As Koi fish can make a beautiful tattoo with lots of bright color and large splashes of blue water that can become a very flowing and artistic tattoo, most women tend to get koi fish tattoos on arms, thighs, and even on the side of their stomachs. Men tend to get koi fish tattoos on their back, shoulders, calf or upper thigh. The large koi fish tattoos need to take up the entire back. It is another reason why many men are starting to get such fish. They can also make a great full sleeve design with the water and koi fish twisting around the arm or leg.
