Short Description

The Olivegreen Ufipa Barb (Barbus olivaceus) is a peaceful and vibrant freshwater fish native to the rivers of Tanzania. Unlike some barbs known for their aggression, this species thrives in community tanks with other non-aggressive fish. These active middle-level swimmers are best kept in small groups and require a varied diet to maintain their health and coloration. Their adaptability and calm temperament make them a popular choice for aquarists.

Origin

Native to Africa, the Olivegreen Ufipa Barb is found in the rivers of Tanzania. These environments are characterized by soft to moderately hard water and a mix of submerged vegetation, making them ideal for this species.

Tank Requirements

A tank of at least 60 liters (15 gallons) is recommended for Olivegreen Ufipa Barbs. Maintain water temperatures between 23-28°C (73.4-82.4°F), a pH range of 6.5-7.5, and water hardness of 6-16°N (107.14-285.71 ppm). Include plants, driftwood, and smooth rocks for decoration, leaving plenty of open swimming space. Slow water flow replicates their natural habitat. Regular water changes are essential to maintain water quality and keep the fish healthy.

Food and Feeding

Olivegreen Ufipa Barbs are omnivorous and accept a variety of foods. Provide high-quality flakes or pellets as their staple diet, supplemented with live or frozen treats such as brine shrimp and bloodworms. Adding vegetable matter, such as blanched spinach or zucchini, ensures a balanced diet. Feed them small portions twice daily to prevent overfeeding and maintain water quality.

Compatibility

These peaceful barbs are ideal for community tanks. Suitable tankmates include small tetras, rasboras, and Corydoras catfish. Avoid pairing them with aggressive or much larger species that may cause stress. Keeping them in groups of six or more encourages natural shoaling behavior and reduces stress.

Sexing

Sexing Olivegreen Ufipa Barbs is challenging as there are no prominent physical differences between males and females. Observing subtle behaviors during breeding periods may help identify genders.

Breeding

Olivegreen Ufipa Barbs are egg scatterers, and their breeding process involves laying eggs across plants, substrate, and tank surfaces. To breed them, move a pair into a dedicated breeding tank in the evening. Eggs are typically laid overnight and hatch within 24 hours. The fry should initially be fed infusoria twice daily, transitioning to newly hatched brine shrimp after the first week. Providing plenty of hiding spaces in the breeding tank can help protect the eggs and fry from predation.

Lifespan

With proper care, Olivegreen Ufipa Barbs can live up to 5 years. Maintaining a clean and stable environment, along with a nutritious diet, is crucial for their longevity.
