I just upgraded to a 54gal corner with about 40lbs rock, 3in sand, 2 False Perc Clowns, a sixline, and Royal Gamma. I started adding corals but being such a novice I am taking it slow. Right now I have a nice Green Star Polyp, zoos, many Purple, Green and Blue shrooms and my favorite blue Ricordea. My addiction started when my nieghbor gave me his 30gal quarantine tank when he moved. Ever since my 6year old son and I have been crazed reefers. I wish I skipped the 54gal and went right to a 90gal.
