Diet

 * As with most Corydoras, these fish will eat most food which sinks to the bottom of the tank. Sinking algae pellets should be supplemented with flake food or other sinking foods like catfish pellets.
 * Be aware these fish do have a carnivorous side to them and love foods such as Bloodworm and Brine Shrimp. Vegetable-based foods offer little nutrition to them. They will also eat any dead, dying, or even injured fish, that sit on the substrate too long. They're very opportunistic!

Breathing

 * In these fish the posterior intestine is modified to function as an air breathing organ by being air-filled, thin-walled and highly vascularized. This means the fish often comes to the surface to swallow gulps of air and passes this to its rear intestine to supplement its oxygen intake via its gills.
