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).
虽然不是如此丰富, 它时常用 G. harreri 在小瀑布的安静区域捕获了.(参考文献 35237) 生活在泥地与沙地底部的管。 最大的长度 30 公分TL.(参考文献 5723) 杂食性, 具有一个趋向草食性, 藉由深入底部寻找食物用它的可伸出的嘴。 虽然它不为人所知它是否是一个沟通的形式，能经过它的咽齿发出声音。 产卵在一块平坦的石头上或在一个洞中发生在砂中挖。 亲鱼通常带卵进入他们的嘴直到孵化三天之后出现。 在晚上或当面对了危险, 刚孵化的小鱼在母亲的嘴中寻找庇护所。 亲鱼照顾他们的同源鱼种好几个星期。 (参考文献 35237)
