I have a 29 Gal. tank w/ some live rock. The only fish I have is a small yellow tang. I'm really wanting to start having corals and things, but not sure how to go about starting to move in that direction. I was wondering if mushrooms and zoas are the way to start. If not, what are the easiest corals to start with? I have coralife 50/50 bulbs and a Penguin 350 w/ double biowheel. I'll be at the Chatt Frag swap and wondering what I should look for there. Any advise would be appreciated.
