Common Name: Temensis Peacock Bass
Scientific Name: Cichla temensis
Other Names: Speckled Peacock Bass, Peacock Cichlid, Tucunaré
The Temensis Peacock Bass is one of the largest and most striking species of peacock bass, known for its impressive size, vibrant coloration, and aggressive predatory behavior. This fish is highly prized by both sport fishermen and aquarists for its beauty and challenge in catching or keeping.
Habitat and Distribution:
The Temensis Peacock Bass is native to the river systems of South America, particularly the Amazon and Orinoco River Basins, including countries like Brazil, Venezuela, and Colombia. These fish inhabit slow-moving rivers, floodplains, and lagoons with plenty of submerged vegetation and structures, providing excellent hunting grounds.
Size and Lifespan:
In the wild, Temensis Peacock Bass can grow up to 3 feet (90 cm) in length and weigh over 30 pounds (14 kg). In captivity, they typically reach around 24-30 inches (60-75 cm) with proper care. With optimal conditions, their lifespan can range from 10 to 15 years.
Diet and Behavior:
Temensis Peacock Bass are carnivorous, feeding primarily on fish, crustaceans, and other meaty foods in their natural habitat. In an aquarium, their diet should include high-quality carnivorous pellets, live or frozen foods such as fish, shrimp, and crayfish. They are known for their aggressive and territorial behavior, making them formidable predators. They require a large and dynamic environment to thrive and exhibit natural behaviors.
Breeding and Reproduction:
Breeding Temensis Peacock Bass in captivity can be challenging due to their size and specific environmental requirements. In the wild, they spawn in shallow waters during the rainy season. The female lays eggs on a flat surface, and both parents guard the nest aggressively. To encourage breeding in an aquarium, provide a spacious tank with plenty of flat surfaces for spawning, maintain optimal water conditions, and simulate seasonal changes. Successful breeding typically requires a very large, well-maintained tank.
Aquarium Care and Tank Requirements:
Due to their large size and aggressive nature, Temensis Peacock Bass require a very large aquarium, with a minimum of 300-500 gallons recommended for adult specimens. The tank should have a sandy or fine gravel substrate to prevent injury, and include plenty of hiding spots and open swimming areas. Efficient filtration and regular water changes are essential to maintaining water quality. The water temperature should be kept between 75-82°F (24-28°C), with a pH of 6.0-7.5 and soft to moderately hard water.
Ideal Tank Mates:
Temensis Peacock Bass can be kept with other large, robust fish that share similar water parameter requirements. Suitable tank mates include large cichlids, arowanas, and similarly sized catfish. Avoid housing them with small or delicate species that may become targets of predation.
Difficulty Level:
Advanced. Keeping Temensis Peacock Bass requires a deep understanding of their needs, including their large size, predatory behavior, and specific water quality requirements. They are best suited for experienced aquarists with the space and resources to provide proper care.
