This is a True Clown Fish in a purple tipped Anemone - Most people call all
Anemone fish, Clown fish, but they are not! The fish has to look like the one
in the picture to own the name. 
This photo was taken on a second dive at the same site in Papua New Guinea
from a live aboard dive boat
As Murphy would have it, I usually see something fantastic after I shot my
36th frame with 300psi (next to nothing) of air left.
On a live aboard that caters to photographers, you  can usually request to
do the site again.
Most regular people, divers or photographers will never realize how difficult
underwater photography is until you hand them a housed camera and lights
underwater! Especially when you are dealing with Shy  Fish, moving currents,
buoyancy (as in not being able to hold on to  or touch anything), other divers
that are breathing  (creating bubbles) wanting to see what you are shooting,
and heavy equipment that is even heavy underwater.
The one thing that makes underwater photography so appealing to me is you
don't always see the true color of what you are shooting under the water. At
60 feet you lose all reds, pinks and most other colors. It takes a light
source to bring them out, so when the photos are shot with a flash and then
developed, there are always surprises!  This is not an enhanced photo! What
you see is what I shot, and actually I didn't even see it this brightly since
it was so deep. I  am bringing it up from the deep for everyone to enjoy.
