Male squareback anthias can get to 6" and would certainly be reef safe. Even if you got one that never attained max length, the shape makes it a nice size fish and an attention grabber.
I had one years ago that I bought mealy full grown about 4.5" and he died for unknown reasons (he could have just been old) I have always wanted another, I t just hanged crossed my mind yet, Thank you for reminding me![emoji1]
