They breed best in larger groups. One trio laying eggs tends to trigger the others. Give them a large shallow tank. Add two trays of ice cubes (simulates rainfall) and watch them breed in the morning. They lay eggs on the glass or your filter stems. Remove the parents or the eggs. Use a single-edged razor blade to (carefully) slice off the eggs after they harden and put them in a half-filled pre-prepared tank. Newborn catlets make very tasty snacks.

Mature females grow longer (and wider) than the males. The rounded belly of the female keeps her nose off the gravel when she rests. They usually take two years to attain breeding size, but some breed earlier. Corys live several years. From Ackerz Ackerz 2008-05-01
