yes, most are Forcipiger flavissimus but you can get one with a slightly longer snout which is less common, called Forcipiger longirostris. The easiest way to identify them if they only have one species in your LFS is the eye,
The big nose butterfly (Longirostris) has a fully darkened eye. Most you see are the flavissmus variant, well here in the UK you do, most likely because the Longirostris lives in deeper waters.
I like them because they are an unusual shape, very peaceful and mine has been easy in that he ate from day one. I'll get w pic when I get home from work.
Very nice fish and very common. I too this on Bora Bora. I have had them for many years and never had a problem touching corals. I even keep them with copperbands.
Worms and clams is all they need and they can eat plenty of them. I never have a problem getting any fish to eat but I think that is because my system is very natural and I feed natural foods. "Almost" no commercially prepared food.
