Beach Bum,
I have seen it, very cool looking. Does not have the black strips across the back like the one in your picture. LFS said, and looked up in Atlas, that this an adult coloring and will maintain it. Currently is about 5" they said the one that is 18" was sold about 5 years ago, and was about 6" when sold.
I was planing on haveing a pair of blue throats (chins) which are mellow for triggers. Have built six diffined seperate caves in my 180 hoping to give 4-5 fish there own territory.
