Popular amongst aquarists and
extremely robust compared with the juveniles
of some species of angelfish the Emperor is
readily identified by the circular white hoops
present in the pigment on the latter half of
the body. These can be more or less irregular
but usually complete.
Emperors grow quickly given good
conditions. They appreciate a varied died including
green foodstuffs. Juvenile Emperors will often
clean parasites from other fish in the reef
and will occasionally do this in the home aquarium.
Thus they are seldom hassled by their tankmates;
indeed they seem to be blissfully unaware of
how small and insignificant they appear, sometimes
chasing fish 2-3 times their size.
