Short Description

The African Spotscale Barb (Barbus holotaenia) is a peaceful and active freshwater fish native to Central Africa's river systems, such as the Congo and Ogowe. Known for their vibrant coloration, these fish truly stand out when displayed against dark substrates and backgrounds. They thrive in well-conditioned water and need a spacious tank with plenty of open swimming areas. Low, bushy plants and driftwood help soften the water and create a natural environment that mirrors their habitat.

Origin

Endemic to Central Africa, African Spotscale Barbs are found in river systems such as the Congo and Ogowe. These rivers are characterized by soft, slightly acidic water with a rich array of submerged vegetation, making it an ideal environment for this species.

Tank Requirements

African Spotscale Barbs require a tank of at least 150 liters (40 gallons) to provide ample swimming space. Maintain water temperatures between 23-30°C (73.4-86°F), a pH of 6-6.5, and water hardness of 4-12°N (71.43-214.29 ppm). Use fine sand or smooth gravel as substrate and decorate the tank with driftwood, low bushy plants, and some open areas for swimming. Ensure good filtration and water flow to replicate their natural riverine habitat, along with regular water changes to maintain pristine conditions.

Food

The African Spotscale Barb is carnivorous and primarily feeds on insects and larvae in the wild. In captivity, they can be fed a varied diet of high-quality pellets or flakes supplemented with live or frozen foods such as brine shrimp, bloodworms, and insect larvae. Feeding them twice daily in moderate portions will help maintain their health and coloration.

Compatibility

African Spotscale Barbs are peaceful and make excellent additions to community tanks. They can be housed with other non-aggressive fish of similar size, such as Congo Tetras, other barbs, or peaceful cichlids. Avoid keeping them with overly aggressive or significantly smaller species. Keeping them in groups of five or more will encourage natural schooling behavior and reduce stress.

Sexing

Sexual dimorphism is not well-documented in African Spotscale Barbs. Further observation and research may reveal subtle differences between males and females during breeding periods.

Breeding

Breeding African Spotscale Barbs in captivity is rare and challenging. In the wild, they are known to spawn during the rainy season, likely through egg scattering among plants or debris. Mimicking rainy season conditions by gradually lowering and raising water levels and providing soft, acidic water may encourage spawning. If breeding is successful, the eggs should be removed to a separate tank to prevent adults from eating them. Feed the fry infusoria or finely powdered fry food until they are large enough to consume larger items.

Lifespan

With proper care, African Spotscale Barbs can live for 5-7 years. Ensuring stable water parameters, a nutritious diet, and a stress-free environment is essential for their longevity.
