a species of marine reef-fish, of which
juveniles look nothing like their adults, and
also live separately from them.
Juveniles are dark blue to black, with a pattern
of white, vivid blue and yellow lines, that form
toward the centre rear of the body and become
circular spots on the dorsal and anal fins.
Emperor Angelfish are
popular aquarium fish, though this may
obstruct transition into full
adult colouration. See also
