me.
I was hoping to get somebody's input on actual behavior experience with

Juvenile specimens are primarily what are seen in the trade, adults are
much
less common. Juveniles are dark overall with alternating white and blue
semicircular bars. This is a great aquarium fish that will thrive in a
well-maintained tank. It will eat a wide variety of aquarium fare,
including
algae growing on the aquarium glass and decor. One of the hardiest of
all
angels for the aquarium! Adults of this species are green overall, with
body
scales that have blue edges. All the fins, except the pectoral fins,
have
blue margins. The dorsal and anal fins of very large adults have
filaments.
At around 5" and larger they begin to take on the blue-green "adult"
color.

Blueface Angelfish
A spectacular Angel, this species can do well if his needs are met.
Making
sure the Blueface Angel is boss of the tank will go a long way in
helping
him adapt. Initially shy, the Blueface can become bold over time, but is
less aggressive than many angels. A spectacular Angel, this species can

Blueface
can become bold over time, but is generally less aggressive than many
angels. The adults of this incredible species have body scales with blue
centers and yellow edges, a yellow dorsal and caudal fin, and a black
spot
at the posterior base of the dorsal. The face is blue, with small yellow
spots. The Blueface Angel should be provided with plenty of swimming
space,
as well as a number of suitable hiding places and kept only with
relatively
peaceful tankmates. The blue-faced angelfish has lived over 21 years in
captivity in one public aquarium.
