Red Turquoise Discus originate from the Amazon River Systems of South America, where they were first imported into the aquarium hobby in the early 1930s. Ever since their introduction into the hobby to this day, Discus are considered one of the most colorful, demanding, rewarding and expensive of all tropical freshwater aquarium fish species. Due to their popularity and the high price tag that they command, Discus are very popular with fish breeders. Over the years breeders have not only raised enough tank-bred specimens to largely fulfill the demand from the aquarium hobby, but have developed completely new color strains and patterns as well. Discus are very popular amongst intermediate to advanced fish keepers, and are widely considered to be one of the most rewarding and challenging to keep of the freshwater tropical community fish species available within the hobby.
In the wild, Red Turquoise Discus are found living in the upper tributaries of the Rio Negro and Rio Madiera along with the surrounding lakes and flood plains. The water is very low in mineral content, which makes it "soft" water with a low pH ranging from 4.0 to 7.0. The water also maintains very stable and consistent water parameters year round, including water temperatures that range between 80 to 86 degrees Fahrenheit both during the day and night. When keeping Red Turquoise Discus in the home aquarium, it is extremely important to replicate their natural surroundings and water parameters as closely as possible. It is also very important to maintain very consistent water parameters that have very little pH, temperature and dissolved mineral fluctuations.
Red Turquoise Discus aquariums should closely resemble their natural Amazonian habitat with plenty of plants and branching root. Water parameters should be very consistent with a pH near 6.8 to 7.2, temperature between 82° to 86° Fahrenheit with low to medium water currents. Discus can thrive in a wider range of water parameters as long as the changes are not sudden and the fish has adequate time to adjust to changing parameters. Red Turquoise Discus should not be housed with aggressive or boisterous fish species or in aquariums with intense lighting or strong water currents. If strong aquarium lighting is used for plant growth, be sure that the density of the plant life is great enough to provide shaded areas for the Red Turquoise Discus to retreat to when needed. Strong biological and mechanical filtration along with weekly partial water changes are required to keep water quality high and water parameters consistent. When keeping Discus with live plants, it is best to keep the aquarium pH between 6.0 to 6.8 and a lower water hardness of 150 PPM or less. Lastly, be sure to maintain excellent water quality at all times as Discus do not leave a lot of room for error when it comes to water quality and consistency. Recommended tank mates include: most Tetra species, loaches, cory catfish, smaller Plecostomus species, Siamese Algae Eaters, Ottocinclus, Rams, peaceful Rasbora species, Rainbow fish, Hatchet fish and Pencilfish.
Also known as Ruskokiekkokala, Scheibenbarsch, or Diskusfisk.
The body of the Discus is round and laterally compressed, an unusual characteristic of the Cichlidae family which makes it suitable for gliding through tall aquarium grasses. Discus are vibrantly colored with vertical or horizontal stripes. Needs plenty of hiding spots especially tall live plants.
These fish require special attention, needing low lighting and soft water. Dark substrate will also reduce the amount of light reflected around the tank. Water conditioner or Reverse Osmosis Filtration to soften the water is highly recommended.
