Food and feeding
Ornate corys should accept all foods that are offered. They should be given quality flakes or sinking pellets as their staple diet with the addition of sinking algae wafers. Corydoras ornatus will readily accept a weekly treat of blood worms or brine shrimp.
South America; Ornate corys are to be mostly found along the Rio Tapajos.
When mature the females will be slightly larger, with a stockier outline.
Cooler water changes will induce the spawning. The female will lay 3-4 eggs and carry them in her pelvic fins with the sperm to a spot where she will deposit them. This will be repeated until 100 eggs have been laid. They will hatch after 4-5 days and when the fry are free swimming, they can be fed on newly hatched brine shrimp or Infusoria.
The expected lifespan for Ornate cory is 5-6 years.
Corydoras ornatus belongs to a very peaceful species; as such they make great tank mates for a community set up. They need to be kept in groups of 6 or more.
