claimed to have taken the fish from the nearby shore. Juveniles sometimes seen on some of our shores. They are commonly seen around caves, wrecks or jetties, and often
in murky water.
Features: To about 30cm. Golden
brown to orange body with diagonal blue lines on the sides and a blue
ring behind the eye. The tail fin is white with bright yellow margin.
Juveniles are bluish-black with a series of white and blue narrow
bars on the sides. Juveniles found in shallow areas with short filamentous
algae growing on rocks or dead corals. Adults often found in pairs.

What does it eat? It eats sponges,
ascidians and zooplankton.
Human Uses: This fish is unfortunately
harvested from the wild for the live aquarium trade.
Status and threats: Although the
fish is not listed among the threatened animals of Singapore, like
other creatures of the intertidal zone, they are affected by human
activities such as reclamation and pollution. Over collection by hobbyists
and overfishing can also have an impact on local populations. |

Thanks
to Jeffrey Low for identifying the juvenile anglefish. Thanks also
to Anthony Gill who suggests this fish might instead be the juvenile
of a Pomacanthus species - most likely P. annularis.
