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,出現於主要的河床, 順流而下急流, 在迴流水區域中或在水池的多石底部上 ，有死樹幹的地方。 活躍的在薄暮。 以魚為食的。 發出大聲的咕噥聲。 (參考文獻 35381) 分泌有毒的黏液，而且由它的胸棘引起的創傷非常令人痛苦。 母魚能用最初的母親分泌保護塗料的精蟲他們而且插入他們在生殖道的上皮中.(參考文獻 27188) 那有在母魚的生殖道的黏液中的精液指出體內受精.(參考文獻 35381)
