Prior to description, this species was traded under various code numbers, distinguished by the presence of light-colored spots on the entire body and head, and an unplated abdomen. Baryancistrus Xanthellus belongs to the Loricariidae family, the largest among catfishes, with distinct characteristics separating it from congeners.

Habitat and Distribution

Endemic to the rio Xingu basin in Brazil, Baryancistrus Xanthellus prefers whitewater rapids, with adult specimens found under submerged rocks and boulders. Sharing habitats with various species, such as Baryancistrus aff. niveatus and Ancistrus spp., it inhabits a specific section of the Rio Xingu known for its unique features.

Aquarium Setup

To replicate its natural habitat, a tank for Baryancistrus Xanthellus should resemble a flowing river with rocks, gravel, water-worn boulders, driftwood, and tough aquatic plants like Microsorum and Anubias. Bright lighting encourages aufwuchs growth, a vital part of its diet. Consistent pristine water quality, oxygen levels, and water movement are essential, necessitating regular maintenance and suitable filtration systems.

Behaviour

While juveniles are relatively peaceful, adult males display aggression towards conspecifics and other territorial threats. They are best kept with species that inhabit other areas of the tank, requiring sufficient territorial space and visual barriers when sharing a habitat. In large tanks, cautious combinations with other catfish species may be possible with proper planning.

Feeding and Diet

Wild specimens of Baryancistrus Xanthellus primarily feed on algae like diatoms and filamentous genera, supplemented by invertebrates such as chironomids and bryozoans. In captivity, a diet should include sinking dried foods, bloodworms, fresh fruits, vegetables, and occasional prawns. Home-made gelatine-bound recipes are recommended to ensure a diverse nutrient intake.

Reproduction & Dimorphism

Limited information exists on the breeding of Baryancistrus Xanthellus, with successful attempts contingent on large tanks, well-oxygenated water, and a high-quality diet. Sexual dimorphism is evident in adult males through a broader head profile and longer pectoral-fin spines compared to females. Successful breeding efforts require meticulous attention to environmental and dietary factors.
