Price of seed and stem discs are still quite expensive. Parent who is incubating the average price of 50-100 USD per pair. While the price of seed depends on its size. Seed size of a coin worth 4-5 USD.
Discus spawning
A. Prospective Parent Care
To be prepared in advance discus spawning tank with a capacity of 135 liters or panjnag measuring 80 cm, width 40 cm, and 40 cm high. Parent of the selected candidate must be healthy, well-organized side, the fin is not disabled, rounded body shape, natural movement no shooting or too slow and fairly prominent eyes are not bulging out. Discus fish would reach sexual maturity after the age of nine months. Female discus will reach maturity faster than the male gonads. At the age of 9 months had a female discus to produce eggs while the males can fertilize an egg at the age of 12-14 months. At the age of 9 months in the development of normal tesebut discus can reach the size of 5 inches. In the treatment of broodstock feeding can be done 3 times a day with silk worms or mosquito larvae.
B. Parent Selection
To be able to distinguish the sex of the discus, the parent of the selected candidate should come from the same place and maintained jointly. Male and female differences can be seen as follows: 1. Male - Upper lip more prominent than the lower lip - Has a nose that looks a bit crooked - Body color brighter and brighter - Have a larger body shape - Has a more rounded shape of the genital organs with a length of about 1.5 mm - Dorsal and anal fin is longer and tapered - More reflex movement 2. Female - Has a lip that is symmetrical, equal between the upper and lower lip - Has a nose that looks straight - Somewhat pale body color - Have a smaller body than the male - Has a genital organ that looks somewhat oval with blunt ends and 3 mm long reach - The dorsal and anal fins are rounded.
C. Preparation Spawning Aquarium which will be used in breeding should be placed in a closed room and dark. This is done by looking at the nature of the disc that requires a peaceful environment. Should the spawning tank is placed at a height of 120 cm from the floor. Preparation is the first in the discus breeder is a cleaning tank that will be used, moss-lichen attached to the glass aquarium scrubbed clean and disinfected by using a solution with low-dose PK. Location of the aquarium should be in the field of the flat, after that try to enter the water is clean water that is used instead of piped water. The height of water in the tank should be 3 cm below the tank lip, this is done to avoid spillage of water that moves somewhat keras.s Discus After the tank filled with water, insert the necessary tools such as a tool in the form of egg penempel paralon pipe measuring 4 inches. Tools penempel these eggs should be placed in the center tank. Setelahs penempel tool egg, insert the hose clean aerator with a given ballast. The next step is emmasang thermostat. To complement the breeding Discus, the red neon lights should be provided 10 watts. Parent who has grown up and in pairs included in the aquarium's pair by pair, in which the transfer is done 2 months before the parent-parent will be in production. Replacement of water is very important in preparation for breeding Discus as it would be helpful in improving appetite able to finalize a disc so that the egg faster. To replace the water tank should be done every single week by removing the water by ¼ section.
D. Spawning Processes
Parent discus will spawn it's time to find a place which he considers suitable place to spawn, in 3 to 10 days and then usually the marriage began to take place. It was marked by the commencement of the ritual dance. At the time the discus body color will look very intense, full of fluffy fins, and eyes look bright. On the sidelines of the dance if it has been found nesting places such as PVC pipes, flower pots, broken tiles, or ceramic. Parent discus will clean substrates are thoroughly clean. Once deemed clean enough, will discus pair began laying eggs. Symptoms can be seen with the release of genital organ and did a vertical movements along the substrate. After the first egg is laid., Discus males will fertilize it. This process is done continuously in turn, this entire process can last for several hours. The eggs are laid in yellow to reddish-colored substrate, the amounts vary. Parent females generally produce 150-400 eggs eggs.
E. Hatching Egg
After the spawning is over, the couple kept the discus will direct its eggs. They will be fanning the eggs with the pectoral fins to prevent any dirt or mold spores are attached. During guard the eggs until they hatch, the parent discus can eat their eggs. This will be done when they feel disturbed. If they instinctively decided to clean the eggs from the dirt they will lift the egg by eating it. Given these should in cultivating discs, eggs and caged substrate using woven wire so that the parent can not reach them but still can guard. Wire is left until the eggs hatch. The eggs hatch temperature required ranges from 300 C. Usually hatching in the aquarium can reach 50-95%. Discus eggs will hatch within 48-60 hours after fertilization. Following the development of egg to be a seed: 1. The first 40 hours
At this stage the eggs began to show its development from initially transparent yellow to red black spots began to appear right in the middle. Black spots are the spots on the eye, this indicates that the egg is fertilized properly. Eggs are not fertilized will remain transparent color which will then turn white and then rot. At this stage the eggs in critical condition because it is very susceptible to fungal attack. 2. The first 52-55 hours
At this stage the eggs hatch. Initially the egg shell will close, then larvae are fully developed will make subtle movements such as vibrations, penetrate the egg shell membrane. At this stage the larvae seen sticking out and moving with motile. These larvae remain attached to the substrate. 3. Fourth day
On the fourth day has seen progress on larval growth, they appear larger than the previous section attached to the substrate was living his head only. At this stage, though limited holding discus cage succeeded in removing the larvae either partially or entirely. Generally they would choose a place which was considered to be safer for these larvae. Foam sponge filters or glass in the rear tank to mesnjadi substrate to move the larvae. 4. Fifth day
On the fifth day, larval activity is increasing. Before the fifth day they stuck to the substrate in a neat position but now they seem to pile up and the occasional thrown from swimming for compounds with a chaotic motion. At this stage of parent discus will be busy collecting larvae and return it to their collection. 5. Sixth Day
At this stage larvae are strong enough to swim free. Starting with a two-tail began to experiment until the split second they were simultaneously flying from the substrate to the parent body. Parent discus readily welcome these larvae, and led him to remain in their sektar. This is when they begin to feed their first taste of mucus from the parent body.
F. Marriage Rules There are several lines of marriage that can be taken to get a quality disc such as:
1. Cross-breeding
Cross-breeding is often referred to interbreed. Usually used two different types of discs with their respective advantages. Body shape, style and color patterns, and other advantages. The first generation of this intercross will result in the discus with a diverse appearance. In the first generation has not achieved the stability of the gene. 2. Inbreeding Inbreeding is inbreeding. This means that discs from one seedling were mated with each other. However, after several generations of inbreeding should be stopped because it can cause a weakening of quality genes. This is indicated by the increasing percentage of defective puppies, weakening the immune system, slowing gonadal maturation, and kerdilnya growth. 3. Line-breeding Used to direct a gene expression in the desired direction so that the gene will get stronger. How dalah by mating the discus with an individual from one of the previous generation such as lane lines grandfather or father. 4. Outbreeding It is the methods used to strengthen the strain that has no risk ampan weaken as the inbreeding. The trick is to marry one type of strain with the same strain but from different paths such as paths cousin. In this way, genes in these strains will be maintained pure.
maintenance seed
After finishing move her children to a safer place, the parent will take care of with great affection. With gerakkannya to fan her son causing the dirt on his body to be removed. This movement can cool the seeds of the disc and provide the necessary oxygen. Discus seed can be left with their mother until the age of 14-20 days. After four days along with endless yolk discs are usually the children are strong enough to migrate. They will be clustered around the parent company. To feed provided by its parent in the form of mucus coming out of the parent body. Mucus in the whole body will thicken discs, this mucus is a highly nutritious food.
