No coral is not supposed to go into a new tank. I don't really believe that to an extent. I start out with easy softies once my tanks cycle. If all is well and healthy I go with something that requires more stable water conditions lps. My latest tank has been set up for 6 months, At 4 months I got afew lps, and the last few weeks I added a clam, anenome, and an sps, but I worked up to the more difficult stuff, of course the type lighting you have determines what you can eventually add.
