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).
棲息於河。 (參考文獻 12251) 豐富的, 出現於在安靜的﹐水淺的與晴朗的水域中, 小瀑布的區域以及 伊氏克羅比麗魚〔Krobia itanyi〕 ， Corydoras guianensis ， 紋背溪脂鯉〔Characidium fasciadorsale〕 與 Cyphocharax spilurus中。 在 Oelemari 河，蘇利南中與 G. oelemariensis 重疊分佈了。 (參考文獻 26372) 吃小型無脊椎動物。 繁殖可能出現 3 到 4 倍每年。 產卵發生於岩石的彎曲的水道所以守衛者比較容易母魚通常那是比雄性更小。 雄性防護巢。 根據食物的親代養育供應，而且保護持續達 1 到 3個月.(參考文獻 35237)
