Adults inhabit subterranean waters of quite small cave streams. Preferred habitat in these caves is chert rubble though individuals are also found in areas of silt-sand substrates. Stomachs examined contained copepods which constituted about 70-90% by volume with the balance being primarily small salamanders, crayfish, isopods, amphipods and young of their own species (Ref. 34868). Eggs are carried in gill chambers of females (Ref. 205). Threatened by overfishing (Ref. 10172).
栖息于相当小洞穴溪流的地下水域。 虽然它也被发现于淤泥-沙子底部的区域，在这些洞穴的它的优先栖息地是黑硅石碎石。 腹部检查后发现有了构成大约体积的 70-90% 的桡脚类的动物其余主要是小的蝾螈，小龙虾，等足目动物，片脚类动物与同种的幼鱼.(参考文献 34868) 受到威胁的由于捕捞过度。 (参考文献 10172)
