In 1859, the German ichthyologist Wilhelm C.H. Peters discovered the peacock fish in the Rio Guaire area of Caracas, the capital of Venezuela, so he became the first scientist to begin to describe this small freshwater fish, because the peacock fish seems to resemble the fish of the genus Medaka, so Peter Wilhelm named the peacock fish Poecilia reticulata.

The word Reticulata means that the partially overlapping scales of the peacock fish form a lace-like pattern (from which it is speculated that the earliest wild peacock fish probably carried a snake-like gene). (Image from IC photo)
In 1861, Senior Filippi of Spain received some specimens of peacock fish from Barbados, and because he did not see the description that Peter William had done, he mistakenly thought that he had discovered a new genus. (Image from IC photo)
Seeing that the peacock fish resembled poecilia, Xenel Philip called it Lebistes poeciloides (Frazer-Brunner, 1953). (Image from IC photo)
The name peacock fish waited until the British missionary Robert Lechmere Guppy was the first person to discover the peacock fish mentioned in the literature in 1886, after returning some specimens from Trinidad to be identified, and dr. Albert Gunther of the British Museum identified the specimen as a new species, in honor of Robert Guppy, so the "Guppy fish" was used. (guppy) is the common English name of peacock fish, and the English name of peacock fish is thus established. (Image from IC photo)
Peacock fish originate in Venezuela, Guyana, the northern coast of South America and some islands in the Caribbean Sea. Because the native peacock fish has a variety of color patterns, it is also known as a rainbow fish. Peacock fish eat mosquito larvae close to the water with their upturned mouth, so wild peacock fish were introduced to Singapore in the 1930s to control mosquito populations in mangrove swamps (Herre, 1940). According to various sources, the practice of enjoying improved peacock fish began as late as the 1950s. (Image from IC photo)
The history of China's peacock fish will not exceed 10 years in terms of introduction (the peacock fish commonly known here is based on the strain of peacock fish). Originally introduced by traders, most of the systems came from the Japanese system, and a few were Ashkenazi systems. In fact, the rules and breeding styles of Chinese competitions are mostly biased towards Japan (especially the fish of the grain system such as grass tail, snake pattern, mosaic, etc.). (Image from IC photo)
Under the competition of Chinese players to breed and improve, the quality of fish such as mosaics, grass tails, and snake patterns has the strength to compete with Japan. In fact, the development of mosaics is quite different from that of Japan. The Japanese side believes that the tail of the mosaic should be composed of three colors: red, yellow and black. Taiwan prefers black on a red background or black on a blue background. The tail and caudal fins are more colorful. (Image from IC photo)
In nature, there are generally fewer individuals with a blue hue. Yoshiki Tsutsui (a well-known Japanese peacock fish professional improver who participated in the initial improvement of the grass tail strain) has caused a considerable trend since the introduction of the Moscow blue (a peacock fish phenotypic) system to Japan in 1996.

At one point, the number of people raised may be as high as more than 50% of the total number of peacock fish players. The monochromatic group is often a whole moscow blue world. However, due to the large number of breeding populations, and the large size of the fish, easy to raise, resulting in the collapse of the entire price. In the absence of profit from many breeders, it slowly retreated. (Image from IC photo)
Peacock fish body length, male and female fish body size and color difference is larger, male body thin, body length 3-4 cm, female body length 6 cm, its tail stalk and tail fin account for more than 1/3 of the whole body, each fin is shorter than the male fish. The anterior part is slightly wedge-shaped, and the posterior part is flattened laterally. The abdomen of the female is expanded and rounded. (Image from IC photo)
Peacock fish is petite in shape, and the patterns on its body are colorful, some are shaped like letters, called foreign peacocks; some are like snake patterns, called snakeskin peacocks; some are like leopard skin, called leopard tail peacocks, and so on. The dorsal fin is long, the caudal fin is wide and long, accounting for more than 1/2 of the total length, the length of the caudal stalk is greater than the height of the caudal stalk, the dorsal fin is soft striped 7-8, and the fin soft strip is 8-10. Its body and dorsal fins, caudal fins are colorful in color, mainly red, blue, black, yellow, green, tiger skin and variegated. There are blue-red round spots on the tail fin and the abdomen, and there are pale patterns around it, resembling peacock tail feathers, hence the name. (Image from IC photo)
Peacock fish body back side flat, tail shape is diverse and gorgeous and beautiful, according to the shape of its tail fin, can be divided into upper sword tail, lower sword tail, double sword tail, piano tail, needle tail, round tail, flag tail, fan tail, triangle tail, pointed tail, long tail, tooth tail, large tail and other varieties. The hybridization of various species produces a variety of offspring, so although the peacock fish has many varieties, it is difficult to find two peacock fish with exactly the same tails, which is also the charm of the peacock fish.

It inhabits warm springs and overgrown ditches and canals. Occurs in a variety of habitats, from ponds, canals and ditches with high turbidity at low altitudes to pristine mountain streams at high altitudes. Can tolerate a wide salinity range, but requires fairly warm temperatures (23-24 ° C) and calm waters with vegetation. (Image from IC photo)
