weird colorful fish

[polarpooch]

This was called a 'rooster wrasse' at the LFS. It changes color from orange/yellow to red/purple to red/orange/purple to red/white.
Supposedly it's from Tonga.
Looks like some kind of hogfish or maori wrasse? Could it be a sneaky or cryptic wrasse?
Anyone know the latin name so I can look it up?

Kinda looks like the fire hawk fish my buddy picked up today.

Thanks Tyr, but I'm sure it's not a hawk fish. Though I do see some resemblance.
The LFS had no information, save telling me it's maximum size was about 6" and that it was a wrasse. It looks like a type of Sneaky Wrasse. It changes color dramatically when it's spooked.
