[coral reefer]

You may want to add other types of coral to your tanks diversity. Unfortunately, your fish population is pretty much topped out, in my opinion. Also, Domino's, Clown fish and Tangs can be very aggressive, especially with the introduction of new species.
Also, maybe other species of invertebrates may be just what you are looking for.
Long Tentacle Anemones are not that appropriate for a reef tank! I know you weren't looking forward to hearing that, however, anemones can and will sting and possibly kill other corals as well as fish if they can catch them.
Cleaner shrimp, Conch, hermits(Blue legs and scarlet reefs) just to name a few.
Now consider Gorgonians, Tunicates(Sea Squirts), Sponges(Porifera), some of the more hardy species of Small stony corals, such as Montipora, Pavona, porites and Millipora Acropora. Large polyped stonies like Brain and Plate corals will also be a welcome addition to a reef tank that you are so eagerly looking to replicate.
You should read about each species of coral regarding husbandry, compatibility, and how hardy the particular species of coral etc. is.
Ideal water parameters and proper equipment is also essential in you efforts and success in creating a diverse and beautiful reef biotope, over and above that which you currently possess.
This is it in a nut shell without taking too much of your time and rambling on at this particular time.
Best of luck and hope this helps!
