Red velvet can be aggressive. I rate mine right up with my Pyles for aggression. The Flame wrasse is pricey but they are really showy. IMO they are not the strong swimmers many of the other wrasse are so they tend to just hang out more and look cool. You could also check out the Orange back wrasse. Very cool color, not too big, reasonably priced and yet not extremely common. The problem is there are so many choices. Just make sure your tank is covered if you plan to add any wrasse, they are jumpers.
