Short Description

The Lake Tebera Rainbowfish (Melanotaenia herbertaxelrodi) is a stunning freshwater species native to the highlands of Papua New Guinea. Known for their vibrant colors and peaceful temperament, these fish thrive in community tanks and are a favorite among rainbowfish enthusiasts. They require a well-maintained environment to exhibit their best coloration and natural behaviors, making them a rewarding choice for aquarists.

Origin

As their name suggests, Melanotaenia herbertaxelrodi is endemic to Lake Tebera, a highland lake in Papua New Guinea. This remote and unique habitat is characterized by cool, clear waters and abundant vegetation, providing the perfect environment for this rainbowfish to flourish. The species’ limited geographic range makes it a rare and sought-after addition to aquariums.

Tank Requirements

A tank of at least 80 liters (20 gallons) is recommended for Lake Tebera Rainbowfish. Maintain water temperatures between 21-24°C (69.8-75.2°F), a pH range of 7-8, and water hardness of 8-18°N (142.86-321.43 ppm). Provide plenty of swimming space along with plants and decorations to replicate their natural habitat. Moderate water flow and excellent filtration are essential to maintain the high water quality required for their vibrant coloration.

Food and Feeding

Lake Tebera Rainbowfish are omnivorous and thrive on a varied diet. Offer high-quality algae-based flakes or pellets as their staple food, supplemented with live or frozen treats such as brine shrimp, bloodworms, and daphnia. Feeding them small portions twice daily ensures their health and enhances their coloration.

Compatibility

These peaceful fish are ideal for community tanks. Suitable tankmates include other rainbowfish, tetras, peaceful barbs, and Corydoras catfish. Avoid housing them with aggressive or territorial species that may cause stress. Keeping them in groups of at least six individuals promotes schooling behavior and reduces stress.

Sexing

Males are more brightly colored than females and have a deeper belly, particularly during the breeding season. Observing their physical differences becomes easier as they mature.

Breeding

Breeding Lake Tebera Rainbowfish requires a separate breeding tank equipped with Java moss or spawning mops. Males in spawning condition display a white or blue stripe on their heads. After spawning, remove the eggs to a separate tank to prevent predation by the parents. Eggs are laid over several days and hatch within 7-10 days. Feed the tiny fry infusoria or liquid fry food initially, transitioning to crushed flakes or brine shrimp as they grow.

Lifespan

With proper care, Melanotaenia herbertaxelrodi can live for 3-5 years. Providing stable water conditions, a balanced diet, and a stress-free environment are key to their longevity.
