Though not so abundant, it is often caught in the quiet zones of cascades with G. harreri (Ref. 35237). Lives in mud and sand-bottomed canals. Maximum length 30 cm TL (Ref. 5723). Omnivorous, with a tendency towards herbivory, searches for food by digging into the substrate with its protractile mouth. Can emit sounds through its pharyngeal teeth though it is not known whether it is a form of communication or not. Spawning takes place on a flat stone or in a hole dug in the sand. Parents generally take the eggs into their mouths until hatching occurs three days later. At night or when faced with danger, the alevins seeks shelter in the mother's mouth. Parents take care of their siblings for several weeks (Ref. 35237).
雖然不是如此豐富, 它時常用 G. harreri 在小瀑布的安靜區域捕獲了.(參考文獻 35237) 生活在泥地與沙地底部的管。 最大的長度 30 公分TL.(參考文獻 5723) 雜食性, 具有一個趨向草食性, 藉由深入底部尋找食物用它的可伸出的嘴。 雖然它不為人所知它是否是一個溝通的形式，能經過它的咽齒發出聲音。 產卵在一塊平坦的石頭上或在一個洞中發生在砂中挖。 親魚通常帶卵進入他們的嘴直到孵化三天之後出現。 在晚上或當面對了危險, 剛孵化的小魚在母親的嘴中尋找庇護所。 親魚照顧他們的同源魚種好幾個星期。 (參考文獻 35237)
