蝴蝶尾金鱼的繁殖。因为它们的大蝴蝶尾巴非常漂亮，所以深受人们的喜爱。在饲养这种特殊的物种时，我们应该注意什么？1、 蝶尾金鱼的选择应色泽鲜艳、健康、丰满、饱满，尾部形状匀称。尾鳍应分为四段开放，臀鳍应平衡并具有特征。如果出现以下情况，请不要选择：1。游泳时，尾鳍不能左右均匀摆动；2.尾鳍基部受伤或有受伤的折痕；3.尾鳍太大，无法超过身体部位，鱼生长缓慢；尾鳍未完全张开，有粘连；4、有其他身体缺陷或眼睛脱落2、建议产卵池雌雄蝶尾比例为1:2，水温在15℃左右。我们先用金鱼藻为鱼形成一个直径6厘米的圆形鱼窝，先用亚甲蓝浸泡2到3分钟，然后用1毫克/升的二氧化氯或1毫克/公升的阿维菌素浸泡2到5分钟，然后放在产卵池中。一般情况下，第一天下午放新鱼窝，第二天中午取出，第三天早上再放新的鱼窝。3、 孵化水温应与产卵时的水温一致。通常，孵化5到6天后，膜就会出现。在最初的2到3天，我们可以仔细观察，如果鱼卵是白色的，则是未受精卵，如果鱼蛋是透明的，则为受精卵。四到五天后，会观察到黑点，即幼虫的眼睛。4、 至于摄食，小鱼通常在鱼窝放入孵化池后6至7天从膜中出来。再过两天，我们可以用蛋黄等食物喂养它们。建议使用10个鸡蛋到40公斤的水，并使用喷雾器将其均匀地喷洒在鱼缸中，任何一点都不会泄漏。此时，小鱼虽然会游泳，但游泳能力相对较弱，因此喂食是必要的。此时，鱼很小，死后不会被看见。它通常被称为“凸起”或“熔化”。喂蛋黄3天以上后，就可以把小红虫放进鱼缸了。小红虫是小鱼很好的营养食物。它们吃完后会很快长大。如果食物充足，20天后它们会长到2到3厘米。此时，可以选择一些好的鱼苗进行正式养殖
The breeding of butterfly tail goldfish. Because their large butterfly tails are very beautiful, they are deeply loved by people. What should we pay attention to when raising such special species? 1、 The selection of butterfly tail goldfish should be bright in color, healthy, plump and plump, with symmetrical tail shape. The tail fin should be open in four sections, and the hip fin should be balanced and characterized. If there are the following situations, do not choose: 1. When swimming, the tail fin cannot swing evenly from side to side; 2. The base of the caudal fin is injured or has an injured fold mark; 3. The tail fin is too large to exceed the body part, and the fish grows slowly; The caudal fin is not fully opened and has adhesion; 4. Having other physical defects or eyes falling off. 2、 It is suggested that the ratio of male and female butterfly tails in the spawning tank should be 1:2, and the water temperature should be around 15 ℃. We first use goldfish algae to form a round fish nest with a diameter of 6cm for the fish, first soak it in methylene blue for 2 to 3 minutes, then soak it in 1 mg/L chlorine dioxide or 1 mg/L avermectin for 2 to 3 minutes, and then put it in the spawning tank. Generally, the new fish nest is put in the afternoon of the first day, taken out at noon of the second day, and then put the new fish nest in the morning of the third day. 3、 The water temperature for hatching should be consistent with the water temperature at the time of spawning. Usually, the membrane will emerge after 5 to 6 days of hatching. In the first 2 to 3 days, we can carefully observe that if the fish egg is white, it is unfertilized egg, and if the fish egg is transparent, it is fertilized egg. Four to five days later, black spots will be observed, that is, the eyes of the larvae. 4、 As for feeding, the small fish usually come out of the membrane 6 to 7 days after the fish nest is put into the incubation pool. In another 2 days, we can feed them with food such as egg yolk. It is recommended to use 10 eggs to 40 kg of water, and use a spray to evenly spray it in the fish tank, without leaking at any point. At this time, although the small fish can swim, its swimming ability is relatively weak, so feeding is necessary. At this time, the fish is very small and will not be seen after death. It is commonly known as "raised" or "melted". After feeding the egg yolk for more than 3 days, you can put small red worms into the fish tank. Small red worms are a good nutritional food for small fish. They will grow quickly after eating. If the food is sufficient, they will grow to 2 to 3 cm after 20 days. At this time, some good fish fry can be selected for formal breeding
