Easy :-)
the lecky yellow is basically a melanistic fish. google image 'white knight'
and electric blue for an extreme example.
That means it has very little of the black pigment in it.
Now many have 'dirty' genetics and grow up with black spots.
But what usually happens is people feed a food high in these darker
pigments!
Think of the johanni, the female is yellow and the male black.
feeding food high in astax will flood the female cells with pigments only
the males usually bother to make.
The result is a female with male colours.
Yellow fish like the electric yellow often get dirty brown patches.
The good news is that if you stop feeding the enhanced food it will drain
out.
Bad news is that if you have been feeding for a while it can take some time.
A much better solution for better colour is to blend up prawn (shrimp for
you freekin yanks) shells and heads, mix it 50/50 with vege like
peas/spirulina powder zuccini and yellow squash and capsicums, maybe a
sprinkle of vit C and paprika as well. I crack an egg into the blended mush
and then mix it with a strong solution of disolved agar agar or geletine and
water. SImply pour into flat bags or ice cube trays and freeze.
This food can be googled for under 'european shrimp mix'
now to read the replys and see if i just repeated meself ad nauseum!
