FeedingYoungsters are more carnivorous than adults. Bloodworm and catfish tablets are best at first, moving onto shrimp and spinach cubes as the fish get larger. Ultimately any primarily vegetable based floating pellet foods.
FurnitureAs little as possible, this fish needs space. Floating plants will reduce this fishes skittishness.
CompatibilityPeaceful; can be kept with smaller fish, although this fishes extreme nervousness will affect what fish you can keep with it.
Suggested TankmatesLarge active fish, the bigger barbs, Labeo ''sharks'', Loricariids, Pacu.
BreedingUnknown and probably impossible in the confines of a home aquarium. Is commercially bred for the aquarium trade in large ponds.
