The so-called standard body shape is that all parts are well proportioned, not too fat or too thin, or even deformed or hunched. To have a beautiful figure, the environment, bait food store and wave-lifter are necessary conditions.
The size of the environment (aquarium) directly affects the growth and body development of arowana; When the environmental space is small, the growing arowana will be short, chubby or hunchbacked, so it is necessary to provide the environmental size according to the size of arowana, which is basically three times the length of arowana as the basic length of the fish tank.
In terms of bait food, it is necessary to have a balanced nutrition. In addition to the staple fish and shrimp, it can also be matched with other fish foods to avoid arowana being biased towards food stores. The amount of bait should not be too much, but should be controlled well, usually twice a day, once in the morning and once in the evening. The quantity control is based on the maximum consumption of arowana (that is, the amount of food that you don't want to eat), which is reduced by 25%, which is the best fear of eating. The advantage of controlling food intake is that it can avoid the overweight and slow response of arowana, make arowana lively and increase its affinity with its owner. The most important thing is to judge the health status of arowana. For example, the average food intake is five shrimps and two small fish at a time, but it is less than a few days in a row, and it is decreasing day by day, so it can be concluded that arowana has a condition!
The reason may be man-made shock, water quality change or disease infection, which should be dealt with as soon as possible.
Wave elevator is to increase the speed of dissolved oxygen and water flow. In nature, arowana lives in a wide river, and it has to shuttle through the river to find food, with sufficient swimming. However, in the limited space of the aquarium, under the careful care of the owner, it is easy to get fat due to too little swimming and eating nutrition, resulting in physical weakness and weakened resistance. Adding a wave-lifting device can make up for the shortcomings of the aquarium and promote the physical strength and resistance of arowana.
(2) Beard
Beard is an extension of arowana's position. If it is broken, short, stiff and crooked, its power will be greatly reduced. How to cultivate a straight beard, we must first prepare a space suitable for activities and prevent the beard from breaking and deforming.
In an environment with insufficient space, arowana will constantly rub the cylinder wall with the tip of its jaw because it is too narrow, which will make the beard grow shady, and will make the tip of its jaw form sarcoma under long-term friction, which will affect the appearance.
Attention should be paid to prevent beard injury:
1, don't decorate. Such as rockery and stone landscaping.
2. Don't feed in the corner of the aquarium when you are afraid of eating, but in the middle of the aquarium.
3. Don't beat the aquarium to scare the arowana.
4. The upper part of the aquarium is covered with glass, and the right angle is rounded.
All the above four situations can prevent arowana from being hurt when chasing food or jumping.
If the beard is injured, it will be broken and restored, depending on the age of the fish. Usually, young arowana is strong in restoring growth, while big arowana is slow or even stops growing. There are two kinds of broken whiskers: first, it is difficult to recover because the roots are cut off together, even the young dragons are difficult to grow again. Second, if the root is not injured, it can be seen as broken but not broken. It is necessary to remove the broken beard to avoid healing and deformation in the future.
If the neat root is broken, or it is not long after breaking, the growth can be promoted by means of needles, which are as follows:
1, prepare the sterilized fine needle first.
2. Anesthetize the arowana.
3. Put the anesthetized Arowana on a plastic cloth.
4. Stab the root of arowana beard with a fine needle until it bleeds and swells.
5. Put it back in the fish box, add an air pump to pump it up and wait for it to regain consciousness, and add an appropriate amount of antibiotics.
This acupuncture operation, it is best to invite experts, or have advanced experience in arowana surgery.
(3) Eyes
Arowana's eyes should be flat and bright to be beautiful, but most arowana raised in aquariums have the phenomenon of eyes looking down. The reason for the downward gaze is the accumulation of fat in the eyes, and it is a natural physiological phenomenon that the arowana is attracted by the flat environment of the outside world for a long time because it is looking for sunken live bait such as fish and shrimp and the aquarium is in transparent body, and the position of the aquarium is high. The way to avoid arowana's eyes looking down is as follows:
1, afraid to eat floating bait (dry bait), if it is live bait, first stun it and quantitatively avoid eating.
2. At night or when not watching arowana, the lighting equipment lights up, and the aquarium is surrounded by black cloth or opaque materials.
If the eyes look down slightly at the beginning, they can be covered with black cloth all day long, and the phenomenon of looking down can be corrected in one to three months, but the effect is not loud, and it is easy to hurt the fisheye. Readers should not try easily.
Downward looking is not a disease, but a natural physiological reaction, and the owner need not worry too much. The most important thing is the love and emotional contact with the reared arowana.
(4) Gills
The normal gill cover should be smooth and smooth, without contusion, wrinkles or whiskers. To increase the beauty of gills, we must pay attention to the following nine points:
Attention should be paid to prevent beard injury:
1, don't decorate. Such as rockeries and landscaping stones.
2. Keep the temperature constant. When the temperature is too high, the epidermis of gill cover and head will produce wrinkles, and the temperature difference between hot and cold will be too large, which will cause gill turning.
3, change the water regularly, don't change the water too often, basically change about one-third in 8 days (unless you want Ailong to change the water frequently) to maintain the best water quality.
4, improve the dissolved air in water.
If the gill is bruised, appropriate antibiotics or special fish medicine should be put in to prevent bacterial infection of the wound.
(5) Scales
The giant scales of arowana are one of the most attractive items. Normal scales should be smooth and orderly arranged, and they should be avoided from being damaged or falling off. The method of prevention is:
1, don't decorate decorations, such as rockeries and landscaping stones.
2. Pay attention to whether the arowana is infected by parasites or white spot disease, because the arowana will rub the utensils to stop itching.
3. Change the water regularly to maintain the best water quality.
4. Don't scare the arowana.
5, catch arowana, don't use nets, use plastic fish bags.
If the scales fall, they can grow and recover after 3~5 weeks. Pay attention to water quality in the growth stage, and prevent bacterial infection, so as to avoid scaling deformation due to friction. In case the scales are deformed, the arowana can be stunned by anesthesia, and the deformed scales can be pulled out for re-growth.
(6) Fin
The fins of arowana are like human hands and feet. If each fin is deformed, it will affect the swimming posture and overall beauty of arowana. Beautiful fins must be smoothly developed, with straight stems and intact fin membranes.
In order to make the fins of arowana develop smoothly, we should start from the juvenile stage. First, the feeding space should not be too large, because the young arowana is too large, and it is easy to be frightened and stabbed because of its unstable personality, and the fins will shrink when swimming, which will affect the development of the fins in the future. It should be in a small environment, that is, young fish will not be frightened by people in a small environment. Moreover, swimming in a small environment requires turning from time to time, and the fins will naturally unfold. When the baby dragon grows up and has a stable personality, it will move into a larger aquarium.
Precautions to avoid damage to each fin:
1, don't decorate, such as rockery, stone landscaping, etc.
2. Young dragons should not be mixed with other kinds of fry or raised with multiple fry.
3. Young dragons should be fished with the finest mesh, but arowana over 15 cm should not be fished with a net, and plastic fish bags should be used.
If the fin injury is a single stem fracture and the fin membrane is connected, it can be torn off from the lower half of the stem fracture along the fin membrane by hand to wait for it to grow again. In case of multi-branch fracture, it is necessary to trim it with scissors under anesthesia.
Treatment should be done immediately if the fin stem bone is broken, especially the caudal fin, because the caudal fin stem is broken, and the fish moves with the caudal fin when swimming, and the broken part will not be fully recovered; It is still possible for other fins to heal naturally, but after healing, there will be more than skew or deformity.
The trimmed fin is more complete after growth, but it will be a little wavy, but it will be fine.
It is best to invite experts or have experience in arowana surgery to perform anesthesia pruning surgery.
Arowana breeding
The beauty of a arowana is innate, but the cultivation of acquired fish is also very important, because the innate condition is a kind of potential. If it is not taken care of by acquired fish, it will be a pity and a heartbreaking thing to urge it to exert its potential and show its beauty. In order for arowana to show its beauty, we must pay attention to the above points.
