Relevant Information:

This species is monotypic (only member of this genus) and is endemic to Chile. Habitat: It inhabits substrates of silt, fine and coarse sand, gravel and boulders. B. maldonadoi, is vulnerable to predation by introduced species. Aquarium Care: Small temperate and well planted tanks a fine grained substrate with a few hiding places. Do not place larger fish in the same tank. Good filtration is recommended but a powerful current is not recommended. Diet: Their diet consists of benthic aquatic insect larvae, amphipods and mites. In the aquarium, small live, frozen and flake foods. Etymology: The specific name maldonadoi: In honour of Chilean agronomist and agricultural engineer Ernesto Maldonado, Inspector General de Bosques, Pesca y Caza (Forests, Fishing and Hunting), Santiago de Chile, who helped Eigenmann during his 1919 expedition to Chile. Remarks: It is estimated that their abundance is decreasing habitat alteration due to fragmentation, pollution and artificiality.

IUCN Red List

Distributional range of this species is limited to central Chile and it is considered abundant in parts of its range. There is a shortage of reports of resistant and resilient populations, and it is considered a species sensitive to habitat change and pollution. Significant population declines have been documented in rivers in central Chile, where threats will not cease. A past reduction rate of at least 50% is therefore suspected over the last 10-12 years, with this reduction predicted to continue in the future. As such, it is assessed as Endangered, (IUCN 2024).
