📖 Overview

Inhabits mainly larger cave streams at or near the water table where it has been observed in slow flowing pools at depths as shallow as 0.1 m to > 2 m deep. Reported to feed on copepods, isopods, and amphipods but larger individuals prey upon small crayfish. Spawning probably takes place during high water levels from February through April. Females incubate eggs in their branchial cavities until hatching and continue to care for fry until yolk reserves are depleted 4-5 months later. Likely attains sexual maturity in 3-4 years .
