I hope this is your starting list, because it's a pretty big list for a 60 gallon tank. If it isn't...
...adding additional tangs and foxface can be an issue since the current have claimed their territory... the tank. If you insist on adding more, do it early so the fighting doesn't freak out the other newcomers. Clowns, goby, blenny, and firefish are passive, so they can be added early, then basslet.. Damsel and wrasse, same class as dottybacks, can be aggressive... added last. If you find a tank bred, or tank raised Dragonet, make sure it's eating frozen processed food before purchasing. Otherwise, wait a minimum of 6 months after seeding your tank with pods, and a refugium is a huge plus in this case.
Dottybacks,can be aggressive, especially to newcomers. Reef safe, one per tank, added last.
