The reefcentral SF Bay area forum is cool but 90% of it is Buy/Sell/Trade. I'm also interested in a frag tank. All these zoa frags are taking up space in my tank. It just make sense to me. Sometimes I'm not ready or haven't found a spot for a coral yet so I want them on the rack somewhere but I don't want things to disrupt the "natural" look of my display tank. Or if I want to get ready for a frag swap or sell frags it'd be nice to keep frags there. When I have time maybe I'll set up a small satellite frag tank and plumb it to my main tank.
