Observed in limestone caves and sinkholes which are probably connected at depths between 2 and 30 meters; often in lightless chambers without current, few are found at the entrance of caves where they hide beneath rock ledges. No reaction to torchlight was shown and escape distance was only about 2 centimeters; mostly were seen motionless, with only a slight movement of the fins maintaining the fishes' position .
