This butterfly fish also has a wide range from the Indo-Pacific through to
the Central Pacific, but it is not numerous anywhere. It is also known as the Saddled
Butterfly fish. It is certainly not among the easiest butterfly fishes to keep with regard
to starting it feeding in the aquarium. However, like the Copper Band, once feeding has
begun in earnest, the Black-wedge Butterfly fish proves to be one of the most
indestructible of all sea aquarium occupants.
Unlike C. auriga, C. lunula and C. kleini, this butterfly fish is seldom obtainable in
small sizes. Most specimens seen offered for sale are young adults around 3 to 4in (7 to
10cm) body length. This may well account for the difficulties often experienced in getting
the Black-wedge to feed in captivity. It is not unlikely that an adult fish would have
already formed very definite feeding habits and preferences for certain items of diet not
available in the sea aquarium. Modifying such establishes habits might prove more
difficult for an older fish than for a relatively young one.
