Colorful Giants exist in the vast Amazon water system, the largest river in the world. Due to the wide spread of the recreational areas, it is even difficult to classify different species in many areas, and some new fish species are constantly being discovered. Although some experts Everyone wants to establish a classification standard for the colorful giants, but so far, the artificial colorful giants have only stayed at the two types and five subspecies that have been used for many years.
The Colorful Giant was born in 1840 when he was a fish and taxonomist at the Museum of Natural History in Vienna, John? Jacoba? Ugl (Johann Jacob Heckel), for Austrian Johann? The fish was officially named Symphysodon discus for the first time when Johann Natterer collected more than 50,000 animal specimens including 1,700 species of fish during his 18 years of exploration in South America. This was later called the Seven-Colored Giant of Ugor.
In 1904, the French taxonomist Jacques Pellegrin pointed out that the seven-colored giants produced in Taifei and Santarem (not wearing Ugurah and wearing it secretly) and the Uggl seven-colored giants (wearing Ugurah) I secretly admit) the fact is very different. A few years later, the American teacher Carl H. Eigenmann wanted to record it as a subspecies of Ugres discus under the name Symphysodon discus aequifasciatus. However, in 1960, taxonomist Professor Harald Schultz, However, this subspecies was officially corrected to another species, Symphysodon aeguifasciata, and two new subspecies were added to this species, making this species include three subspecies of green discus, blue discus and brown discus.
In 1981, Mr. Warren E. Burgess separated another subspecies from the Uggle discus - the Willis Schwartz Uggl discus, and the following 2 types of 5 are commonly used today. Subspecies classification.
Species 1, Symphysodon discus
Subspecies: Symphysodon discus HECKEL 1840
Subspecies: Symphysodon discus Willischwartzi BURGESS 1981
Species 2, Symphysodon aeguifasciatus
Subspecies: Symphysodon discus Willischwartzi BURGESS 1981 aequifasciatus aequifasciatus PELLEGRIN 1904)
Subspecies: Blue Seven-Colored Giant (Symphysodon aequifasciatus haraldi SCHULTZ 1960)
Subspecies: Brown Seven-Colored Giant (Symphysodon aequifasciatus axelrodi SCHULTZ 1960)
At the end of the regional adoption, each subspecies has the emergence of new fish that have no common regional manifestations. Therefore, although the above subspecies names are still commonly used, the regional name is often added to the subspecies name for newly created fish species, such as Isaac red, Goalli green, etc., to highlight its singularity.
