Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Africa: lower Zambezi and lower Pungwe River systems in Mozambique; also likely to occur in floodplains of other rivers between Zambezi and Pungwe Rivers (Ref. 85866).

Biology     Glossary (e.g. epibenthic)

Occurs in temporary pools and swamps or water-filled depressions; water depth variable an descreases as dry season progresses; littoral vegetation consists of grasses; swamps may be used to cultivate rice (Ref. 85866). Bottom spawner, 4-6 months incubation. Is very difficult to maintain in aquarium (Ref. 27139).

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

Annual fish. Matures after 12 weeks. This updates previous information from Ref. 1672.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00448 - 0.02560), b=2.92 (2.71 - 3.13), based on LWR estimates for this Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
