Found this fish in Dominica, 35 feet, night dive, on sandy bottom. Unafraid upon close approach.
Looks like a member of Serranidae... Hope someone else can chime in on which specie.
Check your references for the dwarf sand perch and see if that's a match.
Let me see if I can find a photo to confirm.
Could be, but inconclusive by this photo http://fishbase.cn/summary/Diplectrum-bivittatum.html
I checked your photo against the Kells & Carpenter book, and DiverDave's identification as a Dwarf Sand Perch is right on. Very nice photo and a good ID in my opinion.
