Care and Environment
Proper care of the Lake Tebera Rainbowfish involves replicating aspects of its natural habitat to ensure health and vibrant coloration.
What is the minimum tank size for a single Lake Tebera Rainbowfish?
A minimum tank size of 75 liters is recommended to provide adequate space for swimming and to maintain water quality.
What are the ideal water parameters for this species?
Maintain a temperature between 22°C and 26°C, a pH range of 7.0 to 8.0, and water hardness between 10 to 15 dGH.
How should the tank be set up to mimic their natural environment?
Incorporate a heavily planted setup with open swimming areas. Use plants like Java Fern, Anubias, and Vallisneria, along with driftwood and river rocks to create hiding spots. A dark substrate can enhance their coloration.
Ensure a gentle to moderate water flow and use a reliable filtration system to maintain clean, clear water. Regular partial water changes are essential to keep nitrate levels low.
As omnivores, Lake Tebera Rainbowfish thrive on a varied diet. Offer high-quality flake foods, micro pellets, and supplement with live or frozen foods such as brine shrimp, daphnia, and bloodworms to enhance their health and coloration.
Be aware that they are known jumpers; therefore, a well-covered aquarium is necessary to prevent escapes.
Origin and Habitat
Endemic to Papua New Guinea, the Lake Tebera Rainbowfish inhabits the Lake Tebera basin in the Central Highlands. This area comprises interconnected pools, springs, and marshes surrounded by rainforest-covered mountains. The waters are clear and slow-moving, rich in aquatic vegetation, providing ample hiding spots and open areas for swimming.
What type of environment does Lake Tebera provide for these fish?
The lake features clear, slow-moving waters with abundant aquatic plants, offering both shelter and open spaces for the fish.
Are there seasonal variations in their natural habitat?
Specific seasonal variations are not well-documented, but the stable highland environment suggests relatively consistent conditions year-round.
Temperament and Compatibility
Lake Tebera Rainbowfish are peaceful and social, thriving in groups of six or more. Their active schooling behavior adds energy to community tanks.
Can they be kept with other fish species?
Yes, they are compatible with other peaceful, similarly-sized fish such as tetras, rasboras, Corydoras catfish, and other rainbowfish species.
Are there any species to avoid as tank mates?
Avoid housing them with aggressive or fin-nipping species, as this can cause stress and potential injury.
Maintaining a harmonious tank community involves providing ample space and monitoring interactions to ensure all inhabitants coexist peacefully.
Interesting Facts
The Lake Tebera Rainbowfish was first collected for scientific purposes in 1980 and described by Allen in 1981. Males in breeding condition display a distinctive white or bluish stripe on their forehead, signaling readiness to spawn. They are egg scatterers, laying eggs over several days, which hatch within 7-10 days. Fry can be fed infusoria or finely crushed flake food until they are large enough for brine shrimp.
How long does it take for juveniles to develop their full coloration?
Juveniles may take 6-12 months to develop their mature, vibrant coloration.
Are they considered a rare species in the aquarium trade?
Due to their limited geographic range, they are relatively rare and sought-after in the aquarium trade.
