Which dark sand substrate for cories (and plants)?
I'm looking for a dark sand substrate that would work for plants but also be cory safe. I've used flourite, flourite black, and onyx sand in the past but haven't kept cories on them.
If there is a substrate that is also good for plants, that would be great. If the only options are inert sands, I can always augment the substrate with root tabs. I know many people use BDBS, but I was concerned that it would be too rough for cories.
Thank you for your time and help!
