The clownfish is a type of fish that lives in salt water . It is also called an Anemonefish. Clownfish are typically very bright, orange fish that have three white stripes, one at the head, middle and tail. If you look really closely, you may notice that there are thin black lines around the white stripes. Also, the tips of their fins have a thin black rounded stripe.
Where do Clownfish Live?
Clownfish live at the bottom of the sea in sheltered reefs or in shallow lagoons, usually in pairs. Clownfish have a special relationship with the anemone and are very important to them. They are a large help to the anemone as they clean the anemone by eating the algae and other food leftovers on them. They also protect the sea anemones by chasing away polyp-eating fish, such as the butterfly fish.
What is the Life Cycle of the Clownfish?
The spawning season of the clownfish, a time when they breed, is year round in tropical waters. Males attract the females by courting. Courting behaviours include chasing, biting and extending fins. Clownfish lay their eggs in batches on coral, rock or next to the sea anemone that they call home. The male clownfish will build a nest on the rock or coral near the anemone in order to be provided with protection from predators. Breeding starts by the male chasing the female to the nest where the eggs are released. One hundred to one thousand eggs are laid. The male clownfish guards and protects the eggs until they hatch. They hatch within 4 to 5 days.
What are Some Special Characteristics of the Clownfish?
In a group of clownfish, there is a strict hierarchy of dominance. The largest and most aggressive female is found at the top. Only two clownfish, a male and a female, in a group reproduce through external fertilization. The clownfish are hermaphrodites, meaning that they develop into males first, and when they mature, they become females. Also, as mentioned earlier, more than one clownfish is able to live in a sea anemone. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males would become a female. The rest of the remaining males will move up a rank on the hierarchy.
