Inhabits rivers (Ref. 12251). Abundant, occurs in the zones of cascades along with Krobia itanyi, Corydoras guianensis, Characidium fasciadorsale and Cyphocharax spilurus, in quiet, shallow and sunny waters. Sympatric with G. oelemariensis in the Oelemari River, Suriname (Ref. 26372). Feeds on small invertebrates. Breeding may occur 3 to 4 times per year. Spawning takes place in anfractuosities of rocks so that guarding is easier for females which are generally smaller than males. Males defend the nest. Parental care in terms of food supply and protection lasts for 1 to 3 months (Ref. 35237).
栖息于河。 (参考文献 12251) 丰富的, 出现于在安静的，水浅的与晴朗的水域中, 小瀑布的区域以及 伊氏克罗比丽鱼［Krobia itanyi］ ， Corydoras guianensis ， 纹背溪脂鲤［Characidium fasciadorsale］ 与 Cyphocharax spilurus中。 在 Oelemari 河，苏里南中与 G. oelemariensis 重叠分布了。 (参考文献 26372) 吃小型无脊椎动物。 繁殖可能出现 3 到 4 倍每年。 产卵发生于岩石的弯曲的水道所以门卫者比较容易母鱼通常那是比雄性更小。 雄性防护巢。 根据食物的亲代养育供应，而且保护持续达 1 到 3个月.(参考文献 35237)
