Best known for being feature in the movies “ Finding Nemo ” and “ Finding Dory , ” the clownfish has become a popular aquarium pet . Nemo and his dad , Marlin , are ocellaris clownfish , also called assumed clownfish or clown anemonefish . Anemonefish are so - diagnose for the sea anemones in which they make their home . There are 28 species of anemonefish , and they come in many colors , such as pinkish , red , yellow , black , brown and multi - coloured grade insignia .
Size & description
Most imitation clownfish are orangewith three white bands on the head and body . The white dance band are outline in blackened . Their bodies are a bite more than 3 inches ( 88 millimeter ) long on average , but they may develop up to 4 inches ( 110 mm ) , concord to the Animal Diversity World Wide Web ( ADW ) . The derriere is rounded and the dorsal fin is lined with 11 prickle .
Habitat
False clownfish go in the coral reef off the coasts of Australia and Southeast Asia as far north as southern Japan . They are found primarily around sure form of windflower , a creature that drop anchor itself to the ocean flooring and uses its tentacles to attract food . The anemone ’s tentacles have stinging jail cell forebode nematocysts that release a toxin when prey or predator touches it .
Clownfish , however , acquire resistance to the toxinby very cautiously touch the tentacle with different parts of their body , according to National Geographic . A stratum of mucus builds up , protecting the clownfish from the toxin . The pair forms a symbiotic relationship . The anemone provides protection and leftovers for the clownfish , while the clownfish get intellectual nourishment to the sea anemone and preens its host , removing parasites .
Habits
All anemonefish , including clownfish , are hermaphrodites . They are all born male person , consort to National Geographic . They have the power to turn over themselves female , but once the modification is made , they ca n’t go back to being male . Sometimes the change is made when mating . Two males will become mates and the larger , dominant fish will become the female .
These social Pisces live in groups that are led by one dominant female person , according to the ADW . The second expectant fish is the dominant male person while all of the other fish in the group are smaller males . If the distaff dice , the prevalent male will become a female person to supercede her . The largest of the smaller male person will then become the dominant male person of the group .
Clownfish communicate by making pop and clicking noise , according to a study on the daybook PLOS One . Researchers say thechatter helps maintain the rank and fileamong mathematical group member . " speech sound could be an interesting scheme for forestall dispute between grouping member , " lead study author Orphal Colleye , a postdoctoral fellow at the University of Liège , Belgium , told LiveScience in a 2012 article .
Clownfish make their homes near sea anemones, which protect them from predators.
Diet
Clownfish are omnivore , which intend they eat meat and plants . They typically eat algae , zooplankton , worm and small crustaceans , accord to theNational Aquarium .
When modest , the Pisces tend to stay within the confines of their windflower host . As they get larger , they will seek out food for thought , though they do n’t venture much more than a few m from the anemone , according to the ADW .
Mating & offspring
picayune is known specifically about assumed clownfish conjugation behaviors , but the general behaviors of anemonefish are have it off . All anemonefish are monogamous . Before spawning , the male person prepares a nest by clearing a stain on bare rock near the anemone , agree to the ADW . He then courts a distaff witha show of drawn-out fins , mordacious and chasing , according to the Florida Museum of Natural History . He chase the female person to the nest , but after that it is up to her to make the next move .
She will make several notch over the nest before depositing her egg . She will lie from 100 to 1,000 eggs , which are 3 to 4 millimeter long . The male then slide by over the nest and turn sperm to inseminate the eggs . Then , the female swims off .
The male does most of the " egg session . " He will fan them and run through any ballock that are infertile or damaged by fungus , according to the ADW . The nut hatch six to eight days later . The larvae float away and spend about 10 day rudderless . They start their life readable or limpid , but as they commence to grow they start up to gain the colouring of their species . As juveniles , the new will go under to the bottom of the reef to search for a host anemone .

Conservation status
Ocellaris clownfish are not peril . However , in the last generation , 15 to 30 per centum of the reality ’s reefs have been suffer , harmonize to the ADW . Some of the destruction has been have by fisherman catching clownfish to betray as pets .
According to National Geographic , since “ Finding Nemo ” premiered clownfish sales have tripled . Conservationists are concerned about the " Nemo Effect , " as some areas are overfished to meet the requirement for these popular aquarium Pisces . Also , according to theAquarium Welfare Association(AWA ) , many hoi polloi bought the clownfish without know how to decently worry for them . barrack by a line in the movie , hundreds of children blush their clownfish down the toilette in the Bob Hope of setting them free .
