No description is available for Corydoras axelrodi.
On the bottom, you prefer to use rounded (filter) sand. They dig through the substrate with their barbels. Using sharp sand or gravel can damage their barbels. The damage causes inflammation where they sometimes even lose their complete barbels. It is, therefore, better to keep them on non-sharp sand. By the way, the barbels grow back slowly as soon as they are kept on sand again.
