This species has no status in Eschmeyer (CofF ver. Jul. 2010: Ref. 84883), however the species is well known and documented in Chen & Chang (2005: Ref. 084731) (S. Kullander, pers. comm., July 2010).

Vertebrae: 8. This species is characterized by the following: compressed body, incomplete ventral keel, extending from anus toward the ventral fin base; complete lateral line, extending to caudal fin base; terminal mouth, extending slightly beyond vertical of anterior margin of orbit; origin of dorsal fin closer to caudal fin base than tip of snout; rather large eyes; wide interorbital area; moderately large scales; greyish on dorsal side, pale white laterally; scale pocket darker than the background; body sometimes scattered with few grayish brown spots in lateral; all fins translucent and slightly yellowish; body length up to 12 cm, usually seen as 4-8 cm (Ref. 84731).
A medium sized fish that prefers shallow waters of sluggish streams or ponds with inflow water. It usually hides between dense aquatic vegetation to avoid predation. Feeds mainly on small aquatic invertebrates, any sizable floating organic fragments and surface-drifting terrestrial insects. A common food fish. Threatened by degradation of habitat (construction of hydroelectric power caused drastic diel fluctuation of water level (release and refilling of water) thus preventing growth of aquatic vegetation). It can now be found only in several streams near its type locality and is diminishing progressively, unless measures are undertaken to rescue remaining populations and to restore their habitats (Ref. 84731)

50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00301 - 0.01323), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 2.7 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Moderate vulnerability (37 of 100) .
