| Husbandry Information | |
| Feeding | Feeds on small crustaceans, insects, snails and small fishes in the wild. Carnivorous but not a fussy eater in the aquarium. Will take most frozen/live/prepared foods, especially meaty types. |
| Furniture | Found in slow-flowing rivers and lakes with fringing vegetation, being more common in the latter. Hiding spaces in the form of PVC pipes and/or driftwood are necessary. |
| Compatibility | A peaceful, solitary species. Juveniles may form loose aggragations. Should not be kept with smaller fishes. |
| Breeding | Spawns when temperatures rise to between 20-24?Cduring spring and summer. Spawning is not stimulated by flooding. The number of eggs increases with size, ranging from about 2800 to 20600 eggs in females between 390 and 530 mm long. They build a circular to oval nest, generally around 0.6-2.0 m in diameter, from pebbles and gravel. During courtship, both male and femal circle and weave about the nest. The female then arches her body, agitates her pelvic fins and releases eggs about 30 cm above the nest. The eggs are spherical (about 3 mm in diameter), non-adhesive, and a light greenish yellow in color. The male fertilizes the eggs, which sink to the botom and settle into the gravel of the nest. One of the adults, usually the male, will remain at the nest until the eggshatch in about 7 days. The larvae are about 7 mm long when hatched, and barbels appear after 3 days. |
