Wolf Fish
Hoplias malabaricus
Water Parameters
About
The Wolf Fish is one of the most efficient freshwater predators in South America. With a cylindrical body, flattened head, and powerful jaws full of sharp teeth, it is an ambush machine. Although not colorful, it fascinates predator fish enthusiasts with its hunting behavior and interactive personality.
Behavior & Temperament
Voracious, solitary predator that ambushes prey. Extremely aggressive and territorial. Kept only as a single specimen or in tanks with very large predators.
Feeding
Strict carnivore. Feeds on fish, shrimp and insects. In aquariums, accepts live fish, fish fillets, shrimp and can be trained to accept dead foods.
Breeding
Oviparous. Builds a nest, and both parents aggressively guard the eggs and fry. Breeding is possible in very large aquariums.
Care Notes
Large aquarium with plenty of hiding spots (driftwood, caves). VERY secure lid because it can jump. Handle with care (may bite and cause serious injuries). Feed with appropriate prey, avoid sick fish.
Compatibility
NOT compatible with any fish that fits in its mouth (most of them). Only with very large, robust fish. Best kept alone. Voracious predator that eats anything it can swallow.
