Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 14-15; Raggi anali molli: 8; Vertebre: 39 - 41. Distinguished from other species of Hemirhamphodon in having the following characters: discernable markings on body and fins absent, except dorsal part of caudal fin base with sparse black pigments on both male and female; and submargin of dorsal fin suffused with black pigments; small adult size, up to 41 mm SL; adult sizes for male and female similar (as with H. tengah), other congeners with males up to 50% larger than females; males with an enlarged posterior projection on the fourth anal-fin ray, with third, fourth, sixth and eighth anal-fin rays branched; females with third, fourth and eighth anal-fin rays branched; pelvic-fin origin anterior to dorsal-fin origin; and dorsal fin with 14 to 15 rays (Ref. 94086).

Inhabits streams with submerged bank vegetation and clear water of pH 7.0 flowing over rocky, sand and silt substratum. Tends to form school in small groups of about 3 to 5 individuals at the surface, preferring quiet pools and dwelling near or under overhanging bank vegetation. Syntopic with Osteochilus vittatus, Rasbora elegans, Systomus binotatus (Cyprinidae), Betta patoti, Trichopodus trichopterus (Osphronemidae), and Channa lucius (Channidae).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
