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.)
Mammals have a horizontal tail.
Fishes have a vertical fin.
Turtles are in economy mode when they are sleeping. If they are woken during night, they may not have enough air to return to surface.
So, please be careful during night dives!
