The Clownfish, Amphiprion bicinctus, is an uncommon oceanic fish that can be caught all day between the months of April and September. It sells for 650 Bells.
An information board in the aquarium will provide information about this fish.
"Clown fish spend their lives hiding among the feelers of sea anemones, a place that only they can live. Their homes may be dangerous, but they produce a special coating that protects them from the poison. In exchange for the anemone's protection, the clown fish chases off any parasitic bugs and enemies. Curiously, all clown fish are males when they're young but change into females if necessity demands."
In real life
The Red Sea Clownfish (or Two-banded Anemonefish) can be found in the Western Indian Ocean, the Red Sea, and the Chagos archipelago. They inhabit lagoons and outer reefs and live symbiotically with anemones. The tentacles of the anemone protect the clownfish from predators. The anemone benefits by the clownfish’s movement among its tentacles, which increases water flow and therefore oxygen. Clownfish will feed on benthic (bottom-dwelling) algae and occasionally on zooplankton.
Clownfish can change from male into female. They begin their lives as males, but when a female dies the dominant male will change into a female. A non-dominant male will then become the dominant male.
