Natural habitat

The Royal Farlowella is primarily found in the fast-flowing rivers of Central and South America. This species thrives in well-oxygenated waters and prefers slightly cooler temperatures. The natural habitat involves a substrate that consists of gravel along with ample driftwood and plants to mimic its native environment.

Where they are found

Native to the Orinoco River basin, the Twig Catfish thrives in soft and slightly acidic waters.

Aquarium care

Maintain a stable environment with a strong filtration system to replicate its natural habitat. Regular water changes are vital to keep ammonia and nitrite levels low. Use driftwood and crianthal plants to offer hiding spaces for this species, as they are nocturnal.

Feeding

A primarily vegetarian species, Twig Catfish require algae wafers and tablets complemented with vegetables like courgette and spinach. While they can consume meaty foods, a vegetable-based diet is crucial for their health.

Compatibility

Twig Catfish are peaceful and can coexist with small to medium-sized fish that thrive in soft water, like Corydoras and tetras. They should not be housed with aggressive species that might outcompete them for food.

Breeding

Breeding Royal Farlowella can be straightforward with proper conditions. A pair should be kept in a well-maintained tank with good water quality. They typically lay about 150 eggs on flat surfaces, requiring moderate water flow for optimal development.
