I got this little guy at my local LFS. I had to bring back a bonded pair of blue throat triggers because they started eating the smaller fish, even though they were both 3" or under. So after watching this guy for awhile, I decided to give him a try. It's a juvenille of some tile fish? species they said and had it labeled as a Blue Bellquio (Sp). However, I cannot find one single thing about it anywhere online. They have a biologist that works there and he also has one and told me what he knew about it. For the record it is not a cleaner wrasse, neon goby or any type of eel goby.
