I've always heard about people being really carefull with substrate choices and loaches/corys. I think it has been pretty well decided that lost barbs is a result of poor water quality.

Barbs are extremely sensitive and should be able to determine what is safe and what isn't before they cut them selves.

I have never actually heard of corys being harmed by any substrate.
I would love to hear at least one story!
