Swordtail fish, alias swordfish, green sword. Swordtail fish in the water temperature of 20-25 °C, weak acidic, neutral or slightly alkaline water can grow and reproduce normally, the most suitable growth water temperature is 22-24 °C, omnivorous, mild personality, easy to polyculture with other tropical fish.
Red swordfish, is the most common swordtail fish on the market, is an artificial breeding species, swordtail fish is originally green, the body side has a red stripe, swordtail fish and moonlight fish hybridization, after artificial continuous selection and cultivation, you can get red sword, yellow sword, Mandarin duck sword and other different flower color varieties, tail fin has a single sword, there are also double swords (the upper and lower ends of the tail fin are extended). Hybridized breeds, such as red swords, grow fast, have strong physiques, are easy to raise, and have more ornamental value.
The sail fin red sword is a high-level breed that is artificially selected and purified, and it is more difficult to raise.
Blue Swordfish (Blue Sword)
Green Sword
The green sword is the closest breed to its ancestor, the swordtail fish, an adult male, with a light blue luster on the body and a red line on the body. The individual is also not very large, about 5 centimeters, swimming in the aquatic grass, especially aura. Once, the green swordfish was only improved by random hybridization because it was too "primitive", and did not maintain the original species, and the green sword that can be seen now is actually a hybrid species, and it lacks a lot of aura and luster. This is truly regrettable. At present, purebred green swords can only be seen in Germany and the United States, with the global perception of the beauty of ornamental fish, people in more countries have begun to advocate natural beauty, and now in Japan and other places, the price of green swords is higher than the best red and white swords.
Red swordfish
Red Sword
Small fish, adult individuals 7 to 10 cm long, spindle-shaped body, head and tail length. The red swordfish is red all over the body, is a colorist in the aquatic weed tank, the male carries a long sword, the female wears a round skirt (round tail), the gender characteristics are clear, and it is also rare in other fish. Red swordfish are easy to hybridize with moonlight fish. If you have moonlight fish at home, please keep them separately to ensure the purity of the red swordfish species.
Apple Sword
The appearance of the apple swordfish has some of the original characteristics, which is a breed obtained by the red swordfish hybridizing with other swordtail fish.
Red and white sword
The red and white sword was cultivated in Japan, and at first the domestic red and white sword was called "X-ray", because the white part of the middle of the body could be seen transparently, and the bones and internal organs could be seen, and the head and tail were red. The recently modified red and white sword body is red and white, and the white part is no longer translucent. They can grow to about 250px, and sometimes there will be "Danding Sword", which should be the ancestor manifestation of the red and white sword, the body is blue-gray, there is a black line under the tail sword, and the eyes are black. Only the head of this category is red, hence the name.
Tricolor swordfish
Tricolor sword
The tricolor swordfish is a breed that was re-bred by the Japanese after the red and white sword, and is very small, with an adult age of no more than 150 px. Red, black and white tricolor pattern on the body. According to the Japanese, there are three colors without black patterns on the mouth, and some are Showa, which is almost the same as koi. At present, the color of the three-color sword is not very beautiful, especially the red area is not obvious, with further improvement, I believe it will be gradually improved.
Mandarin duck sword
Mandarin duck swordfish is an earlier artificial breed of swordtail fish, similar in appearance to red swordfish, but there are obvious black markings on the back of the body, which is speculated to be derived from hybridization with the native Meyer swordtail. Mandarin duck swordfish are not as large as red swordfish, and the largest female is only about 10 centimeters.
Gao Fan Red Sword
Chrysanthemum sails
Wolf's Tooth Sail
The high-fin red sword produced in Beijing and Tianjin has a very large adult dorsal fin, and if the male fish fully opens the dorsal fin, it can become a huge fan shape. Unfortunately, the fins of this type of high-fin red swordfish are soft and not easy to stand up. The red swords produced in Anshan and parts of the northeast region, the first fin of their dorsal fin is very hard, can be erected for a long time, and has a tip at the end, just like the canine teeth of the big bad wolf, so it is called the "wolf tooth sail red sword". By the end of the 1990s, the fish had begun to take shape, but its dorsal fin was not as large as it is now. After the northeast region enthusiasts again improved this variety to stabilize.
