Where
seen? This
black anemonefish with white spots is sometimes seen on our submerged
reefs, living in a Giant
carpet anemone, often sharing the anemone with Peacock anemoneshrimps. Elsewhere, juveniles are often seen living in large sea anemones, sea urchins, or branching corals.
Adults found in pairs or small groups around coral mounds or rocks.
Features: To 11cm. Juveniles are
jet black with white blotch on forehead and on the sides near the
upperside of the body. As they age, the spots fade. Adults are greyish
with variable 'spottiness', some with no spot on forehead; or very
reduced side spot.

What does it eat? It feeds on
algae, copepods, and other planktonic crustaceans.
Human uses: Unfortunately, these
fishes are taken from the wild for the aquarium trade. The harvest
may involve the use of cyanide or blasting, which damage the habitat
and kill many other creatures. Like other fish and creatures harvested
from the wild, most die before they can reach the retailers. Without
professional care, most die soon after they are sold. Often of starvation
as owners are unable to provide the small creatures and plants that
these fishes need to survive. In artificial conditions, many succumb
to diseases and poor health. Those that do survive are unlikely to
breed. |
