A cave inhabitant. Juveniles inhabit close to the cave entrance, subadults and adults occur deeper, at least 100 m from the entrance. Juveniles occupy the whole water column, from surface to bottom. Subadults and adults stay close to the bottom and midwater, usually in slow current. The stomach contents of 18 cm specimen include organic detritus, possibly bat guano, and calcareous ooze of the limestone weathering.
