Etymology: Rasbora: Rasbora, an Indian word for a fish, also used in Malay peninsula.
Eponymy: Dr Maurice Kottelat (d: 1957) is a Swiss ichthyologist who specializes in Eurasian freshwater fishes and has described more than 440 fish species previously unknown to science. [...] (Ref. 128868), visit book page.

Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 6.0 cm SL male/unsexed; (Ref. 30857)
Dorsal soft rays (total): 10; Anal soft rays: 8. Complete lateral line; 7 scales between lateral lines over the dorsum, on caudal peduncle; dorsal-hypural distance, when carried forward, falling on nostril; origin of dorsal fin behind posterior margin of pelvic fin base; color pattern consisting of a dark lateral stripe from opercle to caudal base, ending in a precaudal spot. This kind of color pattern is shared with R. sumatrana only, from which R. hobelmani differs by the lateral stripe being wider on the body between opercle and vertical of dorsal fin than on the caudal peduncle (versus of regular width) and somewhat diffuse (versus black), a paraxial stripe being distinct (versus under lateral stripe).
Found from midwater to surface in pools of small upland streams (Ref. 12693). Feed on insects (Ref. 33813). Spawning sites are found in rivers and ponds (Ref. 33813). Mature adults probably breed during the rainy season. Not seen in markets. May possibly seen be used in the aquarium trade (Ref. 12693).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00286 - 0.01676), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±0.40 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
