I'm looking for advice on what might to well in a new tank. My Red Sea Max Nano is 2+ weeks post cycle and I put a pair of MochaVinci clowns in last week. I want to start adding some coral but don't want anything that won't do well in a virtually sterile tank. My overall goal includes zoas, corralimorphs and one Euphyllia. I started the tank with Marco Rocks dry rock and about 1" of sand. What's the best/safest next step?
