I had to downsize from a 36 bowfront to a 20-gallon, so I have a *lot* of rock. I can't 'see' what should go where well, and I want enough live rock to help filter, but also like some of the more open designs. I have mostly small frags and I try to make some low, mid, and high areas for them. I just can't seem to find an arrangement that 'clicks. Right now I am 'committed to three of these pieces. The one on the left is 'L'-shaped and really looks cool by itself and has some nice holes. The one on the right is Cyphastrea encrusted, and the one right by it but towards the back has some zoas attached directly to the rock. I probably have this much rock set aside for the day I can get a bigger tank. I have not had much luck with reef putty and such, so I stack naturally.
This is how it is now. Pardon some of the GHA, I am slowly winning that battle.
