Stocking Input for the 150

[Coasting]

I want more fish!!!!

Hopefully the experts here can help me pick out a few....
I would like reef safe in terms of - Doesn't eat coral
I do not keep any type of crabs or shrimp, just snails, theres only 5 snails in the tank right now but I will be grabbing more.
I would really like some bright colours, reds/pinks etc...

I have come to the conclusion that my melanurus is a total dick head. He is the largest fish in the tank, and can be a total jerk at times.
I will have to catch and re-home my butterfly, not because he's eating my coral, because the melanurus is attacking him. He leaves the tangs alone but the poor butterfly....

I need a sturdy fish that wont take any shit from the melanurus. Heck even my anthias who used to rule the tank is scared of him now haha.

I know I run the issue that turd face was in the tank first so he is likely going to go after anyone new. I know the mirror trick, it seems to make him more psychotic. The new tanks glass must be more reflective on the inside or something because hes really chasing his reflection too.

Currently
1 lyretail anthias
1 yellowtail damsel
2 clowns
1 Formosa wrasse
1 melanurus wrasse
1 small sailfin tang
1 small kole tang
1 sailfin blenny
Butterfly to be rehomed if I can catch him. poor dude.

I am thinking of adding another wrasse from the coris genus. (J&L lists a black stripe right now, unsure on its size)
Not sure if I want to risk a fox face with my coral even though the butterfly has been reasonable, more pecking not really eating.
Fairy wrasse are a no go, too delicate lol
its gotta be a bigger fish that can hold its own, no sissys.
Not sure if I want to risk a trigger or.....
Hogfish sound sturdy, but I worry about the "fish eating" prospect that seems to follow their description. And I like my smaller fish.
Perhaps a dottyback at the very last fish?
and obviously look way different then the others. Id love a 4 spot yellow wrasse....

So what are some ideas?
