Grass Strain

January 23, 2007 at 11:50 pm | Posted in Grass Strain, Guppy Strains Library | 3 Comments

Grass originated from Japan and is a variation from Mosaic.

Before that , in 1970s Japan imported the Glass from Singapore. One of the Japanese breeders crossed the Mosaic with this Glass. In the late 1970s to early 1980s, the outcome of the cross resulted in the Glass Mosaic where later termed Grass.

It’s also suspected that the Mosaic used in the cross was from Germany. Mosaic was already imported to Japan from Germany in the 1960s. Thus the early Blue Grass will not result in Red Grass.

Also in the early 1980s, Japan has brought in guppies with the Bb genes from Singapore. And this is also how the current Blue Grass produces Red Grass as they may contain the Bb genes.

There is also another ‘story’ about Grass origin. It is said that in Japan, a breeder spent 10 years over 25 generations inbreeding the Tuxedo Mosaic. After overcoming much difficulties in his breeding, it resulted in the Grass strain where it’s not his main aim.

Whichever origins it come from, it seems that Grass originate from Mosaic strain.

There are basically two types : the standard Grass type which the tail color is not impressive and the other type is the Glass type where the tail is more transparent and more finer dots. As such sometimes you may find both strain names as Grass and Glass. Even though as such, sibling cross of grass strains will still produce both Grass and Glass and therefore such classification is not necessary.

This Grass gene (X[sup]GL[/sup]Y) will affect the caudal and dorsal fins. Therefore it is important to choose both caudal and dorsal with similar Grass patterns.

In Noboru Iwasaki’s book – Fancy Strains and How to Produce Them, 1989;
– Blue Grass was produced by crossing with Neon Tuxedo.
– Red Grass was produced by crossing with Red Mosaic.
– Yellow Grass was produced by crossing with Leopard.

There are also other types of Grass like;
– Full Metal Blue Grass which is a Blue Grass that has been crossed with the Moscow.
– A bronze version of the strain in Japan called Tiger. It has a metallic sheen which is due to the metal gene added to it.

Now take a careful look at the differences in the female caudal shape;

Termed the Genuine Female where the top part of caudal is more pointed upwards and bigger. This is said to be the result of crossbreed with Mosaic.

Termed the Normal Female where the caudal is more rounded and lighter color. Such female is more preferred if I’m not wrong. The round tail tends to produce fan tail fries and will not affect the fin pattern of the male sex.

Full Red

There are many types of Full Red, and they are basically;
– US Full Red
– Moscow Red
– Coral Full Red
– Holland Full Red

and the cross breed of the above.

US Full Red;

Characteristics : All red except the head top is not red. Usually the belly part will slowly colored up. Body chromosome – ff. Somehow the term US Full Red is rather confusing, maybe US Red will be better.

There is another Full Red (which is a TM of Ed C.) from the breeder Ed Chiasson.

His Full Red again is divided into 2 version : Grey and Blond body version.

Grey body version : The color is deeper but after sometime, there appears black dots near the caudal penducle.

Blond body version : The color is more lighter.

Both version, the red is already fully covered up when young. To maintain a good line of Full Red, it’s best to cross breed both version.

Moscow Red;

Characteristics : The color is more orange red if compared to the US Full Red due to the Blond body. Thus the color of caudal is also affected. But because of the Blond body, the whole body is fully orange red which is like the Moscow Blue (fully blue).

The whole fish is colored up except the head top, while the belly usually colored up later.

Body chromosome – ff. Both the male and female must have the Moscow gene. The body is thick and the caudal angle is wide too.

The female dorsal lacks the red color, while the caudal color is thicker.

Coral Full Red;

Characteristics : All red except head top and belly not fully colored up. The obvious part is the coral red line right behind the eyes across the body. Y linked.

Albino Red Head Coral Red Tail;
Characteristics : Same as Coral Full Red except that the head top part is colored up.

Holland Full Red;

Characteristics : It has Red Head gene, Y-linked and the color is lighter than Moscow Red. The dorsal is big and color is more even. Though there may be some exception.

The fish originated from Germany. Initially, the fish is Red Head Flamenco Red with Full Red gene but of wild body (this line will gives blond, albino and wild body).

Then why is this called Holland line? That’s because during that time, there was a fish exchange programme between Germany and Holland, and in the production of this fish it’s in Holland, thus it’s called Holland line.

Platinum El Dorado

Not much infos on this strain though it is one of the purest strain. It has a real gold platinum body. The El Dorado belongs to the Stoerzbach metal group too.

The Stoerzbach metal are recessive, autosomal (these genes are located on the body-chromosomes, the autosomes). So male guppy shows (in most cases) all traits of a strain while the female guppy shows only some traits of a certain strain.

What distinguishes the El Dorado is the presence of a Schimmelpfennig platinum gene on the Y-chromosome.

In 1990, Hiroshi Sugino crossed a German Schimmelpfennig Lyretail with an Old Fashion guppy. Some of his F1 produced a delta tail and he crossed this F1 to a Japanese Mosaic strain. This is thought to be how the original Platinum El Dorado was created. The name ‘El Dorado’ given by a Japanese breeder which means “Lost City of Gold”.

Flamenco Red

January 23, 2007 at 8:20 am | Posted in Guppy Strains Library, Solid or Plain Color Strain | Leave a comment

Characteristic : There is a coral red line behind the eyes and the belly is not colored up. The body is thick and the dorsal and caudal angle is wider.

The female :
– Some female dorsal rear part is blood red in color.
– Some female dorsal has no red color but caudal is orange in color. Some female caudal may also exhibit mosaic pattern.

Albino Red Head Flamenco Red;

Characteristics : This is Y-linked. There is a coral red line behind the eyes and the belly is not colored up. The top part of the head is red and this is more obvious for the albino strain.

The Lazuli guppy was named after the color of the aquamarine blue of the Lapis Lazuli gem.

The original creator of Lazuli is Taketoshi Sue and it first appeared in 1999. The Lazuli has an additional color gene on it’s Y-chromosome thus making the blue head. It’s basically a Japan Blue with this extra gene.

The Lazuli Mosaic was subsequently created in year 2000 and thereafter there are various types of Lazuli.
