Inhabit rocky pools of headwaters, creeks and small rivers (Ref. 5723, 10294). Adults feed on midge larvae, mayfly and stonefly nymphs, and crustaceans (Ref. 10294). Eggs are found clustered on underside of stone and guarded by males (Ref. 7043).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Weerstandsvermogen (Ref.
