Down Husbandry Information
Feeding Will eat anything and everything. In nature the diet consists of fish, shrimp, and crab. Like all large predatory catfishes, it should only be fed every two to four days once it reaches 12 inches in length. User data.
Furniture Normally found over rocky substrates at irregular depths.
Large driftwood and rocks should be used to make a cave for the fish to hide in. All filters, heaters, etc should be behind a protective barrier as this fish can, and will, bite through a heater. This is a fish for someone with a very large tank that wants a true ''pet'' fish.
Compatibility Not compatible with other fishes due to its nasty disposition. Many claim that H. wyckioides is the most aggressive freshwater fish in the world. Given this fish's ability to bite, it is not even safe with tank mates too large to swallow since it will simply take bites out them.
Breeding Unknown. Roberts (1993) claims that H. wyckioides does not migrate to spawn, but reproduces locally. It enters the flooded forest in the wet season (July-October).
Breeding Reports There is no breeding report.
