Fish ID

I think the larger one is a humphead wrasse.
The smaller one is a triggerfish of some sort.

@German Zoo World This was more to find what is behind it, bicolour Chromis but more importantly the species of butterflyfish in the distance.

This is taken from Flickr, right?

@amur leopard It’s my mother’s photo, I was only 3 at the time.

The big fellow is also called a Napoleon wrasse.

Besides the already mentioned species plus the only half-identified triggerfish that is Odonus niger, I can only see an Acanthurus olivaceus. I fail to see any butterflyfish in this pic.

I see a fish that might be Vagabond Butterflyfish but I'm not confident in that since it's too far into the background.

Paracanthurus hepatus is also visible in the background

@Kakapo the trigger is Melichthys vidua
