I was watching an episode where I believe either Ami or Garver tattooed a guy that wanted a koi fish with a dragon head. I have been researching and I cant find what its called. Im not sure exactly the meaning either. I know that the koi swims upstream and if it crosses the gates it turns into a dragon. Well I guess what Im talking about is it being half way through this transformation stage. Im just trying to find the name of the creature and its actual meaning. Also if anyone has a picture of the tattoo ami did that would be great. heres a pic I found.

It is, to the best of my knowledge, called a koi dragon.

I have been trying to do some research on them and the picture above is the only one I can find. I really cant figure out its sybolizm either. Except its in the middle of its transformation? If anyone else has any info that would be great.

If you are referring to the image of a carp leaping through the Dragon gate I am not sure if the transforming carp has a special name.
