上頜些微地垂懸在下頜上方。 上嘴唇厚的。 頭部較寬的超過深地。 尾鰭圓的。
Amphidromous freshwater species (Ref. 92840). Often found in lower courses of rivers, ranging from freshwaters to brackish habitats (Ref. 57403, 79590), including brackish waters of intermittent streams during dry seasons (Ref. 5299), but may ascend far up rivers (Ref. 57403, 79590). Also found in flooded fields and marginal swamps along courses of streams and rivers (Ref. 5299). Not usually exceeding 139.8 mm SL, larger specimens may be misidentifications of A. bustamantei (Ref. 79590).
出現通常在淡水, 但是在乾季的時候偶然地在間歇溪流的半鹹淡水域中見到.。 也發現於被水淹沒的田野，而且沼澤邊緣沿著溪流與河川的路線。
