Uaru is typically found in slow-moving rivers, streams, and flooded forests in the Amazon basin. It prefers warm, soft, acidic water with plenty of vegetation and hiding spots. In the wild, Uaru feeds on algae, plants, insects, and small invertebrates. It is a peaceful fish that thrives in a community tank with other non-aggressive species.


In a home aquarium setting, Uaru should be fed a varied diet that includes high-quality flake or pellet food, frozen or live foods such as bloodworms, brine shrimp, and vegetables like zucchini and spinach. It is important to provide a balanced diet to ensure the fish’s health and vibrant coloration. Uaru is a voracious eater and will readily accept a wide range of foods.


When keeping Uaru in an aquarium, it is important to provide ample space for swimming and hiding, as well as plenty of plants and driftwood for natural grazing behavior.

Breeding Uaru in captivity can be challenging, as the fish require specific water conditions and a well-established tank environment. To encourage breeding, provide the fish with a varied diet, ample hiding spots, and slightly warmer water temperatures.
