Last last I had a brain wave and decided to change my white stone gravel to black sand!!! didnt take to long, about 1 1/2 hours. Here is a picture of two of my corys settling in.
Very nice. I know the Cories love it. Nice touch with the white sand in the pots. I just must get into pots! I got some new plants that have tubers and such. They are great little plants. My pandas uncovered them! Sand is not a great potting medium.
