Tankmates for my Miniatus

[Mistborn]

Hi guys right now I have a 120~ gallon tank with a snowflake eel, a Miniatus Grouper, and a Foxface. I wanted to add something else in there since the tank is pretty empty with just three critters, two of which spend most of the time in or around rocks. Any suggestions?

Laterally compressed fish, such as tangs, butterflies, or monos. Possibly picasso trigger or a pufferfish.

Well I came home from Miami, and a surprise in my tank. A Pink-tailed Triggerfish as a birthday gift. My dad said the lfs said it would be okay. I've been watching the tank for a while and while I noticed the trigger has some very minor scratches from the miniatus, he doesn't seem to be attacking it. Even when the trigger gets right in front of his cave, the miniatus just opens his mouth and doesn't strike. Hopefully this works out. The trigger is really nice.
