Etymology: Microrasbora: Greek,mikros = small + Rasbora, a word used in India and Malay Peninsula; microphthalma: Derived from the Greek micro (small), ophthalm from opthalmos (eyes), in reference to its relative smaller eyes when compared to its congeners. More on authors: Jiang, Chen & Yang.

Morphology | Morphometrics
soft rays: 9 - 10;
Vertebrae: 30. Can be diagnosed from all its congeners by the following characters: pre-dorsal scales 15-16; predorsal length 60.68% of SL; preanal length 65-71% of SL; eye diameter 27-38% of HL and 70-93% of inter-orbital width; and dorsal fin origin posterior to pelvic fin insertion (Ref. 75599).
Occurs in small hill stream with sandy bottom and numerous cobblestones. Food items found in the intestines include zooplankton and phytoplankton (Ref. 75599).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00175 - 0.01195), b=3.15 (2.92 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
