These are one of the corys that I have had spawn, use a group of at least six of them in a smallish tank, 10-20g, condition them with high quality flake food, brine shrimp, black or tubifex worms, and minced earthworms, Use a well planted tank, riccia and java moss are great. Keep the tank at about 80-82 degrees, ph 6.8-7.0. then when the females are plump do a larger than normal water change (50%) using water that is about 72 degrees F and around 6.4 pH. Set the heater at 78 F. they should spawn the next day. The females stick an egg at a time to plants and are done in 2-3 hours after laying 40-60 eggs. You can leave the parents in the tank as long as you don't starve them. Eggs are susceptible to fungus so a touch methylene blue helps at this stage. Eggs hatch in 4-6 days @ 78 F and fry start feeding about 3-4 days later, powdered flake food works and they will feed on the surface of your sponge filter as well, they can be breeding adults them selves in 6 months.
