Long-lived and gregarious species. Occurs over sandy substrate (Ref. 27188). Frequently found in the rapids, thereby suggesting the need for a lot of space and well-aerated water for maintenance in the aquarium. Oviparous (Ref. 205). Can be caught using lines with crushed meat as bait but is also known to feed on plants. Is capable of powerful leaps out of the water (Ref. 12225).
長命而群居的種。 生活在砂質底部之上。 (參考文獻 27188) 時常發現於急流了,藉此在水族館為維護建議對許多空間與曝氣良好的水域需要。 卵生的.(參考文獻 205) 能用碎肉當餌被使用線捕捉但是也被知道覓食植物。 能夠有力的從水中跳出來.(參考文獻 12225)
