Thank you a ton! I don't know what flaky gravel I could use unless I could find something with a lot of mica in it. I was thinking that the gray cement might look better with the black fluorite substrate I would like to use, then with possibly some natural looking FW
gravel and some PFS perhaps? I don't particularly want the rock work to stand out, I just want it for the fish to hide in. I was also thinking of building it in layers to make more nooks and crannies and then gluing it all together. I realize that I wouldn't be able to rearrange it if I did that but since I want to use live plants I don't think that I will be doing much rearranging anyway. Your thoughts are greatly appreciated!!
