The wild discus Blues have the brown or yellowish body and the head with bluish streaks. They are the most colorful and with greater blue intensity in the dorsal part and head. They can present the dorsal fin in the coloration between red, orange, black or blue. The so-called royal blue has the whole body covered with bluish streaks, while the semiroyal presents in the center of the disc only traces of these stretch marks. There are fish with blue tint on their face, are rare and called blue face or Willischwartzi. There is a variation called blue moon, which features a blue moon half on the ventral curve of the fish, including the pelvic and blue-anal fins.

Wild discus are fish that live in small shoals. They separate themselves in pairs only at the time of reproduction, usually between the months of January and February. In nature, in times of piracema, the discus become aggressive, thin and ugly. They protect the eggs and nourish the puppies with the mucus of the body itself. It is common to find them in pairs in the stumps of the bushes of the flooded forests. In this period, if they are caught, they end up falling ill and can hardly recover. So during the playback of the wild discus, they are not disturbed by the fishermen. In February the water of the rivers has already risen a lot, and the wild discus and their pups disappear in the flooded forest. For this reason, the harvest of discus takes place only during the dry season, between August and December.

In nature, wild discus may have red, yellow, or black eyes. They can show the outline of the face rounded or sharp. They may present with a smooth body or full of bluish or whitish streaks. The color of the body can be yellow, orange, brown, gray or blue. The dorsal fin may vary in coloration from red, orange, black and blue. The skin color of the wild discus can be modified or intensified according to the dye added in the ration it feeds.

The value of the wild discus increases if it has red eyes and no beak. Some photographers conceal the mouth of the fish discus by hand to cover up the imperfection of the beak.

If the fish is stressed, it darkens their 9 vertical lists and also darkens the body and retracts. When you go to choose a wild discus to buy, prefer what comes to you. He is probably young, friendly, adapted to the life of the aquarium and is asking for food.

When a fisherman catches a lot of wild discus, he normally stores in boxes of 200 fish, among which he will discard only those marked by bites, large eyes and the diseased ones. In this lot, probably only 10 wild discus will have red eyes, your mouth will not form a beak and your body will be full of stretch marks - royal. So unless you're getting the fish for reprodution, you'd better buy a small group of 6-10 more simple variety.

Unlike breeding farms where couples of red-eyed wild discus are formed to produce similar offspring, and if it does not work, the breeder can cremate the offspring and redo the process, companies that buy wild caught fish alive in Brazil depend on the nature and can not kill the purchased fish. This is why there is a great variation in the price of wild discus, but regardless of its rarity or simpler classification, wild discus are docile animals, beautiful and easy take care, provided they are kept in high temperature water and in small  groups because they are warm-weather animals, gregarious and can not live alone.
