The super bright orange skirted one with the grey center is The Destroyer Paly from Ultimatefrags. It is easily one of my favorites. It is Dayglo fluorescent orange in person, just looks orange in the top down pic unfortunately.
not sure what type it is. i got it from the LFS months ago. it used to be almost buried in the sand in one of their tanks. then one day when i went it was against the glass. i noticed the pink and asked about it. he didnt know what type it was. i paid 5 bucks for it. it has grown and colored up alot since i got it. i feed it mysis at least once a week. it hasnt moved since i put it where it is today. i like it alot also. thanks for the comment.
