Aquarium Setup

To house Orinoco Peacock Bass successfully, an extremely large tank is required due to their territorial and moderately aggressive nature. The tank should be set up with ample swimming space and furnished sparsely with large pieces of bogwood and robust plants. Adequate filtration, preferably external or sump filtration, is necessary to maintain water quality. The recommended water conditions include a pH range of 5.5-6.5, hardness of 5-15°dH, and a temperature between 27-29°C (see table).

Behaviour

Orinoco Peacock Bass are known to be territorial and moderately aggressive, making it essential to house them with other large species like arowana, stingrays, large cats, or other large cichlids. They have a tendency to prey on tankmates small enough to be considered food, requiring careful consideration when choosing tank companions.
