I recently got some cories for my tank and am loving them! I have a mix of pygmy, julii and peppered. They are getting along splendidly and swim all over the place with each other. I have a gravel substrate right now and have read about how it might damage their barbels. Been thinking about switching to a sand substrate to make them more at home. How tedious of a task is this going to be? Any advice would be wonderful! Thanks.
