Feeding This species will eat just about any food that sinks down to their level. Flake foods and sinking pellets/wafers make up a good staple diet, for these fish. Frozen and live foods are great as treats.
Furniture Hiding places in the form of caves, driftwood, and plants are appreciated. As these catfish sometimes cavort out in the open, open swimming space is necessary.
Compatibility Very peaceful fish, and will never bother a tankmate. They are completely harmless.
Suggested Tankmates Avoid large or aggressive fish which are not good tankmates for any Corydoras. Small plecos, tetras and dwarf cichlids are good tankmates.
Breeding This cory spawns the way most corys do. The pair will adopt the ''T'' position, and the female will gather eggs and sperm. Then, she swims to a flat, clean surface (usually the glass), and deposits the eggs. This is repeated numerous times.
Breeding Reports There is but a single breeding report, read it here.
