Uaru Cichlid

The Uaru Cichlid, also known as the Triangle Cichlid, is a striking South American cichlid native to the Amazon and Orinoco river basins. Juveniles display a distinctive pattern of large black spots on a silver-gray body, while adults develop a more subdued but elegant coloration with a prominent lateral line and subtle iridescent sheen. Uarus are fascinating because they are one of the few cichlids that are primarily herbivorous, requiring substantial vegetable matter in their diet. They have a unique body shape that is laterally compressed and somewhat triangular, giving them their common name. Uarus are relatively peaceful for their size but require large tanks due to their adult dimensions. They are known for being quite hardy and adaptable, making them a good choice for aquarists looking to keep larger South American cichlids. Their vegetarian diet and manageable temperament make them different from many other large cichlid species.

Care Requirements

Tank Setup

Uaru Cichlids need a spacious aquarium of 75-100 gallons due to their large adult size. They appreciate planted tanks but will eat most aquatic vegetation, so use hardy plants or provide plenty of vegetable matter in their diet to deter plant eating. Large driftwood pieces and rocks create territories. Excellent filtration is essential for maintaining water quality.

Water Quality

• Temperature: 75-82°F (24-28°C)
• pH: 6.0-7.0
• Water Hardness: Soft to moderate, 2-12 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm

Feeding

These primarily herbivorous cichlids require a diet rich in vegetable matter. Offer spirulina-based pellets, blanched vegetables like spinach and zucchini, and leafy greens. Supplement with occasional protein treats like bloodworms or brine shrimp. Feed twice daily with vegetable matter making up the majority of their diet.

Behavior & Compatibility

Uaru Cichlids are generally peaceful for their size but should be kept with other large, robust fish. They can be kept in pairs or small groups in very large tanks. Avoid housing with small fish that could be eaten or delicate species. They are relatively sedentary compared to more active cichlids and spend much of their time grazing.

Tips for Success

• Provide substantial vegetable matter in their diet to prevent plant eating
• Use hardy plants like Anubias and Java Fern if you want vegetation
• Their large size produces significant waste; maintain robust filtration
• Can be kept in pairs in sufficiently large tanks
• Regular water changes help maintain the clean water they prefer
• Juvenile coloration with large spots is quite different from adult appearance
• Their herbivorous nature makes them unique among large cichlids
