I have had beach rock for my South American Cichlids and recently moved and changed up to a bare bottom. I did so because I thought it would be easier to keep clean, which it is, but it feels boring and not so great looking. So now I am thinking of getting sand. Not sure how easy it will be since the tank is already filled with water and fish, but I would like to hear other peoples opinion of what they like and why before I decide. Wish I could show some pictures of the beach rock cause I love the way it looked but all my pictures are about 2 MB and too big to upload on this site.
