I have tried both the blue and the Hawaiians. I kept a Hawaiian for over a year, had some trouble with a tank, and had to take it to majestic to house it there for a week or so and it somehow died there with no body no explanation. I was not happy that fish had a cool temperment. The blues are pretty cool too. just make sure you end up getting a true wrasse not a saber tooth blenny. at the store make sure they eat frozen prepared food before taking one home. It has a better chance of survival eating prepared foods instead of relying on eating parasites and dead scales alone. hope this helped.
