First, thanks to those who helped me out on my previous questions
. Being that I'm considering some cories for the tank, I was wondering what your feelings were on substrate. I am not using live plants so I was going to use gravel for the bottom. But I'm afraid that it may damage their barbs. I know sand may be an option, but I don't have enough experience with this to worry about harming the filter and the gases under the sand. What do you think of this.....http

It seems to have more rounded corners, but the size is hard to tell from the pictures. Thanks in advance.
