Care Guide
Diet
Feed sinking pellets and algae wafers as a staple diet, supplemented with live or frozen foods such as bloodworms and brine shrimp 2-3 times per week. These bottom feeders will also consume leftover food from other tank inhabitants. Ensure food reaches the substrate where they feed.
Behavior
David Sands' Corydoras are active bottom dwellers that spend most of their time sifting through substrate searching for food. They are social fish and should be kept in groups of at least 4 individuals to exhibit natural schooling behavior. They are peaceful and non-aggressive toward other tank inhabitants.
Breeding
Breeding in captivity is possible but challenging. They require cooler water temperatures (around 68-72°F) and a well-established tank with plenty of hiding spots. Males will pursue females, and eggs are typically laid on hard surfaces or plants. Remove eggs to a separate breeding tank for best success rates.
