Hi ChiliDog,
Start slow and stock you tank one animal at a time. It's good that you're planning though.
First, I reccomend a single "centerpiece fish" and build your list around it. The Centerpiece will probably not be your first fish, but your fist fish need to be compatible with your Centerpiece
IMO A Flame Angel or Kole Tang would be a great Centerpiece for you but it's up to your preferences.
A 90 gallon reef won't support as many fish as you'd think but you can have an amazing display if you pick the right ones.
The number of corals you can have is almost limitless but there can be compatibility problems so, again, pick a centerpiece "Must Have" and build from there.
