Betta Breviobesa

📖 Overview

Betta Breviobesa (Betta breviobesa), first described by Tan & Kottelat, 1998 is a small fish in the family Osphronemidae (order Anabantiformes). Adults typically reach 6.50 cm in maximum length. It inhabits freshwater systems including rivers, streams, and lakes. It occurs in Tropical waters. It is broadly omnivorous, taking invertebrates, plant matter, and detritus. On the IUCN Red List, it is classified as Vulnerable.The species is kept in the aquarium hobby. Care requirements and behaviour align broadly with other Osphronemidae kept in the hobby.

🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 1; Dorsal soft rays (total): 8; Anal spines: 2; Anal soft rays: 24. Differs from B. enisae by: the absence of caudal transverse bars versus presence; more anal rays (25-27, mode 27, versus 23-26, mode 24-25); more subdorsal scales (5 1/2-7, mode 7, versus 5); more lateral scales (28-30, mode 30, versus 26-28, mode 27); smaller predorsal length (62.1-67% SL, versus 67.3-70.3); larger body depth at dorsal-fin origin (28.7-32.8% SL, versus 26.2-28.9); slightly longer pelvic fin (33.9-55.4% SL, versus 33.8-46.7); longer dorsal-fin base (11.4-14.9% SL, versus 8.7-12.1); smaller total length (12.8-15.1% SL, versus 14.3-15.5); smaller orbit diameter (48-69% of postorbital length, versus 57-68); smaller interorbital width (64-74% of postorbital length, versus 70-76) . Can be further differentiated from its congeners by: the absence of chin-bar (versus presence in B. pugnax, B. prima and B. pulchra); presence of dark distal borders on anal and caudal fins (versus absence in B. pugnax, B. fusca, B. schalleri, B. prima and B. pulchra; absence of caudal transverse bars (versus presence in B. pugnax and B. pulchra; more anal rays than B. fusca (25-27, versus 24-25); fewer lateral scales than B. schalleri (28-30, versus 31); more predorsal scales than B. schalleri (19-21, mode 21, versus 17-19, mode 19); more postdorsal scales than B. prima (11-12, versus 9-10); greater head length than B. fusca (51.3-54.3% predorsal length, versus 47.2-49.4); smaller predorsal length than B. fusca and B. prima (62.1-67% SL, versus 68.1-70.2); smaller postdorsal length than B. prima (21.9-23.4% SL, versus 24.1-26.3); smaller preanal length than B. prima (48-51.5% SL, versus 50.6-54.8); greater body depth than B. schalleri (28.7-32.8% SL, versus 26.7-27.6); longer pelvic fins than B pugnax (filamentous tip reaching 9-18th anal ray, versus 4-10th; 33.9-55.4% SL, versus 26.6-43.8); longer anal-fin base than B. fusca and B. schalleri (51.1-54.5% SL, versus 47.8-52); smaller orbit diameter than B. pugnax and B. pulchra (24.2-28.5% HL, versus 27.9-38.5); smaller interorbital width than B. pugnax and B. pulchra (29.6-36.1% HL, versus 32.4-53) .: fusiform / normal.
