Ok, I finished the aquascaping today. It's not so easy to tell but it's in a horseshoe shape. It's amazing how many crevices the fish find to swim through. My purple tang, which is about 4", swam up to what looked like a solid rock part and then disappeared. He turned sideways and went through a small crack!
Anyway, everyone, including me, made it through unscathed. I left foxface in the tank, along with everyone else, and he behaved beautifully! He stayed in one corner while I was doing the other side and then swam to the corner on the other side when I moved across.
