Best substrate for cory cats

Do they need deep tanks or shallow tanks?

Does anyone here breed corys? Any help is appreciated.


I go with sand; pool filter sand is cheap; clean and less abrasive than some
others. watching corydoras barbling through the sand is one of the
pleasures of keeping them. that said I also keep a variety of
rock "beaches" and wood in their tanks as well.

I would not tend to keep them in tanks over 24" as they have a passion for
darting to the surface.

I like species groups in odd number of nine or more.

a cool water change of 25-30% will inevitibly spawn furious breeding
behaviour.
