Hello there! I absolutely love panda cories, and would love to get some for my first tank (a 20 gallon that is currently cycling). But I have a gravel substrate, and have heard that this is not very good for their barbels.

Is that true? Or can panda cories thrive on gravel? The gravel isn't especially sharp, but it's not exactly smooth either. If they can't have gravel, what is the best way to change to sand without disturbing the cycling tank too much? Also, what kind of sand do you recommend?

Thanks very much for reading, and any help or advice would be appreciated.

I keep Corys in a 20gal with gravel, and they don't seem to have any problems. And my gravel sounds like yours, not sharp but not real smooth either.
