Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 17; Anal spines: 0; Anal soft rays: 15. Diagnosis: Nothobranchius robustus is the only species of the genus with uniform brown-red fin colouration on both dorsal and anal fins (Ref. 123150).

Found in marginal, ephemeral, zones of permanent water bodies such as flowing creeks in papyrus swamps, small streams and dead river branches (Ref. 26661, 59344). Usually inhabits the more shallow and quiet parts between bordering vegetation; occasionally in temporary pools (Ref. 26661). Occurs in low water temperatures (21.8°C on average) (Ref. 97291). Incubation period of eggs in captivity is 4-8 weeks and young reach maturity at about 8 weeks (Ref. 59344). Bottom spawner, 4 months incubation (Ref. 27139).

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=0.01122 (0.00472 - 0.02669), b=2.94 (2.74 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
