Pimelodus Pictus

Datasheet

Behaviour

The Pictus Catfish is generally peaceful, yet as a predatory species, caution is advised when selecting tankmates, as it may target smaller fish. It is best suited for spacious tanks with inhabitants that are too large to be consumed. With its high activity levels and long barbels, it may bother slower-moving tankmates, particularly at night or during feeding times. Ideal companions include robust and active species such as Rainbowfish, medium to large-sized characins, cyprinids, and sturdy catfish like Loricariids or Doradids. While a single specimen can survive alone, Pictus Cats are naturally shoaling and thrive in groups of six or more, exhibiting more outgoing behavior in a group setting.

Feeding and Diet

The Pictus Catfish is a versatile eater, preying on aquatic invertebrates in the wild but showing a voracious appetite in the aquarium. It readily accepts a variety of foods, including live or frozen bloodworms, Tubifex, small earthworms, and dried sinking foods. Care must be taken not to overfeed, as this species tends to overeat to the point of a distended stomach. Feeding every few days is sufficient for adults. In a group, their feeding response is lively, reaching a frenzied state quickly. Some acclimation may be needed, with supplementary feeding at night initially until they adjust to their environment.

Reproduction & Dimorphism

Reproduction of the Pictus Catfish has not been documented in captivity. Sexual dimorphism is unconfirmed, but adult females are likely to have a more robust build than males.

Habitat and Distribution

Native to the Rio Orinoco and Amazon basins in Colombia, Venezuela, Peru, and Brazil, the Pictus Catfish is typically found in shallow, flowing waters with sandy or muddy substrates, including major rivers and tributaries.

Aquarium Setup

For optimal well-being, the Pictus Catfish thrives in dimly lit tanks with ample swimming space and hiding spots. A fine sandy substrate mimicking their natural habitat is preferred. Including driftwood, roots, branches, and smooth stones can create a riverine environment. Hardy plants like Anubias or Java fern can be added, attached to decor to maximize floor space. Strong filtration with good water flow and weekly partial water changes are crucial for maintaining optimal water conditions due to the species' sensitivity.

Ensure water hardness between 1-15°dH, pH levels ranging from 5.8-6.8, and temperatures maintained at 22-25°C.
