the clownfish

A clownfish refers to a group of 30 coral reef marine fishes of the subfamily Amphiprioninae in the family Pomacentridae. The clownfish are all orange, yellow or brown, often with broad white bands and any species of clownfish necessarily lives in symbiosis with a sea anemone, a sea anemone. In taxonomy, the names of the two Clownfish-related genera are Amphiprion (29 species) and the monospecific Premnas genus (1 species). The largest clownfish can reach a length of 18 centimeters, while the smallest species can hardly reach 7 centimeters.

Physical description
Clown fish belong to the family Pomacentridae. In the adult state, their size varies from 6 to 16 cm and they weigh about 50 g. Their color varies depending on the species but overall they are orange (which varies from yellow-orange to dark orange or pink) and black. Some species have vertical bands or a white dorsal band, others do not.

it's place of life
In the wild, clownfish are generally found in all seas and oceans and in the tropics. These fish live very often in the reefs in the middle of the sea anemones. These anemones constitute for this small fish a refuge where it shelters to escape its predators.

it's diet
The clownfish is a carnivorous fish that feeds on small prey found mainly in plankton, usually consisting of small crustaceans called copepods, larvae and algae.

reproduction
Depending on the area, the clownfish may have a varying breeding season. It can spread throughout the year in tropical zones, in spring and summer in subtropical or temperate zones. The laying is preceded by a whole ritual during which the social behavior of the clown fish is marked by chases, erection of the fins and preparation of the nests. The male becomes more aggressive towards his partner and exhibits his swimmer skills to attract the female.

It is the male who chooses a nest for the larvae in a rock close to the anemones that he takes the trouble to rid of all the undesirable elements. He is also the one who watches over the nest during the incubation week by ventilating the eggs and chasing the egg eaters. The time of laying, the female swims zigzagging and rubbing the abdomen on the rock chosen by the male. The latter follows the female by fertilizing the eggs left behind her. The laying can last between 30 minutes and 2 hours of time, the quantity of eggs ranging from 600 to 1600 eggs. The hatching takes place a week later and after ten days, the larva becomes a young fish.

His life expectancy
In the wild, the life expectancy of clownfish is poorly known; but some people agree that it is between 6 and 10 years old. In aquariums, clownfish can live up to 18 years.

The cry of the clown fish
Clown fish communicate through a variety of sounds. These sounds, depending on the number of pulses, the duration and the dominant frequency can be a sign of submission or aggression. Males produce some kind of grunting when the female enters her nest.

Particular signs
The clownfish lives in perfect harmony with the sea anemone whose venom is deadly for other fish. However, without knowing how, or why, he would be immune to his venom.
