Origin

The Whiptail Catfish (Farlowella acus) is native to the freshwater environments of South America, specifically found in Lake Valencia and the River Torito in Venezuela. These fish thrive in slow-moving waters rich in submerged vegetation, which provides them with both food and shelter.

Short Description

Whiptail Catfish are distinguished by their slender, elongated bodies and peaceful nature. In aquariums, they typically grow to a size of 13-16 cm (5.12-6.3 inches). Due to their timid nature, it is important to choose compatible tank mates. Ideal companions include Corydoras and small characins, which share a similar peaceful temperament. Be cautious with water changes, as this species is sensitive to sudden fluctuations. Instead of large weekly changes, it is advisable to perform 2-3 small changes per week using aged water to minimize stress.

Lifespan

Under optimal conditions, Whiptail Catfish can live for 5-8 years, making them a lasting addition to a peaceful community aquarium.

General Care

Whiptail Catfish prefer soft, slightly acidic to neutral water, with a pH range of 6-7 and water hardness between 3-10°N (53.57-178.57 ppm). They thrive in water temperatures of 24-26°C (75.2-78.8°F). Maintaining stable water parameters and a gentle flow in the aquarium is essential to mimic their natural habitat. A tank decorated with plenty of driftwood and live plants will provide them with hiding spots and grazing surfaces.

Food and Feeding

Primarily herbivorous, Whiptail Catfish should not be fed meaty foods, as this can harm their health. Their diet should consist of algae wafers and fresh vegetable matter. Suitable options include lettuce, cucumber, and peas. Blanching vegetables before feeding makes them easier for the fish to consume. A varied plant-based diet is key to maintaining their health and vibrant coloration.

Sexing

The sex of Whiptail Catfish can be identified by examining the shape of the snout. Males typically have a broader snout covered with short bristles, while females have a more streamlined appearance.

Breeding

Breeding Whiptail Catfish in home aquariums is possible but requires careful attention. The male will select and clean a spawning site, often on the tank glass. The female lays eggs, usually in the evening, and the male takes on the role of fanning the eggs. They typically hatch within 6-10 days. The crucial period begins once the fry hatch; they need to be fed immediately with vegetable matter and Infusoria to ensure survival. Note that Whiptail Catfish fry often have a high mortality rate, so maintaining water quality and providing proper food is vital during this stage.

Additional Notes

Whiptail Catfish are sensitive to water quality and environmental changes. To avoid stress, it is best to perform small, frequent water changes (2-3 times a week) using aged water instead of large weekly changes. This approach helps maintain stable conditions, promoting the health and longevity of these delicate fish.
