Linke (1992) recorded water temperature in collection localities at 26°C, falling to 22°C in the rainy season.In Singapore, Betta pugnax can be found in six undisclosed localities around the Nature Reserves (Tan, 2011, pers. Easily discernible diagnostic features are: i. preorbital stripe, ii. The eyes are prominent, occupying the second fourth, and bordering on the profile. 44(2):419-434. (From: Rüber et al., 2004; permission for use of figure obtained). 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. 246 Card. 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. Molecular phylogeny of the genus, derived using nuclear (RAG1) and mitochondrial (CytB, 12S rRNA, tRNA Val, 16S rRNA) nucleotide sequence data (4448 base pairs), with two Luciocephalinae taxa used as outgroups. for detailed meristics and morphometrics.

Betta pugnax a été décrit à partir d'une population qui peuple l'État de Penang en Malaisie. 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. The complex groups within the genus, should thus not be confused with the concept of, The study also hypothesized a model of brood care evolution within the genus. For best results remove brooding males or all other fish. Fins of all type specimens are damaged (Tan & Tan, 1996). their length but slightly exceeds 1/2 of the head. Betta pugnax (Penang betta) Pugnax – in Latin, it means ‘combative’. 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. If breeding is to be attempted, it is recommended that a pair be kept alone.

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. comm.). 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.

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. Head: Orbital diameter 27.9-38.5% HL; postorbital length 45.0-55.7% HL; interorbital width 32.4-53.0% HL. Other suitable tankmates include similar-sized, robust species with a peaceful demeanour, such as rasborines and some of the peaceable barb species . 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.

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 plesiomorphic condition (Rüber et al., 2004).
