Crafish and other bottom dwellers-possible?

[KyleBradley]

I am fond of corydoras because of the great job they do of keeping the gravel clean, but are they compatible with crayfish, or will it be an inevitable demise of the peaceful catfish?

corys + crayfish sounds like a bad idea to me because cray fish eat well fish

Your cories will soon be food once the crays get big enough to catch them.
