Dorsal spines (total): 15 - 17; Dorsal soft rays (total): 9-11; Anal spines: 5-7; Anal soft rays: 7 - 9. This species differs from its congeners in having a lower jaw longer than upper and mouth pointing upwards; has the shortest dorsal scale cover and the least scaled dorsal and anal fins among (together with A. tembe); with four abdominal bars (present in more than 80% of individuals as compared to 50% or less in all other species (Ref. 74689).

Biology     Glossary (e.g. epibenthic)

An opportunistic diurnal feeder, eating detritus and plant material, preying on small aquatic animals, including small fish. Very resistant to low temperatures. (Ref. 59043). Common in creeks, rivers, swamps and lakes (Ref. 74689). This species is an easy open spawner that lays its eggs on a stone or piece of wood (Ref. 12251). Both parents care for the eggs and fry (Ref. 12251). Consumed locally. Reported to reach 25.0 cm SL (Ref. 59043).

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

This species is an easy open spawner that lays its eggs on a stone or piece of wood. Both parents care for the eggs and fry (Ref. 12251). In Europe where it has invaded native drainages, spawns when temperature rises above 28-30°C. Forms pairs during spawning and both sexes are territorial. Females deposits eggs on exposed hard surfaces such as stones or wood. Both parent guard larvae and juveniles for 1-3 weeks (Ref. 59043).
