生物學特性     字彙 (例如 epibenthic)

Calm and timid. Typical species of wooded rivers where the current is slow and the bottom is covered with dead leaves. Sexual differentiation is possible at the age of two months (Ref. 27188). Not a seasonal killifish (Ref. 27139). Difficult to breed in the aquarium. Eggs measure 1.6 mm in diameter (Ref. 35237).

平靜與膽小的。 水流慢的樹木繁茂河的典型種與底部被覆蓋著枯葉的地方。 性的區別在二個月大的時候是可能的。 (參考文獻 27188) 不是一個季節性的鱂科魚類.(參考文獻 27139) 困難的在水族館繁殖。 卵測量 1.6 mm 直徑。 (參考文獻 35237)

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=0.00912 (0.00512 - 0.01625), b=3.14 (2.98 - 3.30), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
營養階層 (Ref. 69278):  3.3   ±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).
