The adult of this species is considerably smaller at 12 to 15 in (30 to 38
cm) than the Black Angelfish at 18 to 22 in (45 to 55 cm). As previously stated, the
vertical barring on the juvenile is a daffodil yellow colour, making it a much more
attractive fish. It is also considerably more attractive as an adult, characterised by a
charcoal grey to blackish body colour with the posterior margin of each scale having a
creamy white to pale yellow edge. If anything, the French Angelfish is a little more fussy
than the Black Angelfish with regard to feeding, although both species do well once
settled into a suitably designed habitat. Adequate cover must be provided.
One cannot overstress the need for complete peace and quiet for a fish newly introduced
into a sea aquarium. All too often, I am the recipient of agitated telephone calls from
beginners asking why, despite the fact that they have offered ten different foods in the
space of as many minutes, their newly purchased butterfly fish or angelfish is still
cowering behind a rock. Nothing can be relied on more to send a nervous coral fish into a
state of deep shock than this sort of behaviour.
