Here's a fish with a big tear in one of his fins…and he's swimming along just fine. Alternate wriggling your fins and your tail. You got yourself in there, you can get yourself out. GILL: Nobody touch him! Nobody touch him. He needs dear old dad around to protect him at all times.īut Nemo realizes this isn't quite true when he meets the take-no-prisoners Gill: We call it his lucky fin.Īll his life, Nemo's dad has told him that he's not capable of the same things as other fish because of his lucky fin. PEARL: What's wrong with his fin? TAD: He looks funny! SHELDON: Ow! Hey, what'd I do? What'd I do? BOB: Be nice. He hurt it while he was still an egg during the barracuda attack that claimed the lives of his mom and sister. Nemo's right fin is his "lucky" fun, which means that it's a little smaller than the typically sized fin on his left. The clownfish will see our hand as a threat and attack it.Swimming around in the ocean is a dangerous business (or so Marlin likes to remind us), that's why it's no surprise that we've got some characters with damaged fins hanging around in this movie. We as aquarists have to be mindful not to get out hands too close to their anemone when our hands are in the tank cleaning it. They’re very territorial and if introduced to new clownfish they will fight and won’t let them into the safe haven of the anemone. Though the clownfish look pretty cute, they’re actually one of the most aggressive fish we keep in the aquarium. So, when Coral died in the film, Marlin would change to Nemo’s mother! If the female dies, the mating male changes sex to female and the largest of the group of males will become the breeding partner. In the wild there will be a breeding pair, male and females, and also 0-4 other smaller males in their group. Butterfly fish are known to eat anemones, the clownfish will bump and bash into any hungry butterflies and warn them off, the clownfish faeces also supplies the anemone with sustenance.Ĭlownfish are protoneous hermaphrodites, this means that all clownfish are born male and the biggest will change into a female. The anemone also benefits from the presence of a clownfish. Anemones also provide food to the clownfish, they will pick at the fish the anemone has caught and also pick off any dying tentacles. The anemones provide protection to the clownfish, as clownfish are clumsy swimmers, they don’t venture too far from their host anemone, if they were to a swift predator like a shark would snap them up right away. Once at full immunity the clownfish can pop right into the anemone and stay there. When a clownfish is introduced to a new anemone they don’t just dive straight in, they shimmy up to the anemone, letting the tentacles touch parts of their body, and shimmy away, then shimmy back up. One well regarded theory is that clownfish build up an immunity to the sting. They don’t sting the clownfish - no solid reason has been found as to why this is - but there are a few theories. Anemones are venomous, they use the stings on their tentacles, to paralyse and hold on to other fish for food. Our clownfish live in Magnificent Sea Anemones, but they can also inhabit other types. Clownfish have a mutual beneficial relationship with sea anemones. They’re found in coral lagoons and reefs flats, and inhabit The Great Barrier Reef. Percula clownfish are found in the Western pacific - Queensland and Melanesia. There are 30 different species of clownfish, we keep three different kinds including the percula. The clownfish featured in 'Finding Nemo' are Percula clownfish or 'Amphiprion percula'. Children and adults a like will point with glee and exclaim “NEMO!” It’s no surprise given the massive success of the film and the iconic look the clownfish has. It’s safe to say our clownfish are one of the most popular fish in our aquarium, and often draw the most attention. I'm going to start with the characters Nemo, Marlin and Coral, who are all clownfish. I'll be picking out the characters from the film 'Finding Nemo' and telling you more about the real fish behind the animation! Over the next few months I'm going to introduce you to some of the fish in our Aquarium. Hi, I'm Alyster and I'm an aquarist at the Aquarium at World Museum.
