135 gallon

[Mmun]

I have a 135 gallon tank. It is home to a Tusk Fish, Tomato Clownfish, Blue Jaw Trigger, Green Bird Wrasse and Cuban Hogfish. I have live rock and live sand. Sump, Skimmer, etc.
My question, is what would be a cool fish to add to this mix? The Tusk fish and Clownfish can be kind of aggressive. I am thinking something in the 6" to 8" range full grown. Would another wrasse work?
If so, what would you recommend wrasse or not?
Thanks

How about a cool Harlequin Bass— 11 1/2” (Max), semi-agressive (to hold his own).

If I went with a smaller triggerfish, which one would you choose? Niger, Picasso, Red Tail, or Pink Tail. I would love a crosshatch but I don't know if I can swallow 700 for a fish.

I think Pink Tail Triggers are very cool.
