Looking to purchase new Fish

I'm a running a 75 gallon tank with a yellow tang, blue damsal, flame angel, clown, and bengai cardinal.

I'd like to add a fish that is an active swimmer which will get along with the other fish in the tank. Tank has coral so would need to be reef safe.

Any suggestions?

 

6 line wrasse?

 

Thanks. Do I need to have a closed top tank for them? I forgot to mention I have an open top tank.

 

Build a screen top

 

The sixline wrasse is what I would recommend. And you should have a screen top not only for them, but almost all fish have the potential to jump. Check out this sticky for info:
