Habitat
Live in the Amazon’s middle and upper regions.
Maintains shaded areas in calm waters, particularly close to banks with wood deposits and coastal plant roots that form sturdy shelters.
Description
The body has a disc form and is firmly flattened on the sides. The mouth is tiny and the head is fairly small. The anal and dorsal fins are long rather than tall. The pelvic fins are longer, and the caudal fin is shaped like a fan. The female has a conical, blunt ovipositor during the spawning period, while the male has a pointed vas deferens.
Calm, shy fish that prefer to stay in groups in the middle layer of the water, they enjoy shaded areas and soft lighting.
It can be kept in a common aquarium, but it is preferable to have it in a species aquarium with a 40 cm water column height, where it will be surrounded by driftwood, floating plants, and thickets of plants with large leaves growing upward on shortened stems.
Water parameters: pH 5.8–7.2, temperature 28–31 C, and hardness (dH) up to 12.
Pay close attention to how clean the water and soil are. A few aquarists maintain their aquariums without any dirt. Mandatory weekly replacement of 1/5–1/4 of the water volume (one daily replacement of 1/10 of the volume is also made).
Feeding
Live, frozen, and dry food—ideally created especially for Discus—are all acceptable.
Breeding
Spawning in pairs. Six to eight specimens are combined to form a pair. By adding a fish to an established pair of male and female fish, you can ascertain the sex of the additional fish. It is a male fish if the male drives the fish, and a female fish if the female does.
Cleaning the substrate (a vertically oriented plant leaf, a stone, a snag, etc.) and trembling of the fish body are the first signs that a pair is ready to spawn.
It is best to remove the remaining fish or move the pair into a spawning aquarium that is at least 90 cm long and has spawning substrate (ideally without soil).
The spawning tank’s water has a pH of 5.5–6.5, a dh range of 1–3, and a kh of 0.
Up to 250 eggs are laid on the substrate by the female. The fish that looks after the eggs are usually the male, but occasionally both of them.
You must feed the fish in small amounts so that they consume all of the food while tending to the eggs and larvae. The fish become agitated and may consume the eggs or larvae when the remnants are removed.
The fry are incubated for two to four days, swim after three to four days, and feed on the unique secretions on the parents’ skin for approximately one month before being moved to the other parent to clean it. In certain instances, fish lack secretions, which causes the offspring to perish.
Fish have been known to fight for their young. In this instance, it is advised to divide the aquarium with a partition that is only one centimeter from the bottom, allowing the fry to swim between their separated parents.
Following five to seven days, the fry are given live dust (ideally red; in this instance, the fry’s reddened belly indicates that it is consuming food), and the water volume is maintained by changing it by 1/4 to 1/5 of its original volume every day. The fish are taken out once they stop providing the fry with secretions.
The second year of life is when the fish can spawn.
Every species has interbreeding relationships. Numerous color variations exist.
