I had a 2.5 deco and although the coraline is good and pretty, I would put my tuxedo urchin to clean it off the walls for me and then transfer him back home to my bigger tank. Rics, GSP, hairy mushrooms, and zoos worked for me. I have some neon green star polyps and some frags of aqua blueish palys if you are interested. I live in SA but drive up to Pflugerville 1 or 2 times a wk. PM me if interested.
