Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 6.7, range 5 - 9.5 cm
Max length : 15.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5723); 10.0 cm TL (female); common length : 3.4 cm TL 雄鱼/尚未辨别雌雄; (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).
雄鱼的大帆状背鳍是这一个鱼的最特殊特性; 颜色能从绿色、灰色到墨黑色改变; 有斑点的造型也普遍.(参考文献 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).
