I have been planning to start a saltwater tank for a while, and I'm planning to set it up within a year. I'm going to get a 40 gallon tank with all of the filtration provided by live rock and a protein skimmer. I think that I'll use a deep sand bed, but i'm not sure. The fish I plan on keeping are 2 percula or occelaris clownfish, 1 or 2 firefish, 1 bangaii cardinalfish, and (maybe) 1 coral beauty angelfish. After a while I will add a cleaner shrimp (Lysmata amboinensis). Eventually I will add a few corals. These include zoanthids, mushroom corals, and star polyps. Ive done a lot of research but I want to know if I have any compatability issues here. Also, I can find no reliable information on the number of firefish per tank. Any help would be greatly appreciated! *BOUNCINGS
