Xiphophorus hellerii Wagtail Red White

17. August 2020

The pretty swordtail breeding form Xiphophorus hellerii Wagtail Red White is still young, it was only created in our millennium. The animals are descendants of the red and white “Koi swordtails”, which by the way are mostly born red and in which the white areas only develop with increasing growth.

These fish have less silvery scale dye (guanine) than “normal” swordtails, therefore the gill covers appear transparent, the blood-red gills shimmer through. The red body colour in the red-white Koi swordtails – and thus also in the black-finned Wagtail variant – appears for the same reason as a kind of transparent orange-red, which gives it its special charm.

Xiphophorus hellerii “Tiger”

20. December 2019

Breeding marbled swordtails with red basic colour is a challenge. With the “Tiger”, which we can offer for the first time, this goal has succeeded. In every “tiger” the body spotting is individually different. So far that type of swordtails were offered almost exclusively with whitish body-basic-coloring (then one calls them Marble). Many of the black scales have a blue glimmer (in breeder circles one calls that the “mirror”) what shines splendidly and glitters with lateral incident light. In the age, the black coloring of these sword-bearers increases more and more. They are beautiful animals, which a German breeder could deliver to us.

Xiphophorus andersi

10. December 2018

Once again we can present and offer you a top rarity among the wild forms of livebearers: Xiphophorus andersi. Most likely the animals we have received from a German breeder are the first ever to be offered in the ornamental fish wholesale trade. 

Xiphophorus andersi comes from the Rio Atoyak in the state of Veracruz, Mexico, which is one of the Atlantic processes of the Central American country. The species was only scientifically described in 1980 and seems to occur only very locally. 

In this species there are small early males and large late males. In practical breeding it has been shown that it is better to leave both forms in the breeding line (many breeders tend to exclude the early males as “Mickerlings” from breeding), because otherwise there is the danger that the offspring consists only of animals of one sex (one cannot predict whether male or female).

The fish are demanding to look after. It is important to pay attention to the best water quality, generous, regular partial water changes are absolutely obligatory, so that these rare animals thrive well in the long run.

Xiphophorus hellerii „Hamburg Highfin“

19. September 2018

Only very rarely one of the most beautiful breeding forms of the swordtail comes to us: the black Simpson with orange fins. Among fish lovers Bayreuth is known as the spade for this very distinctive swordtail breeding form and is called “Bayreuth Cross”. In Germany, this variant was first exhibited in 1968 (report by the Nordbayer Kurier on 11 October 1968). As with other swordtails – Hamburg, Wiesbaden, Berlin – the name of the city was adopted for this helleri and thus it became the Bayreuth swordtail.

However, this was not the first time that a swordtail of the “Bayreuth type” was bred. In fact, five years earlier, Hawaiian fish breeders Eric and Larry Nishida crossed a red Simpson fin male with a normal fin Hamburg female. Hamburgers are black swordtails whose scales have a green or blue sheen. The result of this crossing had the high Simpson fin, the body coloration of the hamburger, a well developed sword, a bright red throat region and red fins.  An article about this “Nishida Highfin-helleri” appeared in the American magazine “The Aquarium” in November 1963.

Our fish are offspring from Vietnam.

Xiphophorus hellerii „Kohaku“

1. August 2018

Red-white, koicoloured livebeares are very hip currently. Usually the commercial breeders do not name their creations by their genetic compostion – like private hobbyists do -, but name them instead with as fancy names as possible. The „Kohaku“ is a white albino swordtail with a bright red patch on the front part of the body. This sport is known for some time already with black eyes. This was named „Marlboro“ and the selection with the red patch on the front part of the body „Tanchu“. No doubt: the albino selection called „Kohaku“ is a real eyecatcher!

Xiphophorus meyeri

18. April 2018

The marbled platyfish (Xiphophorus meyeri) belongs to the rarest animals in the world. It is known only from a small area in Mexico and even there it is found only in a few places. This is the reason why this species is considered to be endangered, as like in its close relative, the Monterrey platy (X. couchianus) the demand for water in the region is rising and the few natural habitats are in danger to dry out.

So it is very good the some enthusiasts keep and breed this fish despite it is – compared with the colorful sports of the typical aquarium platys – a rather drab coloured animal. Thanks to these hobbyists the species may survive. From time to time even here in the wholesale trade some specimens appear. The fish we currently offer are German bred ones. This wild platy attains a length of about 3 cm (males) and 4 cm (females). Keping and breeding can be roughly comared wth hat of the variable platyfish (X. variatus), but X. meyeri is by far less productive.

For our custimers: the fish have code 476532 on our stocklist. Please note that we exclusively supply the wholesale trade. Available in small numbers only!

Xiphophorus hellerii King Lyratail

13. October 2017

Lyretail swordtails are a sport of Xiphophorus hellerii and rather difficult to breed. Usually only the females can be used for breeding. They need „normal“ males for mating, because in most Lyretail males the fin that is used for insemination in livebearers, the so called gonopodium, is much prolonged and useless. Among ornamental fish breeders the word of „playing Mikado with cooked spaghetti“ is well known… If one uses „normal“ males for breeding Lyretails only a part of the offspring has the Lyretail phenotype. This is the reason why Lyretails are usually more expensive than other sports of the swordtail.

But very rarely Lyretail male swordtails appear that have polonged fins, but a normal gonopdium. These are called „King Lyretail Swordtails“. Dieter Bork has bred King Lyretails for us that are already offspring from King Lyretail fathers. The latter have been selected by us from imported Lyretails. Most of the fish belong to the sport „guentheri red“, but some other sports are also among our fish. The King Lyra females usually develop a small sword when fully grown.

The King Lyra swordtails we currently have in stock are most probably the very first ones that appeared in the ornamental wholesale trade at all, they are a real top-rarity!

For our customers: the fish have code 420823 on our stocklist. Please note that we exclusvely supply the wholesale trade. Available in limited numbes only!

Xiphophorus hellerii „Broccoli“

11. August 2017

What is a Broccoli swordtail? A green swordtail that smells like cabbage? No, not at all! If one crosses a simpson swordtail – simpsons are the swordtails with the long dorsal fin – with a lyretail swordtail – lyretails have prolongations in all fins – some of the offspring have a very long simpson dorsal fin. In these fish single rays of the dorsal fin are longer than the remaining ones. This was felt not to be attractive for a long time and the cross was also excluded from competitions. But in Asia people saw the things different. They continued developing the cross and finally the result was a fish in which the extraordinary large simpson dorsal had wavy structures along the edge. The breeders named the new sport „broccoli“. We now have received for the vey first time some of these swordtails, bred on red albinos. The red albino sport in X. hellerii is called the „Vienna cross“.

Xiphophorus hellerii „guentheri Golden Stream“

8. February 2017

Once more we can present to you an interesting and beautiful wild variety of a livebearer: Xiphophorus hellerii „guentheri Golden Stream“, This unusual Green Swordtail originates from the surroundings of the Golden Stream preserve in Belize, Mexico. This presevere covers an area of about 61 km2 and contains a large number of rare and endangered species. Our specimens of Xiphophorus hellerii „guentheri Golden Stream“ are bred ones from Southeast Asia.

In Germany usually spotted swordtails are called „guentheri“. The subspecies Xiphophorus hellerii guentheri has been described from Guatemala. The „Golden Stream“ does not fit to what we think is a guentheri, but the name has been accepted widely in the community of liveberaer enthusiasts so we feel that the name should not be changed without eager need. It is by far more important that such animals are bred in pure strains. Only under these conditions it will be possible in the future to study behaviour and genetics of wild fish. There do exist already enough artifical sports and crosses.

One of the pecularities of the „Golden Stream“ is that there still exists a natural polymorphism in males. One can obain from the same brood small, tiny, often very colourful males and real bulls that have about the double body mass compared with their small conspecifics. These so called early and late males appear initially in any population of swordtail, but in the domesticated strains the breeders often eliminate the small early males and so only large, late males exist. 

The males of the „Golden Steam“ often exhibit dark vertical stripes on the shoulder. All in all the „Golden Stream“ is a wonderful wild type of swordtail that can be recommended warmly to all hobbyists interested in studies of behaviour and genetics; but a hobbyist that simply enjoys beautiful fish will also make a good choice in buying Xiphophorus hellerii „guentheri Golden Stream“.
