Unlabeled fish, Australia tanks

The main fish, in the center, is Acanthurus olivaceus
Smaller, white and yellow fish with dark stripes above it > Chaetodon auriga
Smaller bluish fish in the down right corner > Chromis viridis
Fish with only the tail visible in the upper border > Thalassoma lunare

Thank you!

The Acanthurus is really nice - I didn't know about it before
