Origin and Distribution

Kelberi Peacock Bass originates from the freshwater rivers and lakes of Brazil, particularly in slow-moving waters with abundant prey. Unlike other Peacock Bass species, Kelberi can tolerate smaller aquarium spaces, making them a preferred choice for home aquariums among Peacock Bass enthusiasts.

Colors and Markings

Kelberi Peacock Bass are known for their golden-yellow body with black spots and vertical bands. Their red or orange eyes give them an intense look, while mature males may develop a nuchal hump. Their metallic golden shine makes them one of the most visually appealing Peacock Bass varieties.

Tankmates and Compatibility

Kelberi Peacock Bass are aggressive predators, so tankmates must be chosen carefully. They do well with:

• Other large predatory fish (Arowanas, Large Catfish, Giant Gourami)
• Large Cichlids (Oscar Fish, Jaguar Cichlid, Green Terror)
• Stingrays (if tank size allows)
• Plecos or armored catfish (as bottom dwellers)

Avoid keeping them with smaller fish, as Kelberi will see them as food. They also do not do well with overly aggressive fish that may challenge their dominance.

Tank Requirements and Care

To keep Kelberi Peacock Bass healthy and thriving:

• Minimum tank size: 125 gallons for juveniles, but adults require 250 gallons or more.
• Strong filtration system to handle their high bioload.
• Good water flow to mimic their natural river habitat.
• Fine sand or gravel substrate with driftwood and rocks for hiding spots.
• Dim lighting to reduce stress and enhance coloration.

Regular water changes (30-40% per week) are crucial to maintaining clean and stable conditions.

Diet and Feeding

Kelberi Peacock Bass are carnivorous predators, requiring a diet rich in high-protein foods. Suitable options include:

• Live fish (guppies, mollies, feeder fish) – but must be quarantined to prevent disease.
• Frozen or fresh seafood (shrimp, tilapia, whitefish)
• Insects and worms (crickets, mealworms, earthworms)
• Pellets and prepared food (high-quality carnivore pellets)

For better health, train them to eat prepared foods like pellets and frozen shrimp instead of relying solely on live prey. Feed once or twice daily.

Gender Differences

• Males: Larger, more vibrant in color, and may develop a nuchal hump.
• Females: Slightly smaller with a rounder belly.

Breeding Kelberi Peacock Bass

Breeding Kelberi Peacock Bass is challenging but possible in large tanks or ponds:

• Pair selection: Choose a mature bonded pair.
• Spawning site: Provide flat surfaces (rocks, driftwood) for egg laying.
• Water temperature: Maintain at 28°C – 30°C (82°F – 86°F).
• Egg care: Parents may guard the eggs aggressively.
• Fry care: Feed newly hatched brine shrimp and small feeder fish.

Common Health Issues

Like other large fish, Kelberi Peacock Bass can suffer from:

• Hole-in-the-Head Disease (HITH) – Caused by poor water quality and lack of nutrients.
• Parasitic infections – Avoid feeding wild-caught feeder fish.
• Fin rot and bacterial infections – Ensure clean water and stable conditions.

Regular tank maintenance and a high-quality diet prevent most health problems.
