Green Delta (Green Triangle) Guppy – History, Description, Genetics

History

One of the oldest green guppystammen is Parrish Green.
In this tribe voting the color of dorsal
and tail fin does not match well,
with the dorsal fin is usually lighter in color than the tail.
The Guppen from this strain are considered big and strong,
although this reputation by inbreeding a serious blow to it.
U.S. guppykweker Hutter developed a strain in which the green color
of the fins are the same, and the strain was further developed by Regent.
Hutter’s greens are smaller,
more beautiful in color and slightly less strong.
By extensive inbreeding, he knew the good qualities of both strains together.
The names “Parrish Greens” or “Parrish dorsal” often refer Guppies
with white spots or patches in the dorsal fin,
while the term “Hutter’s Greens” refers to oevereenstemmende check peddling.
Because these green Guppies often been cultivated strains were different,
these terms have lost much meaning.

Description

This must be one of the most disqualified Guppies are the IFGA shows.
How beautifully green this guppy in its propagator can see out,
once under the exhibition spotlights many are blue or purple.
This has to do with the color structure in the guppyhuid.
The only difference between blue and green guppy
is the number of yellow pigment cells present therein.

Structural color is caused by light reflected from the iridophoren
or reflective color cells.
In this case the blue light waves reflected.

DE reflection angle and color temperature of the exhibition lights
are reflected from the iridophoren
and this can present color of the guppy effect or change.
Because judges must evaluate their eyes
– and not with presuppositions
– these Guppies is often not enough green coloring
in the artificial lighting in exhibitions, to qualify.
