CHAETODONTIDAE (BUTTERFLYFISHES)
Butterflyfishes
are among the most conspicuous and colorful of all reef fishes.
Most scientists agree that their color patterns play an important
role in aiding them in recognizing members of their own species
for reproduction and territorial defense. Some believe their
colors serve to advertize the fact to would-be predators that they
are bony and not worth the trouble to eat, yet there are many predators
that readily eat them. Most butterflyfishes are carnivores;
a few are omnivores. Some of the carnivores feed primarily
on soft corals, small benthic invertebrates, or even on zooplankton.
Most occur singly or in pairs and are diurnally active, home-ranging
fishes. By day, they patrol a specific portion of reef in
search of food, and at night they sleep hidden among corals or rocks,
often exhibiting a color pattern somewhat different from that of
the day. A few of the coral polyp feeders are territorial,
remaining in the vicinity of a home coral head. The zooplankton
feeders form large aggregations that may extend several meters above
the reef. Butterflyfishes spawn in the water column, producing
tiny, buoyant eggs that are dispersed by the currents. All
but one of the 29 species known from Guam occur at depths accessible
to scuba divers.
