Is that the fishes get more human or the humans get more fishes?

I always thought that dogs, after living with their owners not only got the habits, but in some ways also the face expressions of them.
Now they found fishes that looked like humans.
"The "humanoid" carp are attracting attention in the town of Chongju in the centre of the country where they live in a small pond.

They are believed to be hybrid descendants of two carp species – the carp and the leather carp, also known as a tangerine fish.

Both fish are females and more than three feet long. They appear to have distinctive human noses, eyes and lips.

The fish live in a pond behind the home of a 64-year old South Korean man and have been there since 1986 although their looks are only just starting to attract attention."
