Description
The Marbled Eel Catfish is a nocturnal, eel-like fish native to South America, characterized by its mottled brown coloration. It is a predatory species that thrives in dimly lit aquariums with ample hiding places, emerging at night to hunt. While generally peaceful with larger tankmates, it will prey on very small fish.
