Sand it is b/c thats what I got today. YaY me. My bf has some big river rock so I might add that in and see how it looks first. Then later on I ll add the other rocks I prob. use the tree stumps for the time being. =) Thanks that gave me ideas to mix those around. Yah I am going to do another Afican tank, this time I am gonna look for more rare africans possibly. I am bringing a list to the lfs in hope he can get them in =)
