簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 5 - 7; 背的軟條 (總數) : 9 - 12; 臀棘: 1; 臀鰭軟條: 18 - 21. Scales: horizontal rows 10-13; vertical rows 31-36; predorsal 14-22; cheek 9-13. Greatest body depth (>5 cm SL), females 30.5-36.2 and males 32.9-41% of SL (Ref. 44894).
Habitat where found is highly variable, including rivers, creeks, swamps, marshy lagoons, lakes, and reservoirs. Usually forms aggregations at or near the surface of deeper pools in stream habitats, especially where there is aquatic vegetation or log debris (Ref. 44894).
