I agree with 3dees.....stick to a pair of clowns vs. multiples - I would generate a list of possible fish you'd like to keep and then determine the best order to add them. Clowns, chromis, gobies, wrasses (need a good cover on the tank for these) and dwarf angels are some hardy fish. Try to stay away from damsels (other than clowns) although they are hardy they can become very aggressive and then hard to catch once established in your tank. Unfortunately, an anemone is not considered an "easy beginner" choice - they need solid water parameters (a more mature tank) and strong lighting. In terms of corals, as others have said, mushrooms, zoas, and other softies can be good beginners.
