I have a 20 gallon nano tank, with about 30lbs of rock and 2 fish and a cb shrimp, im stuck on what corals i could put in, theres no sand bed, and little floor surface, mainly rock work, but can anyone help me find some corals out that will do great in the tank?

Mushrooms, zoas, (be sure to dip them in an appropriate coral dip) green star, kenya tree, etc, should do nicely in small scale. THey require moderate light, 1.025 salinity, 8.3 alkalinity.
