This fish lives in open water, on the surface or often in deep lagoons or near steep slopes.
He lives on a shoal and has diurnal activity. We can see in these shoals its close parent (Caesio teres), to distinguish them we must look at the yellow part which is different in the Teres according to the age and which starts from the caudal diagonally.
Some sharks can stay motionless on the sand (white tips reef sharks, nurse sharks, etc.).
These sharks don't have to swim to bring oxygen to their gills like other sharks (grey, hammerheads tc.)
Parrotfish create a protective envelope around them when they are sleeping.
So, don't put the light on them during night dive to don't to wake them up and break this envelope.
The whale shark is the largest fish in the world!
Some whales are larger, but they are mammals, not fish!
