Well, no triggers do great in reef tanks, but of them, Pink-tails and Blue Jaws do pretty well.
Pros of blue jaws: little less aggressive, smaller
Pros of pinktails: cheaper, aren't as 'destructive' in that they don't move lr around or in your case coral
So the choice is really yours. If you have the money, go for a Blue jaw. If you have the space, go for a Pink Tail.
