Épines dorsales (Total): 3; Rayons mous dorsaux (Total): 7; Épines anales 3; Rayons mous anaux: 6. Mouth superior and transverse; 6 branched anal rays; barbels absent; distal margin of dorsal convex; large adults with sexually dimorphic coloration (Ref. 43281).

Biologie     Glossaire (ex. epibenthic)

Found in a wide variety of habitats, most abundantly in well vegetated small channels, ponds and small lakes (Ref. 59043). Adults occur in cool running water. Feed on small insects, fish and fish eggs (Ref. 30578), and plant material (Ref. 59043). Usually breed in habitats with still or very slow-flowing water (Ref. 59043). Females spawn 3-4 times in a season (Ref. 59043). Males clear the surface of the spawning site and guard the eggs until they hatch (Ref. 59043). Regarded as pest which competes with the fry of other species due to its high reproductive rate (Ref. 1739).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Nests under stones and the male cleans the cavity with its pearl organs. Eggs adhere to the ceiling of the cavity. The male leaves the nest before the eggs hatch. Females spawn 3-4 times during a season (Ref. 59043).
