背棘 (總數) : 2; 背的軟條 (總數) : 7; 臀棘: 1; 臀鰭軟條: 5.
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274); Found in small sluggish streams, floodplain lakes and large rivers generally in very soft water (Ref. 89711). Water quality measurements from Ushpa Caño showed that the water was very low in oxygen, but neutral (pH 7.0). Was observed to breathe air and when disturbed, would swim through the water column remaining neutrally buoyant. The species is not an obligate air-breather and does not routinely gulp air in well-oxygenated aquaria. Minimum temperature from Ref.13614.
發現於小的緩動性的溪流，洪泛區湖與大河了。 來自 Ushpa Cano 的水質測量顯示水是溶氧量很低, 但是中性 (酸鹼度 7.0). 被觀察呼吸空氣與當被驚擾時, 將會游泳保持中立有浮力的經過水團。 此魚種不是一個一定要呼吸空氣的魚類而且通常不會在溶氧度高的馴養環境中吞空氣。
