Where are discus fish from
Bright, colorful, stately, hurried, elegant – these qualities are characterized to discus fish, photos of which inspire even those who are indifferent to the inhabitants of the underwater world. The name of the fish got because of The Shape of the body-round, flat, similar to a computer CD. The home of the discus fish are from countries of South America, the waters of the Amazon river.
Discus is one of the most beautiful inhabitants of the aquarium. This fish is rightfully called the “king of aquarium fish”. In nature, the discus fish are from: the mouth of the Amazon, the Orinoco, the waters of Brazil. They were transferred to us in the sixties.
Some experts believe that there are two species of these fish, while others claim that it is a single species with several (up to eight) geographical breeds and color variations.
The body of the discus is strongly flattened from the sides and almost round, disco-shaped, max length-20 cm. The pectoral and caudal fins are transparent, which further increases the resemblance to a circle. On the light gray, light, or dark brown background of the body of the discus are transverse more or less bright wide luminous stripes. Sex characteristics are poorly expressed, it is possible to determine the sex of the fish only during spawning.
Experienced fishkeepers perform relentless breeding work, achieve perfection of shape and color variety of fish, increase the number of stripes, their width, and color intensity. Such variations as blue Royal discus and cobalt discus are derived. The luminous bands of these fish are expanded and occupy the entire body area. The fusion of the bands made the cobalt discus like a sparkling emerald.
Particularly beautiful is one of the varieties of discus Discus Red, which, in contrast to other color forms, are not brown, but wine red.
These discus fish are from the amazon river so the conditions to hold all discus types are the same, so they are held together.
To achieve spawning of discus – it is very difficult, but interesting. It can only be successfully implemented if all sanitary and hygiene regulations are complied with.
Water for spawning must be specially prepared. You can use desalinated with Ion Exchange columns, but after distillation it must be defended for 10 days to stabilize the parameters, or distilled in a mixture with tap water, boiled for 15 minutes. Then it is stabilized with UV rays. Water hardness is chosen in the range of 4-4. 5°. It is extremely important to obtain the required acid, which can only be controlled on an electronic pH meter. The water should be slightly acidic (pH-6,7). Orthophosphoric acid is used for these purposes. The water in the spawning area is constantly ozonated and passed through a filter with activated carbon absorber to remove protein substances.
At the bottom of the spawning area, a net is laid, one or two ceramic pots and a bottle with an elongated neck are placed, on which the producers lay eggs because of their narrow and high shape. In the spawning water, add a liter of water that has been in a dark place with a Limnophila branch for at least a week after passing it through a mechanical filter. So prepared
this reservoir should be without fish for at least two days. Since that time, a biological filter is constantly used for complete water purification.
A pair of discus are placed in the spawning area in the evening. In the morning, the producers clean the place where they will lay eggs in the future. Such “cleaning” can take up to two days. During this time the fish are fed a moderately large scarlet bloodworm.
It is desirable that spawning is carried out in the morning before 12 o’clock in the afternoon. This becomes clear when you follow the birth of fry.
The female lays eggs in a pre-cleaned place, the male follows her-and so cyclically until spawning is over. Immediately after spawning, a solution of tripaflavin is added to the water until an emerald green color is obtained. Without this, it is very likely that the caviar is white, covered with saprolegniales. After two days, under the influence of external factors, tripaflavin will break down, and the water will become transparent again.
On the third day, larvae form from the eggs, and the parents begin to transfer them to another pot, where the place is already prepared. All the time, the producers fan the eggs with their fins, create an influx of fresh water and massage the embryos. On the fifth day the fry begin to swim, and then it is necessary to take into account the natural feature of the parent discus. Fry should swim up to 17 hours until you can use the nutritious secret on your parents ‘ skin. This secret is the only food for fry in the first days of your life.
After spawning, the male plays its crucial role-the transfer of the larvae from one place to another. Then it can be deposited so that it does not disturb the female. If the female was raised in a spacious aquarium and reached a large size, she will easily feed the young herself. Everything should be natural to their natural environment. Discus fish are from warm tropical amazon region.
On the third day after swimming, they must be fed with a pure culture of rotifers or Artemia. After a week, the fry will sink to the floor, and then you can give a cut tubifex to ensure that no excess food remains on the floor. The main food during this time remains the parental secret. The size of the female is also important because between the first and third, seventh and ninth stripes on the body of the fish a small amount of secretions is released.
After spawning, the producers are fed large mosquito larvae as before.
After two weeks, the eyes of the fry turn Golden. From this point on, it is necessary to increase the water hardness in the spawning area and add even harder water. After three weeks, the female can be separated from the offspring. Female discards the fry does not allow them to pick the nutrient secret, the release of which is significantly reduced at this time. Juveniles are transferred to small Daphnia or to brood of viviparous Daphnia. The hardness should be brought to 9°.
After five weeks, the young fish are placed in an adult aquarium.
Aquarium for discus
Remember that discus fish are from amazon river with highflowing water so the discus tank should be the largest available to the fishkeeper. When kept in small reservoirs, fish have increased puberty.
The number of eggs in these specimens is lower, and the fry that came from the eggs are weak and susceptible to various infectious diseases. The aquarium, with a capacity of more than 500 liters (1700x500x600) has the necessary length and a large width gives the impression of perspective. Then you have to make it as close to the underwater landscape as possible. The aquarium is decorated with hooks, large black stones that should be used for fish shelters. Plants need to choose large-leaved – some species-Echinodorus, Cryptocoryne. Create a background with Limnophila and Cabomba.
Since the growth of fish is negatively affected by the presence of protein residues in the water, which appear in it as a result of the vital processes of aquarium inhabitants, an aquarium of sufficiently large volume and length is necessary for growing full-fledged producers. In addition, it is necessary to organize water filtration through an outer filter and remove the pre-nozzle with silver to prevent plant suppression. It is possible to use an ozonizer, but organic substances are not removed, but bind to atomic oxygen and get into water-insoluble compounds. Such substances are poorly absorbed by plants, which inhibits their growth and development. The best solution to this problem is to use a complete biological filter. In all other cases, it is absolutely necessary to regularly replace at least once a week one-tenth of the water. At the same time, you must ensure that the temperature and chemical composition like nitrogenous compounds of the water remains the same as before the substitution.
A deviation from the norm is undesirable, since in case of temperature reduction it can lead to the occurrence of catarrhal diseases of the type Ichthyophthirius and even to the death of fish after the temperature increase.
The water hardness does not matter, the composition is neutral, slightly acidic (pH = 6.6-7.0). You need to monitor the active response very carefully.
Discus fish are from Brazilian waters and there are many types that can be interbred so it is recommended to contain only one type, However, it makes sense to start a herd of neon or zebrafish with the discus. These fish are very mobile and attract discus fry to their games, which helps to some extent to combat the hypodynamia that inevitably occurs in fish in the aquarium. This organization improves the assimilation processes in fry’s body. They grow faster. But when the fish reach the age of six months, other fish are removed from the aquarium.
Discus get used to any kind of food very quickly, especially the Bloodworm. However, this should not be allowed, as an unbalanced diet usually leads to sad consequences when spawning. You need to feed the fish with a variety of live food. It is better to give preference to the glassworm and Daphnia, the types of food that allows fish to move a lot in the process of hunting. You also need one hungry day a week. In the summer months it makes sense to give plant foods such as wolffia, spinach.
One of the most difficult problems is getting a good pair of discus. The peculiarity is that this type of fish is steamed at the beginning of puberty of choice. In addition, the usefulness of the producers depends largely on the care from adolescence in the right biochemical regime of water and feeding. Next, you need to skillfully select a group of fish for mating.
A couple separated from the pack jealously protects the chosen area-a bush of a large plant or a stone. Fish that have swum into their territory are driven away by fights in which the fish can be seriously injured. To avoid this, you need to discard the resulting pair from the general aquarium. The required number of discus mating pairs remains in the aquarium farm, the rest is removed. The producers are placed in the largest possible aquarium and begin to prepare them for spawning. During this time, the fish are fed intensively with a variety of live food, avoid Tubifex.
A sign of the spawning readiness of a pair can be above all the active cleaning of aquarium things, plant leaves, or decorations. The second sign of readiness can be seen as the trembling of the whole body-fish seem to throw off something that bothers them. Such a pair must be deposited in the spawning ground.
