Need advice on last fish

[Ardee]

I currently have the following, and I am wanting 1 more.

Panther Grouper
Blue Jaw Trigger
Pinktail Trigger
Harlequin Tusk
Dogface Puffer
Vlamingi Tang

It is, of course, a FOWLR

Thanks for any advice

What size tank: How about an angel, I've got 4 of the same fish. I have a majestic, cool fish; adult colors at a small size, laid back doesn't grow that fast.

Tank size definitely matters. Maybe a zebra eel.

It is a 180

+1 to the Zebra Eel, you could also consider a chainlink, or snowflake.
