3" Xingu Peacock Bass

3" Xingu Peacock Bass – Majestic Freshwater Predator for Your Aquarium

The 3" Xingu Peacock Bass is a stunning and powerful addition to any freshwater aquarium enthusiast’s collection. Known scientifically as Cichla xinguensis, this species is native to the Xingu River basin in Brazil and is prized for its vibrant coloration, active temperament, and impressive size. If you’re considering adding this impressive fish to your tank, understanding its care requirements, temperament, and compatibility is essential for success.

Size and Growth Potential

At 3 inches, your Xingu Peacock Bass is a juvenile, but it will grow considerably over time. Adult specimens can reach up to 20 inches in length in the wild, though in captivity, they typically max out around 12 to 15 inches depending on tank size and diet. This rapid growth means providing ample space and proper nutrition is critical to keep your fish healthy and thriving.

Temperament and Behavior

The Xingu Peacock Bass is a predatory and territorial cichlid, known for its bold and active nature. While generally not aggressive towards much larger tank mates, it can exhibit territorial behavior especially in confined spaces. Understanding its temperament helps aquarists avoid conflicts and create a balanced community tank. They are intelligent, curious fish that often recognize their owners and can become quite interactive in a home aquarium.

Recommended Tank Size

Due to their eventual size and active swimming behavior, a minimum tank size of 125 gallons is recommended for a single adult Xingu Peacock Bass. Larger tanks of 180 gallons or more are ideal if you plan to keep multiple specimens or other large fish. Providing plenty of open swimming space combined with hiding spots mimics their natural riverine environment and reduces stress.

Optimal Water Parameters

• Temperature: 75°F to 82°F (24°C to 28°C)
• pH: 6.0 to 7.5 (slightly acidic to neutral)
• Hardness: Soft to moderately hard water (2–15 dGH)

Maintaining clean, well-filtered water with stable parameters is essential. This species thrives in oxygen-rich water with moderate current, replicating their native river habitat.

Diet and Feeding

In the wild, Xingu Peacock Bass are carnivorous predators feeding primarily on smaller fish and crustaceans. In captivity, they accept a variety of meaty foods including live feeder fish, frozen shrimp, and high-quality pellets formulated for carnivorous cichlids. Feeding a varied diet supports vibrant coloration and robust growth. It’s important to avoid overfeeding and maintain a feeding schedule of 1-2 times daily.

Tankmate Compatibility

Because of their predatory nature and size, choosing tankmates carefully is crucial. Suitable companions include large, robust fish such as large plecos, silver dollars, and other sizable South American cichlids. Avoid small fish species which will be viewed as prey. Providing plenty of space and visual barriers in the tank can reduce aggression and territorial disputes.
