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).
通常生活在淡水, 但是在乾季的时候偶然地在间歇溪流的半咸淡水域中见到了。 也发现于被水淹没的田野,而且沼泽边缘沿着溪流与河川的路线。
