Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 6.7, range 5 - 9.5 cm
Max length : 15.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5723); 10.0 cm TL (female); common length : 3.4 cm TL 雄魚/尚未辨別雌雄; (Ref. 12193)
The large sail-like dorsal fin of the male is the most distinctive characteristic of this fish; coloration can vary from green, gray to jet black; speckled forms also common (Ref. 44091).
Found in still or gently flowing warm water of small creeks and drains (Ref. 44894). Occurs in ponds, lakes, sloughs, and quiet, often vegetated, backwaters and pools of streams (Ref. 5723) and also in coastal waters (Ref. 7251). Abundant in tidal ditches and brackish canals. Feeds mainly on algae (Refs. 7251; 44091), also consumes animal material: rotifers, small crustaceans (such as copepods and ostracods) and aquatic insects (Ref. 79012).
After 28 days gestation, this species produces 10 to 100 young.
