Keeping Corydoras Julii (Julii Corys) involves providing a soft, sandy substrate, plenty of hiding spots with plants/wood, a group of 6+, stable warm (22-28°C) water, and a varied diet of sinking pellets supplemented with live/frozen foods, as they are peaceful, schooling bottom-dwellers needing clean water and gentle filtration. Replicating their South American habitat with shaded areas and moderate water flow helps them thrive.
