Koi fish tattoos represent good fortune and luck. However, different cultures pull different meanings from the Japanese carp, depending on various factors such as color.
Koi fish represent good luck because it was believed in ancient Asian legends that the fish could swim up rivers and become dragons of gold. The color gold is often associated with wealth and good luck. Koi also often symbolize personal strength and perseverance. They represent a person's desire to better themselves or to find their fortune. Those with high expectations in their daily lives often get Koi tattoos as a reminder to never settle for less.
