Facultative air-breathing in the genus (Ref. 126274); Lives in the lower reaches of rivers within the limit of the brackish water and the first rapids (Ref. 35381). Very abundant in estuaries; prefers dead tree trunks and the vast zones of flooded vegetation (Ref. 27188). Also occurs on the muddy bottoms of the banks occupied by Montrichardia arborescens, moving together Loricaria cataphracta and Pimelodus blochii according to the tide. May use its stomach as an accessory breathing organ. Feeds mainly on unicellular algae and then on protozoa, rotifers, nematodes and arthropods as accessory food items (Ref. 35381).
生活在半淡咸水的范围里面的河与水流最急的地方下面范围。 (参考文献 35381) 非常丰富的在河口; 偏爱死的树干与茂盛的植物的大量区域。 (参考文献 27188) 也生存于被 Montrichardia arborescens 占领的浅堆的泥底部, 一起移动 Loricaria cataphracta 与 布氏油鲶［Pimelodus blochii］ 根据潮水。 作为一个附属的呼吸器官会用它的腹部。 主要吃单细胞的藻类然后在原虫，轮虫，线虫类与节肢动物上如附属的食物组成.(参考文献 35381)
