Facultative air-breathing in the genus (Ref. 126274); Occur in slow-running, tea-colored streams usually in sandy areas. Also found in swamps, small ponds and roadside ditches. Also lives in the vegetated shallows of some freshwater lakes. Water is typically acidic (pH 4.5-6.5) and darkly tannin-stained. An inhabitant of temporary waters, capable of aestivating in damp bottom sediments over summer. Spawning habits similar to G. munda. Most individuals perish after their first spawning (Ref. 44894). Feed on small insects, larvae of aquatic insects and micro-crustaceans. Breeding is associated with winter rains. Males take on a bright color pattern at the start of the breeding season (Ref. 33842).
出现在流动缓慢又茶色的溪流通常在沙地。 也发现于沼泽，小的池塘与路傍沟渠。 也生活在长满植物浅滩中一些淡水湖泊。 水典型酸性的 (酸碱度 4.5-6.5) 与暗单宁酸-沾染。 一个暂时水域的栖居动物, 能够在夏天以来的在潮湿的底部沉淀物中的夏眠。 产卵习惯类似 G. munda 。 大多数的个体在他们的第一个产卵之后死亡。 (参考文献 44894) 捕食小的昆虫，水生昆虫幼生与细小的甲壳动物。 繁殖被伴随着冬天雨。 雄性承担一个明亮的彩色斑纹在那繁殖季节的初始。 夏眠是有可能的當許多水體在那一個這種被發現是短暫存在的.(參考文獻 33842)

Bayesian length-weight: a=0.00490 (0.00205 - 0.01170), b=3.12 (2.91 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Generation time: 0.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
