Looking to start new saltwater aquarium

[Clifton Barton]

I'm soon to start a new 55 gallon saltwater aquarium. I need all the tips I can get. I want a very diverse tank with as many different coexisting fish as possible as well as invertebrates like shrimp, hermit crab and any good suggestions. I need a list of diverse 2-3 inch fish (can be smaller if not not eaten by bigger fish). Basically I need a very busy multi species tank that involves invertebrates. Any advice is appreciated.
