金鱼在水面吐泡泡怎么回事

　　金鱼在水面吐泡泡有可能是水中的氧气含量低，是饲养密度大或者水中腐败的物质过多导致的，饲养者可以根据实际情况及时换水或打氧；也有可能是因为金鱼消化不良，通过自身的调节来排出气体，这种情况可以停止喂食3天，等待金鱼自行消化；还有可能是水温过低或者水质太差，也会导致金鱼浮在水面上吐泡泡。可以尽快提高水温到25度左右，且及时换水，保持好鱼缸内的水质。

　　金鱼的形态特征：

　　金鱼在分类学上与鲫鱼同属一种，与鲫鱼相比，金鱼在外部形态上产生了巨大的变异，但总体上整个鱼体可分为头部、躯干、尾部三个部分。头部的最前端是口，后部有鼻、眼和鳃盖。有些品种头部上端有肉瘤，有些品种鼻部上方有绒球，有些品种眼部凸出、位置朝上或有水泡，还有的品种鳃盖外漏形成翻鳃。金鱼躯干体披鳞片，主要有正常鳞、透明鳞和珍珠鳞。其侧面具有侧线，不同品种金鱼的侧线上鳞、侧线下鳞和侧线鳞数目不尽相同。典型的金鱼躯干具有胸鳍、腹鳍、臀鳍、背鳍和尾鳍，个别品种无背鳍或臀鳍。金鱼尾部由尾柄和尾鳍构成，其尾鳍形状变化多端。

金鱼一直在水面吐泡泡怎么办

　　1、缺氧

　　2、原因：缺氧会导致金鱼浮头或者是在水中吐泡泡，并且还会把嘴巴探出水面，就像在呼吸空气中的氧气。

　　3、治疗办法：可以先换水，新水的溶氧量高，换几次水就可以提高水中的溶氧量了。但是每次换水的量不要太多，换三分之一即可。也可以安装氧气泵，适量的增氧。

　　4、消化不良

　　5、原因：金鱼消化不良也会吐泡泡，就像人打嗝一样，一般都是因为喂食过多或者是吃了不易消化的食物。

　　【英文介绍/For English】：

　　Goldfish spitting bubbles on the water surface may be caused by low oxygen content in the water, high stocking density or excessive corruption in the water. The breeder can change the water or oxygenate in time according to the actual situation; it may also be because the goldfish has indigestion. Exhaust gas through self-regulation. In this case, you can stop feeding for 3 days and wait for the goldfish to digest by itself; it is also possible that the water temperature is too low or the water quality is too poor, which will also cause the goldfish to float on the water and spit bubbles. You can raise the water temperature to about 25 degrees as soon as possible, and change the water in time to maintain the water quality in the fish tank.

　　Morphological characteristics of goldfish:

　　Goldfish belongs to the same taxonomy as crucian carp. Compared with crucian carp, goldfish has huge variation in external shape, but in general the whole fish body can be divided into three parts: head, trunk and tail. The front of the head is the mouth, and the back has the nose, eyes and gill covers. Some species have sarcomas on the top of the head, some species have a pom-pom above the nose, some species have bulging eyes or blisters, and some species leak out of the operculum to form turning gills. The body of goldfish is covered with scales, mainly including normal scales, transparent scales and pearl scales. There are lateral lines on its sides, and the numbers of lateral line scales, lateral line underline scales and lateral line scales vary among different goldfish species. A typical goldfish body has pectoral, pelvic, anal, dorsal, and caudal fins, and individual species have no dorsal or anal fins. The tail of goldfish is composed of caudal peduncle and caudal fin, and the shape of its caudal fin varies widely.
