My apologies, should have separated my post better.
In very similar predicament. I have a 125gal that's going to be upset shortly. The only sure fish at the moment is the 10"+ Burrfish I currently have (owned 4 years, caught her myself at the beach, the size of a pea). My stocklist changes every day I think. I tried a Lei trigger, that unfortunately harassed, and even bit her a few times. The problem is the Burrfish is quite passive, similar to the dogface. I think at this very moment, I would do a 'puffer oddball' tank. The Burrfish, and maybe something like a Longhorn Cowfish, and a Hawaiian Boxfish, with some smaller fish for activity.
For your tank, what about a Lamarck angelfish and a Harlequin Tuskfish? The angelfish is a planktivore and does not feed on sponge like other angelfish, so it can eat similar foods to the wrasses. The Tusk should get along fine with the red coris. I had my Harlequin Tusk with a Cuban Hogfish in my 125gal, without issue.
