They say it's not preferable. But they'll be fine. All the pet stores have it and so do I. Perhaps others will disagree.

Big gravel tends to wear their barbels down. they prefer sand.

I have 5 cory cats in a 20 gal. long with regular gravel and they are doing great. I think they have a better chance of damaging their barbels in a gravel tank, but they will be fine!
