喂养幼金鱼的注意事项

金鱼（详情）幼金鱼正处于生长发育的旺盛时期。此时，幼鱼非常娇嫩。喂食不当会导致疾病或死亡。在这个时期，如果你能掌握它的生活习惯和规律，加强对它的维护和管理，即使把它放在一个小容器里，也能保持它的强壮，从而保持它的明亮和活泼。一两周后，金鱼苗可以长到1厘米长。此时可以投喂鱼虫或适口的人工饵料，当幼鱼长到1-2厘米长时，肉眼已经可以分辨出单、双或不完整的尾鳍。第一个选择应该在适当的时候根据尾鳍的形状进行，留下双尾鳍，去除单尾和剩余的双尾。随着鱼体的不断生长，背鳍也已经与龙背和残留背明确区分，需要第二种选择。在背鳍科中，选择背鳍规则且鳍完整的科；在没有背鳍的蛋科中，选择背部平坦光滑、无残留鳍和无突起的蛋科，消除有残留鳍和突起的蛋。今后要根据物种的特点，继续分阶段选择尾鳍、背鳍、体型、眼睛、鳞片、水泡、鞍部、高头、虎头和颜色，并为每次选择调整放养密度。饲养3-4个月后，幼鱼可以进行第二次筛选。此时，可以看到臀鳍。因为每个物种的筛选标准不同，所以你应该尽量选择具有该物种特征的幼鱼。尽量选择身体强壮、体短、左右对称的幼鱼。幼金鱼每天应喂食2-3次，每次喂食的量应在1-2小时内消耗掉。饲养时间应该在春季和夏季的早期，通常在早上6-7点左右。深秋和冬季的饲养时间可以稍晚，通常在上午7-8点左右。在寒冷的冬季，饲养时间甚至可以推迟到晚上10点左右。饲养金鱼最重要的是水质，保持水的清洁，调节水温，增加水中的氧气，从而刺激金鱼的生长发育。饲养者饲养金鱼最重要的原则是“先养水”。有了良好的水质和环境，金鱼自然会健康生长

Precautions for feeding young goldfish

Goldfish (details) The young goldfish is in a vigorous period of growth and development. At this time, the young fish is very delicate. A little improper feeding will cause illness or death. In this period, if you can master its living habits and laws, and strengthen its maintenance and management, you can keep it strong even if it is kept in a small container, so as to keep it bright and lively. After a week or two, goldfish fry can grow to 1 cm in length. At this time, fish and insects or palatable artificial bait can be fed. When the young fish grow to 1-2 cm long, the naked eye can already distinguish the single, double or incomplete tail fin. The first selection should be made according to the shape of the tail fin at the right time, leaving the double tail fin and removing the single tail and the residual double tail. With the continuous growth of the fish body, the dorsal fin has also been clearly distinguished from the dragon back and the residual back, and the second choice is needed. Among the families with dorsal fins, those with regular dorsal fins and intact fins are selected; Among the egg families without dorsal fins, select those with flat and smooth back, no residual fins and no protrusions, and eliminate those with residual back and protrusions. In the future, according to the characteristics of the species, we should continue to select the tail fin, dorsal fin, body shape, eye, scale, blister, pommel, high head, tiger head and color in stages, and adjust the stocking density for each selection. After 3-4 months of feeding, the juvenile fish can be screened for the second time. At this time, the gluteal fin can be seen. Because the screening criteria for each species are different, you should try to select the juvenile fish with the characteristics of this species. Try to choose young fish with strong body, short body and symmetrical left and right. The young goldfish should be fed 2-3 times a day, and the amount of each feeding should be consumed within 1-2 hours. The feeding time should be early in spring and summer, generally around 6-7 am. The feeding time in late autumn and winter can be a little later, generally around 7-8 am. In cold winter season, the feeding time can even be delayed around 10 pm. The most important thing to raise goldfish is water quality, keeping the water clean, regulating the water temperature, increasing the oxygen in the water, thus stimulating the growth and development of goldfish. The most important principle for the breeder to raise goldfish is "raise water first". With good water quality and environment, goldfish will naturally grow healthily
