A beautiful and larger growing species ofCorydorasonly recently introduced to the hobby, CW049 Black Diamond Cory is found in the upper Rio Negro and Uapes drainages along the Brazil/Colombia/Venezuela border. An inhabitant of soft, acidic, shallow waters on fine sand substrate, they are typically found in large aggregations, sometimes mixed with the very similar CW051. Peaceful, hardy, and active, this species makes a striking addition to a community or planted aquarium. Like allCorydoras, they will do best on a fine sand substrate and should be kept in groups of 5 or more.
