The Double Saddleback
Butterfly (C. ulietensis)
The double saddleback butterfly (C.
ulietensis) is found in the tropical Eastern
Indian Ocean and primarily in the Western
and Central Pacific Ocean, from Japan to
the Cocos-Keeling Islands and Tuamotu
Islands. It is relatively small, with a
maximum reported length of just under 6
inches ( 15 cm), and typically lives in reef
lagoons, with some being found on seaward
reefs. It is sometimes found alone, but they
may also live in mated pairs or in small
groups. It feeds on corals, anemones, other
invertebrates, and algae.
In the aquarium, this species is typically
very peaceful, and several can be kept
together whether they are part of a mated
pair or not. This fish even gets along with
Double saddleback butterfly (C. ulietensis).
The collare butterfly (C. collare) can be kept with a few others of its
species in a large enough tank.
