Critter ID - Seen in Indonesia

Can anyone identify this critter? I saw it on a dive in Indonesia. I had originally thought it was a Flamboyant Cuttlefish, but looking at the image more closely makes me think it is clearly not a flamboyant cuttllefish. So the question is, what is it?

Many thanks for your help.

Thank you both for the critter ID!

Your input was much appreciated.

Also commonly called a Peacock Mantis Shrimp (in this part of the world at least)
