    IDK - I know you're set on sand but I've owned corys from the beginning and have always had gravel - never had problems - it's smooth - they can dig in it just like sand. IMHO I don't think it's a requirement but they're probably happier with sand.

    +1 to Imma24.

    sure, it can be interesting watching the cories dig around in sand and have it puff out their gills and whatnot, but from an animal welfare perspective
    as long as the substrate is clean and not large enough for food to fall through the cracks, the cories likely cannot care less. cories don't dig for fun, they do so to find food.
    the abrasion thing also is a myth. a dirty substrate or possibly also body flukes is what causes barbel abrasion. my cories live on flourite and they have 1/4 inch barbels.

    I kind of know where you're coming from - but cories dig and sift in sand as part of their normal, habitual behaviour. It's what makes them a corydoras. Preventing them from doing that, arguably, may cause stress. Possibly a more extreme example but you might compare it to keeping a horse but not allowing it to graze.

    It's obviously your choice - I'm just telling you from my experience. I have kept cories since my tank started with no problems - however, if I had to do things over, I would probably do a sand substrate because I would guess the bottom feeders appreciate it more and the other fish don't care.

    @ firefly
    I respect your opinions and experiences. I am just speaking from my own experiences of keeping corydoras over gravel substrates, in that they do not show any sign of stress. Of course, we never will be able to know for sure, so this conclusion is based on their activity, coloration, growth, breeding frequency, etc which have always been excellent for me.
