Maturity: Lm ? range ? - ? cm
Max length : 17.0 cm TL mâle / non sexé; (Ref. 5723); common length : 6.1 cm TL mâle / non sexé; (Ref. 12193)
Prefers lower and middle sections of rivers in slow moving waters (Ref. 7335). Lives in mud-bottomed and sand-bottomed canals and rocky ponds (Ref. 5723). Stays close to the shoreline vegetation for protection (Ref. 44091). Omnivorous, but feeds mainly on algae (Ref. 6466). Used in behavioral studies (Ref. 4537). Aquarium keeping: minimum aquarium size 100 cm (Ref. 51539).
Life cycle and mating behavior
Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larves
Deposits eggs on open substrate such as stones (Ref. 6466), a piece of submerged wood, or a shallow depression excavated in the substrate; from 100 to 500 eggs are deposited and guarded by both parents; newly hatched young are transferred to shallow pits and the parents continue guarding them (Ref. 44091).
