ANYONE KNOWS THIS FISH?

I saw this guy ( the one in the middle of the pic ) in about 35' on the southeast of Dominican Republic .

Two of them were swimming among a group of glass gobies . They keep moving all the time and don't allow to get close enough for a good pic.

I'll appreciate any help .
