(You can read a cool movie review about the above title)
Nemo and his father, Marlin, are ocellaris clownfish, also called false clownfish or clown anemonefish. Anemonefish are so-named for the ocean anemones wherein they make their homes.
Technically on this realistic color tattoo, you can see a real clownfish. Not the 3d rendered one, but it’s so similar to the movie version we can call him Nemo too.
