Lays sticky eggs on the glass and plants after a cool water change.
Keep a group of 6 or more with extra males. Females are rounder and larger.
A 10-20 gallon (40-75 L) tank with fine sand, plants and a sponge filter. Add a spawning mop or plants. 22-26 C.
A big cool water change (rain simulation) after a few days of rich food.
Females place 1-4 eggs at a time over a spawning of several hours, up to about 25 eggs in total; eggs hatch in 3-5 days.
Feed microworms and baby brine shrimp. Remove eggs to a hatch tray. Keep water cool and clean.

The story of the panda corydoras
