same fish but some weeks older
blond (aka golden) brother
These pictures are out of my european blue tank.
I crossed the basecolor "blue1" to a comercial-traded "flamingo-guppy", which I got from a petshop. Now I have the first pair of "european white guppys". The difference to "asian-whites" is, that they are homozygous "blue/white" and they are showing red color in the caudal.
