成熟度: Lm ? range ? - ? cm
Max length : 4.7 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5723); common length : 3.5 cm TL 雄鱼/尚未辨别雌雄; (Ref. 12193); 最大年龄: 3.00 年 (Ref. 12193)
Body shape (shape guide): fusiform / normal; Cross section: oval.
Adults occur in swamps, heavily vegetated sloughs and small sluggish streams, usually over mud (Ref. 10294, 58020). They feed on microcrustacea together with midge larvae, larger crustacea (isopods and amphipods), mayfly nymphs, and small snails and clams (Ref. 10294). Oviparous, eggs are deposited in aquatic vegetation, preferably on strands of Ceratophyllum sp. when available (Ref. 58020).
出现于沼泽,长满植物的泥坑与小的缓动性的溪流, 通常在泥上面。
