Dragon fish growth habit of arowana mixer and reproduction method

Introduction

Aonaurus, also known as Aragona beads, silver band fish and silver boat fish, silver saury, is called AROWANA (local Chinese read "Yalova") in the place of origin.The meaning of the arowana is "SCLEROPAGES", which is the meaning of the tongue, choking -like, and because of its huge shape, the trunk is covered with a huge, neatly arranged, shining light scales, large mouths, lips corners of the lipsThere are two tentacles. When swimming, the expression is leisurely, like the "dragon" in mythology, so it is named "arowana".It still retains the characteristics of ancient times, known as "fish living fossils", which has great breeding and ornamental value.

Arowana

1. Red Dragon

Also called Hong Jinlong.This fish is protected by the Washington Convention as an endangered species.Its juvenile has a lighter body color, red red, and small scales.However, the body of adult fish is huge, and the edge of the cheeks shows strong dark red, the tongue is the same, and the edge of the large scales and the strong red patterns of each fin and the golden scales are shining.It is a large fish with great ornamental value.

2. Chili Red Dragon

There are two types: the background color of the first scale is blue, and the second head has green fish Skin.The body is covered with thick -frame scales, dark red gills, and a larger fin and tail fin.The juvenile of this fish can be longer body, large eyes, diamond fins, pointed and protruding heads, and red fins, especially its pectoral fins, which are easily confirmed.The diameter of its large eyes is usually equivalent to the distance between the eyes and the tip of the mouth.The scales have a touch of green, yellow or orange.However, the fastest color of this fish will have to wait for one and a half years to appear. If it is slow, it will have to wait for four years or longer.

3, blood red dragon

The body is 15 cm long.The body of the blood -red dragon adult fish is mainly covered by a thin -frame scales, and the gill cover is also red.This fish has a red fin, but the body is relatively slender.Different from the Pepper red dragon, the color of the blood red dragon will soon appear after a year. Its juvenile body is relatively longer than the Pepper red dragon tongs, and the fins and eyes are relatively small.The fins of the blood red dragon are the same red.The difference is that its caudal fin is round, and the head is no more than the Pepper red dragon juveniles. The scales are slightly light green and pink color.

4. Orange Red Dragon

Generally, the body is as long as 90 cm. The gill cover of this fish is usually orange -red scales.The fins of some orange dragons are orange -red, and some of the inferior orange -red dragons are even yellow. The unique is that the head of the juvenile is relatively round.It is a member of the Antarian family. It has the physique and strong adaptability to the environment. It is a relatively easy to raise ornamental fish. The arowana is a high -end ornamental fish variety in the market. Therefore, the price is high.Love also makes it a darling in the fish family.

5. Banjia Red Dragon

Banjia Red Dragon was once considered to be an individual that is artificially hybridized, namely the product of the red dragon and the blue dragon.But in fact, Banjia Red Dragon is a native species.Of course, when artificial reproduction is carried out, some may be mixed with the blood of the Red Dragon, which makes the color of the rear three fin more red.The latter three fins of Banjia Red Dragon fish are red, which is not easy to distinguish from the red dragon's juvenile.But after it grows to adult fish, Ban Jia Red Dragon will not make color, so this kind of arowana is crowned with No. 1 red dragon or No. 2 red dragon.The name of this crown has continued to this day, but it cannot be confused with the Red Dragon.During the juvenile period, Banjiahonglong was more round and full of body. The scales were not shiny, and the layers were not strong.When the fishing period, the head shape is relatively round, the rear three fins are orange -red, the scales and gill cover will not make color. The improved Banjia Red Dragon has individual individual gill lids that will have light yellow.

6. Qinglong

Body is shorter than other Asian arowana.The scales blue side line is significantly developed.The most valuable purple marks are presented with scales.Some green dragon scales are produced in Thailand, Myanmar, Dongpuzhai, Vietnam, Malaysia, and Indonesia. Some are transparent and some are opaque.Its side line is even more conspicuous in its gray -green scales.On the upper part of Qinglong's body, there will be a faint blue or purple.The head of adults is also round and smaller.Can be reproduced artificially.

Dragon fish growth habit

In the natural world, arowana is a freshwater fish living in the upper waters with weak acidity. Therefore, in the aquarium, arowana can survive between the water temperature between 20-30 degrees Celsius?--- 28 degrees Celsius is the best.The pH is between 6.5 and 7.5.The arowana is very sensitive, and the ability to change the outside world is very strong. The excessive frequency or too much change will cause the arowana to be frightened, which is likely to cause illness. Therefore, it is important to keep the dragon.The stability of fish grows.

Aravian breeding method

1. Water quality mediation

Chlorine gas: Quiet for 48 hours or dried for 24 hours.If you urgently use it, you can add 0.63 grams of soda per 100 kg of water, also called sea wave (ie sodium sulfate) and stir and dissolve.

Chloride: This ingredient is generally not mentioned, and it is easy to be ignored. This is also one of the key issues of raising fish.There are high concentrations of soluble organic substances in some areas. If the water plant is added directly at this time, it can be combined with these organic substances to form some carcinogens, which will harm the human body.Therefore, the water plant adds chlorine gas and ammonia at the same time in the water. These two substances can be combined into a new material called chloride, and the chlorine is not combined with organic matter in the water. ThereforeIn the water.This requires a good nitrogen cycle, which can be removed with biological filtration.Here I want to remind friends who just bought a new cylinder, why many friends are prone to dead fish when changing a new cylinder, because the biological decomposition and filtration in the new cylinder is not formed.The best way to love fish is to remove the ammonia in the water with Zlaolin.

The survival of arowana requires weak acidity to neutral water quality, and hardness requires soft water.The pH value is between 6.5-7.5 and the DH value is 3-12.Water temperature is 24-28 degrees Celsius.Nitrite content and chlorine content are best zero.Pay attention to sodium phosphate: The degree of pH value every day should not exceed 0.5-1ph, and the violent oscillation will cause the death of arowana.Tip: Appropriate explosion and oxygen can play a stable pH value.

Simply nitrogen cycle: As long as the fish tank is put in the fish, they will discharge ammonia and other waste into the water. The ammonia concentration in the water will increase. Of course, the beneficial microorganisms (digestive bacteria) in the water will decompose ammonia and turn it into sub -sub -sub -Asia.The concentration of nitrate (toxic) is then converted into nitrate (non -toxic) nitrate nitrate (so it is necessary to change water to change water).Note: The formation of digestive bacteria takes about 1 week, and it takes about 1 week to transform harmful substances. The change from ammonia to nitrite to nitrate is called nitrogen cycle.To make a new cylinder reach a good nitrogen cycle state, it takes about 2-3 weeks to do not be irritable.

2. fish tank

Because arowana is a large fish, the fish tank is at least 1.5 meters long, 0.5 meters wide, and 0.7 meters high.The fish tank must be covered. The arowana belongs to the fish that swim on the upper layer and likes jumping to avoid suffocation and death when no one jumps.

3. Light time

Red arowana needs a lot of light, and it is best to reach 4 hours a day.Other arowana can also reach 8 hours of light.Some fish farming lovers, such as red fish, like to use red light to illuminate red arowana, so as to achieve better results.The best light of the arowana is the daylight of the day. Long -term use of Lights will cover the back of the Dark Arols.

4. Filter method

The arowana juvenue is too large, so it is not suitable for raising in the waterweed box.The problem of filtering the fish tank is more prominent.Filtering systems suitable for arowana breeding mainly include upper filters, external filters, upper pumping sand layer filters, and overflow filters.

5. Feed

When eating food, the arowana will hit a certain angle in the tank to cause injuries. It is best to eat it in the middle of the fish tank when feeding.The arowana belongs to meat -type animals. Most of the recipes of arowana are frogs, loach, crickets, goldfish, grasshopper, shrimp, etc.There is a problem of adding color when feeding. For example, red dragons, feeding red arrows or shrimp plays a certain role in adding color to the Red Dragon, because red arrows and shrimp body contain red color.

Arowana hybrid method

1. Choose suitable arowana with fish

If you want to successfully carry out the alerthon, you must first choose the appropriate fish. Not every kind of fish is suitable for mixing with arowana. For example, the starlona mixer is very difficult.So, what fish is mixed with arowana?Among the arowana players, the common fish species mixed with arowana are: arowana, tiger fish, flying phoenix, colorful, etc.The arowana belongs to the upper fish and has a strong sense of territoriality. Therefore, when choosing a fish mixed with the arowana, try to avoid choosing the upper fish.

After determining the mixer fish, consider the size of the mixer fish.If the mixer fish is small and the gap with the body of the arowana is too large, it will be invaded by the arowana, resulting in the failure of the hybrid.Therefore, when choosing a hybrid fish, it is best to choose a fish that is similar to arowana.

2. Fully consider the hybrid environment

The arowana belongs to large fish and grows fast. It will grow to 45-50 cm in about two years. In addition, ordinary fish friends generally cannot buy the fish tank every two years. ThereforeThe requirements are stricter.Therefore, in the mixer, we must fully consider whether the specifications of the dragon cylinder can be afforded, and the density of the mixed -care fish must not be too large.

3. Calmly face mixed -nourishing fish and only fight

When choosing a arowana mixer, the arowana and other mixed -breeding fish will inevitably fight.When the fish appears only, the arowana and other fish are only competing for the border. If it is constant and when the fight is, it will be separated, and the Fighting time will be extended artificially.Therefore, when the arowana and other fish only fight, unless they are very serious, try to avoid isolation.Before the mixed care, you can put small fish and small shrimp in the tank to feed the arowana to attract the attention of arowana.In addition, the arowana mixed care must have a powerful and effective filtering system, which can ensure water quality, avoid injuries and infection after Fighting arowanons and other fish, and then cause other diseases.

4. Form a good hybrid habit

When the arowana mixed care, the density of the fish in the tank increases, the fish only eats, and the excrement is more. After the Battle, the injury will be injured. Therefore, the stable water quality is very important.Keep water quality during mixing, fixed water replacement time, temperature, water volume and other factors.

5. Correctly face diseases that occur during mixed care

Dragon fish mixed nursing often appears in scales, small white spots on fins, etc., mainly caused by fish only Fighting.After the fish only occurs, you must use chemicals with caution. You must see the disease clearly. Try to use the third three -like when you can use the old three instead of rushing to apply the medicine.

Dragon breeding method

1. Natural pairing: Mix 5-6 arowana together and let them cultivate feelings by themselves. This is the ideal form of natural pairing.If you start mixing from the juvenile, the chance of success is relatively high.

2. Artificial pairing: In the large water tank, place the male and female arowana on both sides of the sink and set the partition in the middle.The acidity and alkali changes cause arowana disease.
