不同生长阶段的龙鱼饲养方法

龙鱼（详细介绍）

龙龙鱼非常昂贵和美丽，具有很强的观赏价值，所以很多人都喜欢饲养龙鱼。你知道不同时期的龙鱼对环境、饮食和繁殖的重视程度不同吗？一、喂养幼龙鱼的要点龙鱼的生存需要弱酸到中性的水质，硬度需要软水。PH值6.5~7.5，DH值3~12。水温24~28℃。亚硝酸盐含量和氯含量最好为零。1.当一条新鱼进入鱼缸，新鱼刚被买回时，鱼缸中的空气泵应至少运行24小时，以彻底消除水中的氯。如果一直使用生物过滤器，最好使水达到6～7的PH值和25℃的水温。在鱼缸中加入少量盐（每5加仑或20升水约1或2茶匙盐），以降低真菌攻击的风险，使鱼健康并提高食欲。在条件允许的情况下，最好将新鱼的原缸中的水带回自己的缸中（如果原缸中水没有问题），最好将1/3的水收回，以利于新鱼对环境突变的不良反应。建议从小饲养龙鱼。2.日常管理：每周至少更换20%~30%的水，氨含量不超过百万分之0.1（mg/l）。不要突然改变温度和PH值，如突然变化会导致龙鱼突然死亡。每周测试PH值和其他有毒物质，以满足意外情况。换水时，小心避免龙鱼受到惊吓。另外，在饲养龙鱼的时候，一定要避免完全换成新的水，否则会对鱼造成伤害。如果你看到龙鱼的鳍和鳞片脱落，那是因为水分变化太多。你可以停止换水，它们会自然恢复；然而，改变的水量不应太小。太少会使鱼鳍不透明，眼球浑浊，从而导致鳃盖翻转。龙鱼（详细介绍）

2。成年期龙鱼的摄食点龙鱼的最佳生长期为2年左右，体长约45厘米，生长有明显减缓的趋势。过度喂养只会导致肥胖，因此成龙将无法在数量和质量上进食。基本的动物、昆虫和饲料食物可以一起喂养，只要它们能够满足营养均衡的前提。在成人时期很难保持旺盛的食欲。龙鱼对食物的生理需求显著减少。因此，除了进料周期的进一步调整外，以下几点也不应被忽视。1.成龙时期对水质的不同要求大多数红龙爱好者在这一阶段都会采用老式的喂水方式。此外，温度应进一步降低，一般为26~28度，冲浪的水流应进一步减少，或干脆在静水中升高，以促进头发颜色。由于换水周期过度延长，换水量减少，甚至几个月不进行换水，发红程度显著增强。由此产生的副作用是水体老化、硝酸盐含量过高和食欲下降。总的来说，成龙之后，随着喂食时间的增长，喂食过滤材料已经严重老化，藏污纳垢，甚至PH值下降到3.5左右。在鳞片、身体部位或每个鳍柄的骨头上都产生了肿瘤样的生长，身体局部腐烂导致的龙鱼精神萎靡不振，食欲明显下降。因为金龙系列没有老化和增色的问题，所以上述症状很少见。因此，我们应该准确地追求健康和发红。保持必要的换水周期和换水，分批消除老化的过滤材料，是保持旺盛食欲的前提。我不得不在这里谈谈换水方法。对于长期不换水、水体老化严重的水族馆，不宜采取大量换水措施。相反，需要少量换水，以逐步改善水质，并采取大量换水方法。即使水分变化超过1/5，也会造成PH值的大幅波动，从而引起龙鱼呕吐，损害胃，严重影响食欲，甚至导致长期拒绝进食。过滤材料的更换也应分小批量、逐步进行，以免造成水质过度动荡，必须给龙鱼一定的适应时间。为了减少水质过度动荡对龙鱼胃造成的损害，避免出现低食欲的情况。2.避免不必要的疾病。我相信大多数龙鱼爱好者都认为，成龙之后，龙鱼的抵抗力会显著增加，很难患上疾病。然而，在实际的喂养过程中发现，成龙之后，龙鱼更容易患病，原因很多，首先是生存空间的问题。随着龙鱼体长的不断增加，生存空间显著减少，活动量减少。其次，水老化的问题是The feeding method of arowana at different growth stages

arowana (detailed introduction)

arowana is very expensive and beautiful, and has strong ornamental value, so many people like to raise arowana. Do you know that arowana in different periods have different emphasis on environment, diet and breeding? Let's learn about it. 1、 The key points of feeding the young arowana are that the survival of the arowana requires weak acid to neutral water quality, and the hardness requires soft water. PH value is 6.5~7.5, DH value is 3~12. The water temperature is 24~28 ℃. The nitrite content and chlorine content should preferably be zero. 1. When a new fish enters the tank and the new fish is just bought back, the air pump in the fish tank should run for at least 24 hours to completely eliminate the chlorine in the water. If the biological filter is used all the time, it is better to make the water reach the PH value of 6~7 and the water temperature of 25 ℃. Add small salt (about 1 or 2 teaspoons of salt to every 5 gallons or 20 liters of water) in the fish tank to reduce the risk of fungal attack and make the fish healthy and improve its appetite. If conditions permit, it is better to take water from the original tank of the new fish back to its own tank (if there is no problem with the water in the original tank), and it is better to take back 1/3 of the water, so as to facilitate the adverse reaction of the new fish to the environmental mutation. It is recommended to raise the arowana from a young age. 2. Daily management: at least 20%~30% of water should be changed every week, and the ammonia content should not exceed 0.1 parts per million (mg/1). Do not make sudden changes in temperature and PH value, such as sudden changes will cause sudden death of arowana. Test the PH value and other toxic substances every week to meet the unexpected. When changing water, be careful to avoid the dragon fish being frightened. In addition, when raising arowana, we must avoid completely changing into new water, otherwise it will cause damage to the fish. If you see the fins and scales of arowana fall off, it is caused by too much water change. You can stop changing water and they will recover naturally; However, the amount of water changed should not be too small. Too little will make the fins opaque and the eyeball turbid, which will cause the gill cover to turn over. Dragon fish (detailed introduction)

2. Feeding points of dragon fish during adult period The best growth period of dragon fish is about 2 years, and its body length is about 45 cm, and its growth tends to slow down obviously. Excessive feeding will only lead to obesity, so Jackie Chan will not be able to feed in quantity and quality. Basic animal, insect and feed foods can be fed together, as long as they can meet the premise of balanced nutrition. It is difficult to maintain a strong appetite during the adult period. The physiological demand for food of arowana is significantly reduced. Therefore, in addition to further adjustment in the feeding cycle, the following points should not be ignored. 1. Different requirements for water quality in Jackie Chan period Most red dragon lovers adopt old water feeding at this stage. In addition, the temperature should be further reduced, generally 26~28 degrees, and the water flow for surfing should be further reduced, or simply raise in still water to promote hair color. Because the water change period is excessively prolonged, the water change volume is reduced, and even the water change is not carried out for several months, the redness is significantly enhanced. The resulting side effects are aging of the water body, excessive nitrate content, and low appetite. In general, after Jackie Chan, the feeding filter material has been seriously aged with the growth of feeding time, harboring filth, and even the PH has dropped to about 3.5. Tumor-like growths have been produced on the scales, parts of the body or the bones of each fin stalk, and the spirit of the arowana caused by the local decay of the body is depressed, and the appetite is significantly reduced. Because there is no problem of aging and color enhancement in Jinlong series, the above symptoms are rare. So we should be precise in the pursuit of health and redness. Maintaining the necessary water change cycle and water change, and eliminating aging filter materials in batches are the prerequisite for maintaining a strong appetite. I have to talk about the water change method here. For aquariums that do not change water for a long time and the water body is seriously aging, it is not appropriate to take a large amount of water change measures. Instead, it is necessary to change water for a small number of times to gradually improve the water quality, and take a large amount of water change methods. Even if the water change exceeds 1/5, it will cause a large fluctuation in PH, which will cause arowana vomiting, damage the stomach, seriously affect appetite, and even cause long-term refusal to eat. The replacement of filter materials should also be carried out in a small number of batches and gradually, so as not to cause excessive water quality turbulence, and the arowana must be given a certain adaptation time. In order to reduce the damage to the stomach of arowana caused by excessive water quality turbulence and avoid the occurrence of low appetite. 2. Avoid unnecessary diseases. I believe that most arowana lovers believe that after Jackie Chan, the resistance of the arowana will increase significantly and it is difficult to suffer from disease. However, in the actual feeding process, it was found that after Jackie Chan, the arowana was more vulnerable to disease, for many reasons, first of all, the problem of living space. With the continuous increase of the body length of the arowana, the living space is significantly reduced, and the amount of activity decreases. Secondly, the problem of water aging is that the chances of getting sick are increased due to the reduction of water quality conditions. Practice has proved that the young dragon's ability to adapt to the new environment is much stronger than Jackie Chan's. Of course, the problem of disease involves the whole breeding process of arowana. The low appetite of arowana in the sick period is an inevitable problem. Do a good job in disinfection of live bait to avoid carrying bacteria into the tank, and avoid visceral inflammation and infection caused by the breeding of bacteria in the water body that is too old, resulting in eye depression, body surface congestion, abdominal swelling. For shrimps and other foods with hard shells, the shrimp sword must be removed to avoid visceral damage, etc. Only by avoiding unnecessary diseases to the greatest extent and maintaining a healthy physique, can the arowana grow healthily with a strong appetite. The breeding of arowana needs to be very meticulous, and it also needs sufficient experience to raise it well. If the breeding experience is insufficient, we should always observe the status of arowana, and deal with any situation in a timely manner
