Maturity: Lm ? range ? - ? cm
Max length : 7.6 cm TL mâle / non sexé; (Ref. 5951); common length : 3.5 cm TL mâle / non sexé; (Ref. 12193); âge max. reporté: 1.00 années (Ref. 12193)
Adults occur near shore in beds of vegetation, often around floating vegetation a short distance from shore. Rarely enter fresh water (Ref. 7251). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).
