Down Husbandry Information
Feeding Will accept pellet and flake food(when young) in captivity. In the wild both young and adults feed on fishes and crustaceans. Examination of two young specimens (60 and 80 cm) had only small fishes in their stomachs. The larger fish had eaten three Pangasius macronema of 15 - 20 cm each, one Belodontichthys (a predatory silurid catfish) and one small cyprinid. Larger individuals will take the carcasses of fowl or dogs (commonly used for bait). User data.
Furniture Needs vast amount of open space for swimming room and some plants to help reduce the nervous nature of the fish.
Compatibility Not recommended for home aquaria.
Suggested Tankmates Not recommended for home aquaria.
Breeding Unsurprisingly, unreported in captivity.
