Down arrow Husbandry Information
Feeding A voracious predator. Juveniles can be fed live, frozen or pelleted foods; adults can be fed live fish, frogs or baby rats. May be taught to eat strips of raw meat.
Furniture A tankbuster that will outgrow almost any tank. Best kept in a pond. Provide large overhanging roots or pieces of driftwood as suitable hiding places.
Compatibility Given its voracious appetite, best kept alone. Any other tankmates will eventually end up as food.
Breeding Breeding does not occur until the water temperature reaches at least 20˚C, which is in mid-May to June to the south of its range and July to August in the north. The male excavates a redd (pit nest) in weedy gravel or sand-bottomed shallows into which the female deposits a clump of relatively large (3mm-diameter), yellow, sticky eggs. The number of eggs produced depends on the size of the female and is equivalent to 25000-30000 per kilogram of her weight.
After fertilizing the eggs, the male guards them until they hatch - usually three to four days later at temperatures of 20-21˚C. When newly hatched, larval catfish are about 7mm long and have only one barbel. They remain in the redd, guarded by the male, until their yolk sacs have been fully absorbed. They then disperse to feed on bottom-dwelling invertebrates and become piscivorous at the end of their first year (when they reach a size of 20-25 cm).
Breeding Reports There is no breeding report.
