The appreciation of tiger-headed goldfish is mainly divided into three aspects: swimming posture, color and body shape. Look at the color first. For solid goldfish, it is required that the color is pure and there is no noise. The top grade is the one whose color penetrates the abdomen and the tip of each fin. Two-color goldfish requires clear color contrast, clear boundaries and beautiful color block distribution. Especially for Zhu Ding and Yu Ding, it is required that the color does not overflow the tumor end. The first-class color separation blocks such as red are divided into black and white, and the stable colors such as purple and blue are the top grades. The best five flowers are blue flowers on a white background, with red tops and five-color patches. In terms of body shape, the tiger-headed goldfish requires that the head pile is solid and huge, seamless, the snout is prominent and developed, the body is vigorous, the scales are arranged neatly, and the proportion of the head is moderate. Because the tiger's head is round and short, there is no dorsal fin, and the caudal fin is very small, so the paddling efficiency of caudal fin and caudal handle is very high. A good tiger tail fin should be symmetrical, open and powerful, and the angle of upper and lower leaves is reasonable. The included angle between the caudal fin and the caudal stalk can be effectively combined with the back curve to make up for the bad influence of physical characteristics on the balance of goldfish. The swimming posture of the tiger-headed goldfish is also very important. Tiger-headed goldfish are required not to lean forward or look up when resting. When swimming, you can move freely back and forth, up and down, with quick response and quick movements.

1, "head"

A good tiger-headed goldfish should first have a densely developed head with sarcoma, and the fluff should be delicate and crystal clear, which is also the primary key for the tiger-headed goldfish to be liked by the majority of fish friends. Therefore, whether head sarcoma is developed is very important. Developed sarcoma is not only longer than the top of the head, but also longer than the upper mouth (snout), gills and mandible.

The "body" tiger head is a "short fin" goldfish. Whether the length and shape of each fin are correct or not has a great influence on its ornamental value. As far as the overall feeling is concerned, we should first stress uniformity: the tail handle is thick, the tail fin is symmetrical left and right, and the included angle is reasonable, which should be in proportion to the body shape. The caudal fin should be stretched naturally, that is, neither drooping nor upturning, so that the fish can maintain balance and stability whether swimming or standing. In addition, the proportion of body length should be moderate; The body is thick and well proportioned. Because it is thick, the balance of the body is strong and the balance of the tail is relatively greater. 3. "holiness" (1), a good tiger head should have a pair of prominent and full snouts (called "dragon balls" by some fish friends), as well as a well-developed "head cover" and a "gill cover" with sarcoma, which set off a brave head and a broad back. If a certain part is slightly inferior or excessive, it will make the whole posture and momentum out of balance and become a poor tiger.

(2) How to connect the head, back, waist, caudal tube and caudal fin into a beautiful line in side view is the main point of side view evaluation. The back line starts from the plump "headgear" and connects along the neck, back, waist, tail tube and tail fin like a semicircle, thus completing the beautiful back line.

4. "Color" color is also an important evaluation standard for tiger fish. But what color scheme is the best? It is difficult to have a standard answer. However, as long as the color of tiger-headed goldfish is bright and strong, the spots are clear and bright, and the arrangement of color blocks is harmonious and changeable, it will meet our standards for color requirements. Specifically, the pure red tiger head should be bright and pure, and the two-color and three-color tiger head blocks should be beautifully inlaid, symmetrical or in sharp contrast. The tiger's head with a large blue background should be inlaid with black, white, red or yellow, which looks like a beautiful ink painting. There are also some tiger heads with transitional colors. It depends on the appearance after the transition color, and it is necessary to have foresight to pick the tiger-headed goldfish you like. 5. "Swimming posture" Tigers attach great importance to swimming posture, which emphasizes elegance and nobility, no hurry and no delay, and a king's demeanor. Basically, you can tell whether the swimming posture is good or not by looking at the goldfish's figure. The shape and softness of caudal fin have the greatest influence on swimming posture. The pro-bone is too hard and rigid for swimming, so the pro-bone should be elastic, and the tail should be soft first and then moderate, so that the swing will be beautiful. If the tail fin is too flat (the tail does not go down first) and the water is cut flat, it is difficult to push the body. What's more, the tail fin is upturned, so that the body will be upturned every time you swim. In short, to have a good figure, besides being beautiful, its swimming posture is also very dynamic.
