~~霓虹Neon 藍~~

Doubtlessly the albino version of the strain shown above has been out crossed to strains with much finer fins and form, and raised in more optimal conditions. However, the basic genetics of the fish are the same, right down to the white patina you see on the head and back of this strain.

The Taiwanese are not the only guppy breeders to go fishing in the fish farm. The Neon Blue is the foundation strain for the beautiful Japanese Blue Glass guppy. In fact you find a lot of Neon Blue genetics in Japanese blue strains, although the Japan Blue has more recently been used for its shimmering light blue quality. The Neon Blue has the tuxedo (half-black) pattern.
GeneticsThe base strain for this variant is a red half-black guppy! The neon blue color is a product of the neon blue mutation often referred to as "blau," the German word for blue. The mutation is also called the "neon blue mutation."
When you acquire the Blue Neon guppy from a breeder, rather than a store, you actually acquire both the red and blue variations. That's because the Blue Neon is actually a hybrid with heterozygous blue and red alleles. The Blue Neon is created out of a Red Half-Black guppy by crossing to a guppy with the blue neon mutation, variously called Silver in the U.S., Blau in Europe or Brao in Japan. ("Brao" is a variation in the spelling of "Blau.")
The blue neon allele is autosomal recessive. When the guppy is heterozygous for the blue neon allele, the blue iridescent color is produced. When it is homozygous for the blue neon allele, a dull, colorless phenotype is produced.
Since the neon blue mutation directly affects the body and not the fins, it is possible to have a blue neon fish with red fins. That is, the fins are given color by their own color genes. However, there is some influence of the body color genes on the color of the fins. Blue neon mutants with red fins tend to have darker, more dull red than grey, gold or albino guppies.
The homozygous blue neon mutants tend to be smaller and somewhat more fragile than their siblings.
Basically a guppy homozygous for the neon blue mutation is crossed with a red version of the strain. This produces males that are heterozygous neon blue. The red color cells are replaced by a bright, brilliant blue iridophores.
