The most popular reason to get a fish tattoo would be because you are of the astrological sign Pisces, or born in between February and March twentieth. The symbol of Pisces is a fish, and to identify themselves as such, a person might get tattoo of a fish.
Also, tattoos of koi fish are increasingly popular among the young, hip demographic. Koi are Japanese fish and getting them as a part of "sleeves" - or tattoos that cover the entire arm - was popularized during the surge in the popularity of Japanese artists. Koi are also easily translated into tattoo form, looking superb when tattooed realistically or cartoon-style. Koi are found in nature in many stunning colors, which is another reason their for their popularity in art and body art.
Another popular fish to adorn your skin with is the beta fish. These fish are notoriously aggressive, held up as fighters. Those who identify as one with a fighting spirit may want to get a beta fish tattooed. These fish have beautiful colors and fan-like fins, adding to their tattoo popularity. A realistic beta fish tattooed by a skilled artist would be stunning.
Also, tattoos of sharks can be done beautifully. Whether someone chooses to get a tattoo of a shark as some sort of symbolism or because they are fans of them, shark tattoos are uncommon, though striking.
The beta, the shark, and the next popular fish, the piranha, all identify the wearer of such a tattoo as either a fan of the fish or someone who is expressing their fighting heart with such symbolically "fighter" fish. Tattoos of the Amazon's carnivorous piranha are popular and beautiful.
Of course, the Christian fish is also very prevalent. People of Christian faith may want to display their devotion to their beliefs with the one-lined, clean, simple tattoo associated with Christianity.
Whatever your reason for perusing fish tattoo design, it's important to know exactly what you want, choose a great artist, a perfect design, and your preferred place for the new ink. It's important to choose the pose, color, and style of your preferred fish and take the time to communicate with your chosen tattoo artist about what you want. Good luck with your fish tattoo!
