- Water Conditions: Curupira Wolf Fish thrive in freshwater aquariums with a temperature range of 75°F to 82°F (24°C to 28°C). They prefer slightly acidic to neutral water with a pH level between 6.0 and 7.5. Adequate filtration and regular water changes are essential to maintain optimal water quality.

- Tank Size and Setup: Provide a spacious tank with a minimum capacity of 75 gallons (283 liters) to accommodate the size and activity level of Curupira Wolf Fish. They appreciate ample swimming space and hiding spots, so a well-decorated aquarium with rocks, driftwood, and caves is recommended.

- Tank Mates: Due to its predatory nature and potential aggressive behavior, the Curupira Wolf Fish is best kept alone or with large, robust fish species. Avoid keeping them with smaller, more delicate fish that may be seen as prey. It's crucial to research and select tank mates that can withstand the potential aggression of the Curupira Wolf Fish.

- Feeding Habit: Curupira Wolf Fish are carnivorous predators and have a voracious appetite. Offer them a varied diet of live or frozen foods such as fish, shrimp, worms, and small crustaceans. They may also accept high-quality pellets or carnivorous fish flakes. Feed them appropriately sized prey to ensure they can swallow it comfortably.

Provide a well-maintained aquarium with excellent filtration and perform regular water changes to ensure optimal water quality.

They may become more aggressive towards tank mates or even display aggression towards their own kind. Providing ample hiding spots and visual barriers can help reduce potential conflicts.

Little is known about their specific breeding requirements and behaviors, as most specimens available in the aquarium trade are wild-caught. Successful breeding usually occurs in large, species-specific setups with carefully controlled conditions.
