You will be dazzled when you see those colorful and graceful schools of golden fish. However, in order to choose a good goldfish, it is necessary to understand the relevant knowledge of goldfish. The selection criteria of goldfish can be roughly selected from the following seven aspects. Let's choose with the editor!

Goldfish

1. If the fish is thin or not, it means poor nutrition. Pick a fat belly swollen. If the fish is swimming, it only shakes its head and does not move its body, and it shows tiredness, it means that it has a thin fish disease and cannot be avoided.

2. Whether the goldfish live in a group Can only be selected from the group. Pick from the colony those fish that swim against the bottom of the pool while looking for bait. Those fish are healthy.

3. Whether the head and tail are well-proportioned, and some fish have uneven tails and long tails. Dragon eyes and blisters are named after the features of the eyes. So if its eyeballs are big or small, it's not up to par. If you look closely, you'll see that many fish don't have the same size eyeballs.

4. For color selection, choose black, not gray or black gray; crimson, not red, yellow or yellow. Some red fish are the color of small carrots. it is good. Some fish are half black and half red, or red with black edges on the fins. They seem to be very beautiful, but in fact, they will soon turn into full red, so be foreshadowed.

5. Whether there are broken fins and scales. Because goldfish grow into juveniles after hatching, they will be displayed and sold in the aquarium from the production pond (basin) to the store, and some fins will be transported in the middle. The strips and scales are easy to tear and fall off. When the dorsal and caudal fins of goldfish are fished out and brought in, the fin rays are easy to break, the fin leaves are easy to crack, and the scales on both sides of the abdomen are easy to rub off. For red and black fish, after the scales are removed, the fish will reveal the grayish white of the skin, which is easy to see.

6. The choice of caudal fins For species with four large tails, the middle of the dorsal caudal fin of the fish must be split to form two double drooping four open tails. , very beautiful, leisurely. Therefore, if it is found that the middle of the back of the caudal fin is not split, but it looks like a three-layer front head, it is a remnant.

7. Don't buy fish that often float their heads. When you see individual fish out of the group, they always like to head up and tail down and float to the surface to suck and spit. This phenomenon is called floating head. A little lack of oxygen in the water can't stand it, and it's hard to get through the dog days. In short, the selected fish should be healthy, disease-free, colorful, and have the characteristics of various species. Don't get which one is which, it will waste money and affect the viewing.
