Short description Identification keys | Morphology | Morphometrics

Anal spines: 3; Vertebrae: 30 - 32.

Inhabits small and shallow ponds, at most 30 cm deep and maintained by seepage or springs. The water is clear unless roiled with water temperatures of 22-24°C in January 2007. The ponds have luxuriant submerged aquatic vegetation mainly one or two species of Elodea or Anacharis (Hydrocharitaceae). Present terrestrial vegetation is open grassland. Three other species were collected in the ponds, a Microrasbora similar to M. rubescens; a small species of Yunnanilus; and a piscivorous snakehead, Channa harbourtbutleri (Ref. 57973).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00210 - 0.01198), b=3.15 (2.93 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.4 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.).

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