Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 10 - 12.

Adults inhabit lower reaches of rivers (also found further upstream) in flowing or still water (Ref. 44894) among aquatic vegetation or branches of submerged trees. Juveniles often occur in swiftly flowing water or brackish estuaries. Tolerant of salinity levels equal to sea water, temperatures up to 35°C and pH 5.0-9.1 (Ref. 44894). Feed on micro-crustaceans, mosquito larvae and algae. Spawning occurs during the warmer months, when males establish breeding territories and display their dazzling colours to attract a mate. The eggs adhere to rocks, sand or weeds and are guarded and fanned by the male until hatching, which occurs in 10-14 hours (Ref. 44894). Smallest vertebrate eggs with max 0.32 mm length. Hatching larvae are about 1mm long.

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

The male sets up a territory on the bottom and entices the female to deposit up to 3,000 eggs on rocks, logs or plants. Male guards the nest throughout the incubation period of 10-14 hours (Ref. 5259).

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=0.01023 (0.00391 - 0.02676), b=3.02 (2.79 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.35 se; based on food items.

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).

Price category (Ref. 80766): Unknown.
