Variations in well established lines.

I have the line with which I am working for some time now. Lately interesting phenotype has popped up.

Left one is golden/tiger

It is belived that golden is a single recessive mutation (gene was described long time ago). Fish need some tinkering here and there. I have two golden females so I guess it will be fun :).

Golden base coloration
No golden base coloration.

Both above males are brothers. Both has Y Schimmelpfennig platinum, autosomal homozygotous Pink and snakeskin in X. They are different only in base color.
