Hi-I fell in love with dogfaced puffers two years ago and decided to get into the hobby. I started with freshwater to learn the ropes, but never got around to switching over to my first love. My 55 is still up and running (doing fabulously), but I think the time to switch has come. Originally I thought that a reef tank would be a better fit (smaller fish-less capacity issues), however, a small part of me still really wants a puffer. Could one work in a tank this size, and if so, what could go with it. If the tank is too small, then I will obviously wait on the FOWL. In that case I would love suggestions for steps to switch from fresh to reef. Any suggestions on lighting, liverock and skimmers would be greatly appreciated. Also stocking suggestions would be great. I know that's a lot of questions, but I am just beginning my research and this is where the experts are. Thank you!
