Occurs in principal river beds, in upstream parts of rivers, downstream rapids, in backwater zones or on stony bottoms of pools with dead tree trunks. Active at dusk. Piscivorous. Emits loud grumblings (Ref. 35381). Secretes toxic mucus and the wounds caused by its pectoral spines are very painful. The female can preserve spermatozoids by coating them with original maternal secretions and inserting them in the epithelium of its genital tract (Ref. 27188). The presence of sperm in the mucus of the female's genital tract is indicative of internal fertilization (Ref. 35381).
在河的向上游部份中,出现于主要的河床, 顺流而下急流, 在回流水区域中或在水池的多石底部上 ，有死树干的地方。 活跃的在薄暮。 以鱼为食的。 发出大声的咕哝声。 (参考文献 35381) 分泌有毒的黏液，而且由它的胸棘引起的创伤非常令人痛苦。 母鱼能用最初的母亲分泌保护涂料的精虫他们而且插入他们在生殖道的上皮中.(参考文献 27188) 那有在母鱼的生殖道的黏液中的精液指出体内受精.(参考文献 35381)
