Black blisters in the flag (definite introduction)

Black-blistered blister eyes are originally named because they have a bunch of large blisters under the eyeballs and are covered in black. The blisters in the eyes are originally filled with lymph fluid. In recent years, Zhaqiwu blisters are prized for their characteristics, which are as thick as ink black. Because it has a normal dorsal fin, it is named "Trailer". So how to identify the blister?

1. The size of the bubbles is uniform and symmetrical. There is no intention to choose bubbles that are too large here, because goldfish soaked in bubbles have poor oxygen resistance and will be difficult to increase ventilation due to excessive burden and endanger their lives. There are also different bubbles that have an extra horizontal rib in the middle of the bubble. From a distance, one bubble looks like it is divided into two, which has its own characteristics. If you encounter it, you may choose to buy it.

2. There are still requirements for the caudal peduncle. As egg species, many fish have the problem of a slender caudal peduncle. When choosing, you should choose a caudal peduncle that is thicker and shorter. Such fish have better physique and are better. look.

3. The tail leaf should be plump, that is, the tail leaf has a wider end. The length of the tail leaf is based on the complete cooperation, just take a good look.

4. Nowadays, you can occasionally see blister goldfish with jaw blisters, which are called "bubble goldfish". From what I understand, it should be caused by the loose cortex of the fish's jaw. As the fish breathes, , sucking in the water in the mouth to make the cortex blister-like. It turns out that if you carefully observe other types of goldfish, you can also find such a phenomenon, but it is rare to see symmetrical blisters on the body, so you can hide it if you find it.

5. Pay attention to the anal fin, as abnormal general offspring quality will be greatly affected.

6. Check the swimming posture and swimming power of the fish. Fish that swim normally and brilliantly are easier to raise.
