Inhabits warm water artesian springs and their outlet streams (Ref. 2906, 44894). Tolerates temperatures ranging from 20°-39°C, but has been recorded briefly entering water of 41.8°C to feed. A diurnally-active species which has one of the highest recorded voluntary temperature tolerances of any fish species in the world (Ref. 44894). Feeds on gastropods, aquatic plants (Ref. 2906), green filamentous algae, detritus and small invertebrates which are taken from the bottom (Ref. 44894). Dimorphic: bigger females with concave head and flat belly, long cylindrical sac-like ovary on left side of fish while the yellow-white testis lies on the right side. Appears to suffer thermal stress above 38°C but can tolerate low oxygen levels (Ref. 7276).
栖息于温暖的水喷水井的泉水与他们的出口溪流。 (参考文献 2906,44894) 容忍温度范围从 20个 °-39 °C, 但是已经简短地被记录进入 41.8 °C 的水觅食。 一日行性-有最高的之一的活跃的种记录了任何鱼种的自动容忍温度世界上.(参考文献 44894) 吃腹足动物，水生植物 (参考文献 2906) ，绿色的菌丝藻, 碎屑，而且小型无脊椎动物那是取自底部。 (参考文献 44894) 双型性的: 较大的雌性有凹的头部与平坦的腹面, 长的圆筒形的囊状卵巢在鱼左边上然而黄色-白色的精巢躺在右邊上。 似乎耐熱超過 38 °C 但是能容忍低溶氧量.(參考文獻 7276)
