Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Deposits eggs on underside of objects above the water surface. Male in water splashes the clutch periodically (Ref. 7471). In the aquarium, male and female swim vertically to the surface, flick their tails and leap up to a leaf. Female lays from 5 to 8 eggs on the leaf and male fertilizes them immediately. This procedure is repeated several times until some hundreds of eggs have been laid. Male then keeps the eggs damp by flicking his tail to spray them with water. As eggs hatch, fry fall into the water (Ref. 7020).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00385 - 0.01244), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.40 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Females can lay hundreds of eggs (Ref. 7020)).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
