- Water Conditions: Orange Congo Tetras thrive in well-maintained aquariums with stable water conditions. They prefer a temperature range of 75°F to 82°F (24°C to 28°C) and a slightly acidic to neutral pH level of 6.0 to 7.5. Good water filtration and regular water changes are important to ensure optimal water quality.

- Tank Size and Setup: Provide a spacious aquarium for Orange Congo Tetras, as they prefer swimming freely. A tank size of at least 30 gallons (113 liters) is recommended for a small school of these fish. Create a natural environment by incorporating plants, driftwood, and rocks. Adequate hiding places and open swimming areas should be available to mimic their natural habitat.

- Tank Mates: Orange Congo Tetras are generally peaceful and can be kept with other peaceful community fish. Suitable tank mates include other tetra species, rasboras, peaceful barbs, and small to medium-sized catfish. Avoid housing them with aggressive or fin-nipping fish that may stress or harm them.

- Feeding Habit: Orange Congo Tetras are omnivorous and have a preference for small-sized foods. They readily accept high-quality dry foods such as flakes or micro-pellets. Supplement their diet with live or frozen foods such as brine shrimp, daphnia, and bloodworms to provide essential nutrients and variety.

- Care and Behavior: Phenacogrammus aurantiacus requires attentive care to thrive. They prefer a peaceful aquarium environment with suitable tank mates. Providing them with proper water conditions, a balanced diet, and regular maintenance, including water changes, are essential for their well-being.

- Breeding: Breeding Orange Congo Tetras can be challenging. Creating specific breeding conditions, such as soft, slightly acidic water and the presence of fine-leaved plants, may encourage spawning behavior. Separating breeding pairs into a dedicated breeding tank can increase the chances of successful reproduction. Remove the adults after spawning to protect the eggs and fry.

In conclusion, Phenacogrammus aurantiacus, or Orange Congo Tetra, is a strikingly beautiful fish species that can elevate the visual appeal of your aquarium. With their vibrant colors, peaceful nature, and graceful swimming, they create a captivating display. By providing suitable water conditions, compatible tank mates, and a varied diet, you can ensure the health and vibrancy of these tetras in your aquarium.
