What to add next...?

[W1ngz]

I'm considering these:
Flame hawkfish. Adorable, personable, with a good flash of colour. But, I also read they will definitely kill off and eat shrimp. I really like my shrimp and want to add/replace my lost cleaner shimp and a pair of peppermints. Are flame hawks really that bad?

A fairy wrasse, maybe a bluehead or Exquisite. Only possible concern is my sixline, but he's an angel, I've never seen it pick on anyone new or old.

An Anthias of some form or other.

90 Gallon cube mature mixed reef, recently moved over from a standard 75 gallon.

Current occupants:
Assorted hermits and snails
Coral banded and fire shrimp
Brittle sea star
Wheeler's goby and tiger pistol
Pair of black ocellaris
sixline
PJ cardinal
black cap basslet
onespot foxface
Firefish
There will eventually be a mandarin or red scooter blenny in there also, in a few months.

Sixline and Mandarin together is a no-no. In my 420 gal DT, my Sixline pair kill my mandarin female by coordinated attack. One of each side and pecked her eyes out within a few second of each other. Once the dirty deed was done, they completely ignored her and go on their merry way pecking at the pods on the rock. They did not go after the male Mandarin.
A few hrs later, they were captured and went to the LFS. A week later I euthanized the female Mandarin.
That was pure evil, premeditated murder with extreme prejudice. All 4 fishes were in my 420 gal for at least 2 years. All are fat and spawning regularly.

I would go with a fairy wrasse. Super active and stick to themselves for the most part. Flame hawk close second.
