HISTORYThe angelfish Pterophyllum belongs to genome belonging to the family of cichlids. Many people refer to them only as "Angels". Los Angeles Pterophyllum wild live in the calm waters of the Amazon River and Guyana in South America, and in small streams connected to these great rivers. The waters of these rivers are full of algae, and plants growing in compact way, because this is the thin, elongated angelfish body, this body helps them to move between the compact river vegetation, without getting caught. The body of the angel fish is round like a record, and very thin. When angelfish anything, keeps the body thrown upwards, and their large fins, doral, pectoral and ventral fish gives an appearance of being very large. |
Zeus scalaris angelfish was first described by science. A man named Liechtenstein caught this fish in Brazil in 1823, then this fish was sent to the Berlin Museum, a man named Heckel found another angelfish, Pterophyllum scalaris and call, Pterophyllum meaning "having wings like leaves." Today angelfish is they called Pterophyllum scalare, but this name was not used until the early 19th century. Scalare name was given because the doral fin is regarded as a "ladder." In 1917 were officially introduced in the United States, a high price for a pair of Pterophyllum scalare was paid to one week's salary. In 1980 the sale of these fish had a spike, and these fish were literally in any aquarium for sale as "farms" were established in Florida, today is a very common fish and you can find it for sale in any aquarium . Recent findings indicate that angels bred in captivity originated from several species and not just the wild Pterophyllum scalare. Many of the players on the pitch angels were devoted to keeping track of the family tree of angelfish reproducing. Even many of the players were not able to distinguish between different species. Many scientists today even still have trouble identifying them and ensure that the species contains several species Pterophyllum scalare. The Pterophyllum scalare Wild exhibit substantial changes in your body even to different size scales. Even some pre-flycatchers have fins, which are not defined and described in the species Pterophyllum scalare. What's certain is that we have our angel fish in our aquarium is the result of the reproduction of different species over many years of angels found in aquariums players.
Obviously we have angelfish in the aquarium can also be the result of random mutations or even unintended mutations. Significant mutations occur frequently and for the past 50 years of playing the angelfish in captivity over 25-35 significant mutations have occurred. Minor mutations can gradually change the characteristics of a species and that accumulate over several generations.
