Where
seen? This small pretty fish is sometimes
seen on our Southern shores, near living reefs. It's fast-moving so
it's sometimes difficult to spot. Elsewhere, they are found in shallow
sheltered waters in mangroves, reefs as well as near man-made structures.
Features: To
over 11cm, those seen usually about 6cm. Body rounded with fins that are all rounded, including the tail fins. Dark
brown bar across the middle from the start of the spiny
dorsal fin to just in front of the anus. Dark round spots on
the back half of the body. Pectoral fins colourfully marked in a yellow-brown pattern. Seen alone or in small groups. |

Cardinal babies: As with
many other cardinalfishes, the male incubates the eggs. According
to FishBase,
he does this for 8 days.
What
does it eat? According to FishBase,
it feeds mainly on planktonic crustaceans, feeding at night in the
evening and just before daybreak. Although there was one observation of one Orbicular cardinalfish "snapping up Tropical silversides using its tongue and rapidly swallowing the prey whole (like a frog eating a fly)."
Human uses: It is popular in the
live aquarium trade. |
*Species are difficult to positively identify without close examination.
