2 volitans lion fish
Warty frogfish (or any frogfish really)
picasso triggerfish
Queen or Blue Angelfish
Coral hind
Thanks loadssss

I am definitely not marine expert but stay away from the frog (Angler Fish).
I once had a 6 inch frog fully consume a 7 inch Majestic Angel!
This was particularly saddening since the Majestic cost me $300.
In any aggressive tank try to look at their mouth sizes. Make sure they are generally the same.
