IMO this is too wide open. Like saying hey guys I'm buying a 4 bedroom house what should I put in it?
Decide up front: Reef, FOWLR, Aggressive/Passive.
Then decide do you want lots of small active species/corals or 1 large show piece species.
Do you want this to be a grow out tank or a tank for life?
Now you are getting closer.
I've had the following in my 75g FOWLR.
1. Mixed Damsels, Clowns, smaller eels
2. Small Triggers, and groupers
3. And now a DME
Again you need to decide a more limited list based on lighting/filtration equipment you have and what you want.
Hope this helps.
