Common Longfin Bristlenose Catfish – A Graceful and Practical Aquarium Companion

The Common Longfin Bristlenose Catfish (Ancistrus cf. cirrhosus) is a stunning freshwater species recognised for its elegant, flowing fins and efficient algae-eating capabilities. This hardy and peaceful fish is perfect for aquarists seeking a combination of beauty and practicality. Its low-maintenance care requirements make it ideal for beginners, while its striking appearance appeals to seasoned hobbyists.

Size and Lifespan

The Common Longfin Bristlenose Catfish grows to about 12–15 cm (5–6 inches), including its impressive fins. With proper care, these fish can live up to 7 years or more. Ensuring a clean, stable environment and a balanced diet will help them reach their full potential and maintain their graceful fins.

Ideal Tank Setup

A 120-litre tank or larger is ideal for this species, providing ample space for their flowing fins to move freely. To replicate their natural habitat and ensure comfort:

• Include driftwood and caves for hiding and resting.
• Add live plants to provide shaded areas and enhance the tank’s visual appeal.
• Use soft sand or smooth gravel as a substrate to protect their sensitive barbels.

Water Parameters

• pH Range: 6.5–7.5
• Temperature: 22–28°C
• Filtration: Use efficient filtration to maintain pristine water conditions, as these catfish produce moderate waste.

Compatible Tank Mates

The Common Longfin Bristlenose Catfish is peaceful and thrives in community tanks with other calm species. Excellent companions include:

• Tetras
• Rasboras
• Gouramis
• Corydoras catfish

Avoid housing them with aggressive or fin-nipping fish, such as barbs or large cichlids, as they may harm the catfish’s delicate fins. A single individual or a pair is usually sufficient for most aquariums unless you plan to breed them.

Feeding and Nutrition

While these catfish are excellent algae-eaters, they require a varied diet to remain healthy. Feed them:

• Algae wafers
• Blanched vegetables, such as courgette, cucumber, or spinach
• Sinking pellets
• Occasional live or frozen treats, such as bloodworms or daphnia

Feed them once or twice daily, ensuring that food sinks to the bottom where they can easily access it. Remove uneaten food promptly to maintain water quality.

Breeding and Sexing

Breeding Common Longfin Bristlenose Catfish is relatively straightforward. Males are easily identified by their larger, more pronounced bristles, while females have smaller or no bristles. To encourage breeding:

1. Provide dark caves or hollow decorations for the male to use as a nesting site.
2. Maintain stable water conditions and keep the temperature around 26°C.

The male guards and aerates the eggs, which hatch within 5–7 days. Once hatched, fry can be fed on crushed algae wafers and finely chopped vegetables to support their growth.
