Relevant Information:

Habitat: Inhabits riverbeds, deep wells and lakes. Young or sub-adults form large schools. Prefers to lay over rock and tree trunks during the day, being more active at sunrise, sunset and night. Aquarium Care: Not to be trusted with small fishes as they will be chased down during the night forays of this catfish. Would need a large aquarium due to its eventual size with a clear area to the front of the tank and hiding places for it during the daylight hours such as large clay land pipes and clay pots. Diet: Small feeder fishes, lean beef, aquatic insect larvae, tablet and frozen foods. Etymology: The specific name marmoratus: Marbled; mottled.
