I am interestedin trying to breed cory cats and have heard its not
necessary to use any substrate but have also heard you need substrate. I
have been told that you can use coarse gravel, builders sand, pieces of
slate or glass, or marbles.

Do they need deep tanks or shallow tanks?

Does anyone here breed corys? Any help is appreciated.
==========================================
I always believed the closer you can get to their natural habitat the
better. I saw a pair of gray cory's spawning in a tank at PetsMart last
week.
