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).
雄魚的大帆狀背鰭是這一個魚的最特殊特性; 顏色能從綠色、灰色到墨黑色改變; 有斑點的型式也普遍.(參考文獻 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).
