What does a koi dragon tattoo symbolize?

Koi Dragon Tattoo

The koi fish in Japanese folklore represents the overcoming of obstacles, because the koi fish travels up the yellow river and when it comes to the end of the river it transforms into the dragon; thus overcoming the adversity represented by the strong river to fufill its own destiny.

The Koi is the symbol of strength and will, the will to go against odds to reach the destiny. And the Dragon is the power and ferocity. The mystery and Aura.

The Koi Dragon is all about a re birth or new start/ begining. I.e. After a divorce/ bereavement signalling a new chapter in a strong willed persons lifrte. Thus enabling them to move on and start afresh.

Edit: Most of this is correct except actually it is a waterfall that a Koi climbs. Not a river. For the waterfall represents challenge in life. If the koi can manage to climb said waterfall he will become a dragon. Another words if one is able to overcome obstacles/challenges they will be greater for it
