如何使金鱼更漂亮

金鱼（细节）

如果你想让金鱼更漂亮，养鱼的水非常重要。如果你想让金鱼在人工培育后变得美丽，你需要主人的精心饲养。1、 温度金鱼是一种温度变化的动物。刚孵出的金鱼幼虫最适合生长的水温为22℃~24℃，变色最快的温度为25℃~30℃。需要注意的是，水温的变化不能超过5℃，否则金鱼会感冒。水深不能超过50厘米，如果超过50厘米的话，夏天会有热分层，水温不一致，变色速度会变慢。如果水温长时间超过30℃，金鱼不仅会失去光泽，还容易患上烫尾病。2、 水质主要指水的pH值和硬度。金鱼变色期的最适pH值为7.5～8.5。过多的碱或过多的酸会刺激鳃腺，阻碍呼吸和血液循环，并使金鱼的颜色变暗。水体的最佳硬度在4mg/L至10mg/L之间。如果低于3毫克/升或高于15毫克/升，将危及金鱼的生存。水中溶解氧的量对金鱼的颜色变化也非常重要。金鱼要求水中溶解氧的量大于3mg/L。溶解氧含量越高，鱼的新陈代谢越旺盛，饲料利用率越高，变色速度越快。如果降至1毫克/升，金鱼会漂浮，变色缓慢，没有光泽。如果长期生活在溶解氧过多的室外鱼塘中，金鱼会生气，失去观赏价值。用来喂养金鱼的水通常是井水、河水、湖水和自来水（脱氯）。这些水域富含微量元素，有利于金鱼体表色素细胞的分裂和增加。当金鱼在清水中饲养时，鱼苗会很快变色，但变色后的金鱼会很淡但不亮。如果金鱼在淡水和绿水中交替饲养，颜色变化会更快，颜色也会更鲜艳。这一交替期通常约为30天。3、 光照直接影响鱼苗的颜色变化。虽然室内水族馆的鱼苗四面都暴露在光线下，但光线较弱，这对金鱼的颜色变化不利。因此，应使用照明设备。一般的水族馆可以安装40-60瓦的荧光灯，每天打开6-10小时。在室外的金鱼池中，东西两侧应遮挡阳光，避免阳光直射，防止金鱼变白。4、 油炸食品有很多，但浮游生物是最好的。刚孵出的金鱼的蛋黄在2-3天后消失。你可以在7到8天后喂一些煮熟的蛋黄、轮虫，体长超过6厘米时可以喂水蚤、红虫、水虫等浮游动物。实践证明，变色的最佳诱饵是小龙虾：血红虫。当添加一些血粉、昆虫粉和各种维生素时，红色、金色和蓝色金鱼的颜色变化非常快，而且闪闪发光。在喂食过程中，他们的食物摄入量应控制在60%至80%饱腹。如果低于40%或超过80%，喂养时间长，会造成营养失衡，从而导致体表粘液分泌功能紊乱，金鱼会出现发黑和生病的现象

How to make goldfish more beautiful

Goldfish (details)

If you want goldfish to be more beautiful, the water for fish breeding is very important. If you want goldfish to become beautiful after artificial cultivation, you need the owner's careful breeding. 1、 The temperature goldfish is a temperature-changing animal. The most suitable water temperature for the growth of newly hatched goldfish larvae is 22 ℃~24 ℃, and the fastest temperature for color change is 25 ℃~30 ℃. It should be noted that the change of water temperature should not exceed 5 ℃, otherwise the goldfish will catch a cold. The water depth should not exceed 50 cm. If the water depth exceeds 50 cm, there will be thermal stratification in summer, and the water temperature will be inconsistent, and the discoloration speed will slow down. If the water temperature exceeds 30 ℃ for a long time, the goldfish will not only lose its luster, but also easily suffer from scalding tail disease. 2、 Water quality mainly refers to the pH and hardness of the water. The optimum pH value of goldfish at the discoloration stage is 7.5~8.5. Over-alkali or over-acid will stimulate gill glands, hinder respiration and blood circulation, and darken the color of goldfish. The best hardness of water body is between 4 mg/L and 10 mg/L. If it is lower than 3 mg/L or higher than 15 mg/L, it will endanger the survival of goldfish. The amount of dissolved oxygen in water is also very important for the color change of goldfish. Goldfish require that the amount of dissolved oxygen in water be more than 3 mg/L. The higher the amount of dissolved oxygen, the more vigorous the metabolism of fish, the higher the feed utilization rate, and the faster the color change speed. If it drops to 1 mg/L, the goldfish will float, change color slowly and have no luster. If you live in an outdoor fishpond with excessive dissolved oxygen for a long time, goldfish will get angry and lose their ornamental value. The water used to feed goldfish is usually well water, river water, lake water and tap water (dechlorinated). These waters are rich in trace elements, which are conducive to the division and increase of pigment cells on the body surface of goldfish. When goldfish are raised in clean water, the fry will change color quickly, but the goldfish after color change will be light but not bright. If the goldfish are raised in fresh water and green water alternately, the color change will be faster and the color will be bright. This alternate period is generally about 30 days. 3、 Light and light directly affect the color change of fish fry. Although the fish fry in the indoor aquarium are exposed to light on all sides, the light is weak, which is unfavorable to the color change of goldfish. Therefore, lighting equipment should be used. The general aquarium can be installed with 40-60 watt fluorescent lamps, which are turned on for 6-10 hours every day. In the outdoor goldfish pond, the east and west sides should cover the sun to avoid direct sunlight and prevent the goldfish from turning white. 4、 There are many edible food for fry, but plankton is the best. The egg yolk of newly hatched goldfish disappears after 2 to 3 days. You can feed some cooked egg yolks, rotifers after 7 to 8 days, and zooplankton such as water fleas, red worms, water worms, etc. can be fed when the body length is more than 6 cm. Practice has proved that the best bait for color change is the crayfish: blood red worm. When adding some blood powder, insect powder and various vitamins, the red, gold and blue goldfish change color very quickly and shine. In the feeding process, their food intake should be controlled at 60% to 80% full. If it is less than 40% or more than 80%, and the feeding time is long, it will cause nutritional imbalance, which will lead to the dysfunction of mucous secretion on the body surface, and the goldfish will have the phenomenon of blackening and illness
