Identification please - purple/yellow butterfly?

[derek.reef]

West coast of Palawan island in the Philippines -- we spotted 3 pairs (always 2 together) of these fish, in 3 different locations (unless it was the same pair swimming about 100-150 miles a day). As far as i can tell seemed to butterflies.

Can anybody name these?

i can email videos too! (which are not better quality)

I have not been able to upload the pictures here directly, and i unfortunately have a very bad internet connection that doesn't give me much ability to play around until i get it. SORRY!

Thank you!

Chaetodon lunulatus. Beautiful, but practically impossible to keep in an aquarium due to their strict diet of live coral polyps.

Wonderful diving there. I recall that area fondly.
