Congo Tetra (Phenacogrammus interruptus)

Description

The Congo Tetra is a beautiful and peaceful freshwater fish known for its vibrant colors and long, flowing fins. Native to the Congo River basin in Africa, this species is a popular choice among aquarium enthusiasts due to its striking appearance and relatively easy care requirements.

Appearance

• Body Coloration: Iridescent with a mix of blues, greens, and golds. The colors are more pronounced in males.
• Fins: Males have extended, flowing fins with a distinct violet and white fringe.
• Size: Adult Congo Tetras typically grow to about 3 to 3.5 inches (7.5 to 9 cm) in length.

Habitat

• Natural Habitat: Prefers slow-moving, densely vegetated waters of the Congo River.
• Aquarium Setup: A well-planted tank with plenty of swimming space, subdued lighting, and a gentle water flow mimicking their natural habitat is ideal.

Water Parameters

• Temperature: 73-82°F (23-28°C)
• pH: 6.0-7.5
• Hardness: Soft to moderately hard (3-18 dGH)

Diet

Congo Tetras are omnivorous and thrive on a varied diet. In captivity, they can be fed high-quality flake foods, frozen or live foods such as brine shrimp, daphnia, and bloodworms, as well as vegetable matter.

Behavior and Compatibility

• Temperament: Peaceful and shoaling fish, best kept in groups of at least 6 to 8 individuals.
• Tank Mates: Compatible with other peaceful species. Avoid keeping them with aggressive or fin-nipping fish.

Breeding

Breeding Congo Tetras can be challenging but is achievable under the right conditions. A separate breeding tank with slightly acidic, soft water and fine-leaved plants or spawning mops is recommended. The eggs are adhesive and will stick to the plants. After spawning, parents should be removed to prevent them from eating the eggs.

Maintenance

Regular water changes and maintenance of water quality are crucial for the health of Congo Tetras. They are sensitive to poor water conditions, so keeping the tank clean and stable is essential.

Interesting Fact

Male Congo Tetras are known for their striking colors and finnage, which they use to attract females during the breeding season. The vibrant colors are a sign of good health and proper care in an aquarium setting.
