounded, ciliate; a line from the gill-opening to the caudal fin contains 32; the greatest diameter presents 10. Major Betta clades are denoted by: A - pugnax, B - albimarginata, C - coccina, D - foerschi, E - splendens, F - unimaculata, G - macrostoma. The greatest vertical diameter of the body, at the dorsal spine, is in some individuals 3/4 of, in others equal the length of the head. Les Betta pugnax en vente font entre 6 et 8 centimètres. The caudal is very broadly lanceolate; the two central rays are the longest, in some individuals 1/3 of the entire length of the fish, but frequently less. ), where it inhabits small, fast flowing hill-streams (Lim & Ng, 1990) and larger lowland streams (Lim, 2011, pers. Alfred (1963) designated a complete alcohol-preserved specimen as the lectotype and two formerly dried specimens as paralectotypes. Fish ecology. Le pH de l'eau oscille de 6.0 à 7.0 . Betta pugnax in Singapore Point map ( Betta pugnax ) | Occurrence records | Field guide | Gazetteer | Country Species Summary Main Ref. ; Linke, 1992; Goldstein, 2001).Specimens from Penang typically reach sexual maturity above 40 mm SL, whereas certain populations from Singapore and Johor were found mouthbrooding and displaying adult coloration at smaller sizes (Tan & Tan, 1996).Figure 10. In captive specimens, it has been observed that fights substantially decrease once a hierarchy has been established amongst a group, and subsequently, serious damage rarely occurs (pers. (Illustration: Low Bi Wei)Figure 7. In captive specimens, it has been observed that fights substantially decrease once a hierarchy has been established amongst a group, and subsequently, serious damage rarely occurs (pers. Betta pugnax a été décrit à partir d'une population qui peuple l'État de Penang en Malaisie. By applying different weights for the postulated directionality of changes (from bubble-nesting to mouthbrooding, or vice versa), based on phenotypic and behavioural differences between the two forms of brood care, the recurrent evolution of mouthbrooding is favoured using parsimony, with bubble-nesting as the, refers to a specimen or a group of specimens to which a species (scientific) name is officially attached to. The rays of the latter gradually increases in length to the twenty-third or fourth, which are sometimes elongated beyond the point of the caudal fin. Other suitable tankmates include similar-sized, robust species with a peaceful demeanour, such as rasborines and some of the peaceable barb species . The head is everywhere covered with large rounded scales like the rest of the body, but the slightly protractile jaws are naked; the posterior part of each branch of the lower jaw is covered by a single large oval scale. 1996. If breeding is to be attempted, it is recommended that a pair be kept alone. It will remain concealed in vegetation lining the banks of such streams. (SL), rhombic when viewed from above; green or blue iridescent spots on scales upon a brown body, scales iridescent in males and sometimes extending to the belly; females and juveniles displaying two transverse dark bands converging at a dark spot on the, ; a stout body with body depth 24.8-32.1% of SL, juveniles tending to be the slender with proportionately larger eyes; central stripe on head; occasional dark, lower pre, stripe (chin bar) extending from eye to throat but with no dark marks below central stripe on opercle; mature specimens with pointed, often elongated fins and a broadly, transverse bars; caudal transverse bars only in males (Figure 7); red sub, ; black edge on anal fin but not caudal fin; 25-28. width 32.4-53.0% of head length; lack of broad iridescent patches in iris (Tan & Tan, 1996; Tan & Ng, 2005). The mouth is semicircular, moderate; the angle is in front of the orbit. Rose Tail Betta $ 13.50. The hypothesized evolution of species can be inferred from phylogenetic studies. The length of the anterior filamentous ventral ray rarely exceeds that of the head. As males do not feed while brooding, they should be removed from the spawning tank upon release of fry, to allow for recuperation. 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. The dorsal fin commences a little behind the posterior half of the body; the rays gradually increase towards the fifth, the longest; the extent of the base is from 1/8 to 1/9 of the length of the body; the distance from the last ray to the caudal is 1/4 of the length of the body. Notes on a collection of fresh-water fishes from Penang. Betta pugnax is not listed in the Singapore Red Data Book, nor the International Union for Conservation of Nature (IUCN) Red List. The holotype for Betta macrophthalma was discovered to be a juvenile Betta pugnax, highlighting the historical confusion over the identity and description of the species. (Illustration: Low Bi Wei), Figure 7. The vertical diameter at the root of the caudal fin varies from 5 1/2 to 1/6 of the length of the body. Though some literature recommend the use of soft, slightly acidic water for this species, they are not fussy with water chemistry, being able to tolerate acidic to slightly alkaline water. (Photo: Low Bi Wei) Name Binomial: Betta pugnax (Cantor, 1850) Vernacular: Forest Betta, Malayan Betta, Penang Betta Etymology The species epithet is derived from Latin pugnax, which means 'warlike, ready to fight'.It is probably a reference towards the quarrelsome nature of the species towards conspecifics.

Illustration of a sexually mature female Betta pugnax. has been observed to feed on aquatic insects, terrestrial insects and spiders in Sungei Gombak, Malaysia (Wootton, 1992), though the ecology of the species in Singapore has not been fully-documented. Males have indistinct dark concerntric bars in the lance-shaped caudal fins. The dorsal fin commences a little behind the posterior half of the body; the rays gradually increase towards the fifth, the longest; the extent of the base is from 1/8 to 1/9 of the length of the body; the distance from the last ray to the caudal is 1/4 of the length of the body. Behind the velvety teeth of the upper jaw appears successively three semicircular membranous folds, of which the posterior is papillular on the margin, which thus appears as if studded with a second series of minute teeth.

Raffles Museum of Biodiversity Research, Department of Biological Sciences, National University of Singapore.Tan, Heok Hui. (Illustration: Low Bi Wei). When alarmed, these fish tend to scuttle into submerged leaf litter (Tan, 2011, pers. Failure to do so may result in overeager females immediately initiating a new breeding cycle, upon which starvation may set in.Figure 12. The species epithet is derived from Latin pugnax, which means 'warlike, ready to fight'. They are readily eating live baby brine shrimp and a variety of flake foods. Betta rubra is tentatively referred to the B. foerschi group. Peninsular Malaysia: Betta pugnax (Cantor, 1850), B. bellica Sauvage, 1884, B. imbellis Ladiges, 1975,B. Incubation takes around two weeks. Betta pugnax (Cantor, 1850). ), where it inhabits small, fast flowing hill-streams (Lim & Ng, 1990) and larger lowland streams (Lim, 2011, pers. It acts as the reference to all defining characteristics of that species.The lectotype for Betta pugnax is stored in the British Museum of Natural History (BMNH 1860.3.19:930; 60.6 mm SL; Pinang, collector Cantor). Adult females and juveniles with distinct chin-bar (oblique preorbital stripe), and two visible transverse bands (central and second central stripe) converging on a dark spot at the caudal peduncle (Figures 6,8). Betta pugnax est une espèce endémique de l' Asie. No lateral line appears, but on the series it would occupy if present, some of the anterior scales have each a central rounded depression, which, however, also appears on every single scales nearer the back. "The head is much depressed, and far broader than the body, which is gradually compressed towards the caudal fin. can be found across Peninsula Malaysia, in the states of Penang, Kedah, Terengganu, Pahang, Perak, Selangor and Johor, in Singapore, the Anambas Islands, the Riau Archipelago, Lingga Archipelago, and the Riau and Jambi provinces in Sumatra (Figure 3) (Tan & Ng, 2005). During this period, the male does not feed and becomes more retiring, staying hidden amongst dense aquatic vegetation (pers. The posterior opening of the nostrils is situated close to the orbit; the anterior is provided with a small fleshy tube. Fins of all type specimens are damaged (Tan & Tan, 1996). - Cantor, in his original descriptionThe general body shape and appearance of Betta pugnax (Figure 8) - body slender; caudal fin broadly lanceolate; dorsal fin originating above 13th lateral scale, pointed and posteriorly reaching the anterior third of caudal fin; anal fin originating below 7th lateral scale, posterior extremity pointed and elongated to the midlength of caudal fin.See here for detailed meristics and morphometrics. Raffles Museum of Biodiversity Research, Department of Biological Sciences, National University of Singapore. ), it is clear that the Betta pugnax complex group does not form a monophyletic clade. The specimen could either be released at the site by people, or it could have originated from downstream. ).Figure 9. Native distribution of Betta pugnax (red circles). Three series lower down, on the posterior half of the sides, commences sometimes a row of similar depressions, which then continue to the caudal fin. [8] [9] Species.

A typical anabantoid embrace and spawning rituals as illustrated by a pair of mouthbrooding, The hypothesized evolution of species can be inferred from phylogenetic studies. As males do not feed while brooding, they should be removed from the spawning tank upon release of fry, to allow for recuperation. There are two paralectotypes (BMNH 1860.3.19:317; 51.8 mm SL; BMNH 1860.3.19:318; 66.2 mm SL; Pinang; collector Cantor).The type locality for Betta pugnax is Penang, Malaysia.A type was not designated by Cantor when he described the species in 1850, which was based on an unspecified number of specimens. Maximum known size is 67.3 mm SL, and up to 10cm TL (Lim & Ng, 1990). Tan, H. H., and S. H. Tan. Notes on a collection of fresh-water fishes from Penang. obs.). The caudal is very broadly lanceolate; the two central rays are the longest, in some individuals 1/3 of the entire length of the fish, but frequently less. Betta pugnax are generally undemanding in captivity, readily accepting processed food and breeding if optimal conditions are met (pers. comm.).
