生物学     用語集 (例 epibenthic)

Facultative air-breathing (Ref. 126274); Inhabits slow moving streams, rivulets and lakes with plenty of vegetation (Ref. 41236). An air-breathing species (Ref. 118402). Aquarium keeping: minimum aquarium size 60 cm (Ref. 51539).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

Male guards the floating bubble-nest where the eggs are laid, about 600 in number. Hatching takes place in 12 to 24 hours while the male parent continues to protect the nest. In about three days, the developing larvae become free-swimming and leave the nest. In an aquarium setting, it is about this same period that the male should be removed from the tank to lessen the probability of him eating the young (Ref. 1672).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.01096 - 0.01906), b=2.98 (2.90 - 3.06), in cm total length, based on LWR estimates for this species (Ref. 93245).
栄養段階 (Ref. 69278):  2.9   ±0.1 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  手段, １．４年～４．４年の倍増期間の最小個体群 (Fec=600 eggs (Ref. 1672)).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
