Which is the better reef safe fish?

Purple tang, same size as a yellow and love the colors.

As mentioned before, marine betta. He's my favorite fish in the tank, super chill. Mine always comes up to the glass, he knows he's stunning and says 'look at me' in an Italian accent.
Some can be shy from why i've read though. Mine didnt bother my cleaners nor fire shrimp however he stays up late and when i dropped in a harlequin after midnight, he had a snack.

Kole tang has my vote. Lots of personality and a great algae eater.
