Cave-restricted species (Ref. 12041). Collected in a pool of moving water about 1 km from a cave entrance (Ref. 39226). Mostly found stationary on the muddy bottom at depths from 20 cm to 1 m (Ref. 42927). Tends to occur in slow moving water during the dry season, but some individuals were observed climbing rapids (Ref. 42927). Small groups of individuals were frequently found in the pools while isolated individuals were common in rapids (Ref. 42927). Weakly or not at all cryptobiotic, not remaining under rocks for more than 5 min during the day (Ref. 42927). Feeds on insects and roundworms (Ref. 42927). Shows behavioral responses to light, including avoidance and perhaps a residual diurnal rhythmicity (Ref. 42927). |
