I've thrown some pretty big fits when trying to arrange rocks in my tank. ;D This last weekend I rearranged EVERYTHING just to get my Monti Cap in moderate flow. I hate it. It looks unnatural now. I'll do it again this weekend. : In the past when the whole house of cards came down from my tinkering I've made noises I've never heard before. Do you have any rock stacking stories? Let's hear them!
