生物學特性     字彙 (例如 epibenthic)

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).

棲息於小而水淺的池塘, 最多30 公分深與藉著滲流維持或泉水。 除非在 2007 年一月以22-24 °C 的水溫徹底攪拌,水是清澈的。 池塘主要地有繁茂的水下水生植物一或二個 Elodea Anacharis(Hydrocharitaceae) 的種。 存在的陸棲植物是開放的草地。 其他三個種在池塘被收集, 一個 Microrasbora 類似 M. rubescens; 一個 Yunnanilus 的小種; 而且一個以魚為食的 snakehead , Channa harbourtbutleri.(參考文獻 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).
營養階層 (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
