Oddly, this small, eyeless juvenile seems to be attracted to light sources. In a laboratory environment, it can be trained to swim in a pattern based on lights turning on and off. It feeds only once every few days but can consume nearly half its weight in food, though it becomes lethargic for several hours afterward. When kept with other juveniles of its species, it shows little interest in interacting, keeping to its own space and moving its tail and fins in short, menacing motions if another approaches too close.
