How to choose high-quality butterfly-tailed goldfish I. Body shape
1. If you don't keep short butterflies, you must plant them in the future.
2, the head should be wide, so that the fish has a good ornamental effect, and generally the fish will grow faster and have a larger skeleton;
3. If the butterfly tail has a good pedigree, the end of pectoral fin is generally round, which can be used as the inspection point for the purity of butterfly tail varieties;
4. Butterfly tails can be divided into straight type, inverted type and fan type, in which the straight type is generally a straight line, and the inverted type and fan type are inverted arcs;
6. Butterflies that are too upturned are basically planted for 2 years.
7. Generally, the ratio of tail length to body length is greater than or equal to 1: 1, and the ratio of tail length to body length is called Fluttershy tail;
8. If the connection between the head and the body is a flat straight line, the fish will be longer and have lower ornamental value. It is generally required to have a certain angle here, most like a gold-plated goldfish with a high back shape;
Second, the eyes
1, butterfly tail, as a goldfish in a dzi bead, naturally takes abacus bead shape as the top grade, but now the eyeball of butterfly tail is generally small and not prominent enough;
2. The proportion of butterfly eyes is surprisingly high.
3. Butterflies with too big eyes are basically big eyes and small eyes. Butterflies with too big eyes will not gain weight.
Third, the tail
1 Hua Die's tail is very hard.
2. The tail leaf end of butterfly-tailed goldfish is wider, so it is narrower here. It is possible that this is a fish with a good tail, which is the prototype of butterfly-tailed goldfish, selected from ordinary dzi-bead goldfish, and the variety is not pure. The butterfly with a fan-shaped tail has a sharp tail, so that the left and right tail leaves can form a fan-shaped tail.
3, three-tailed butterfly, the most beautiful posture, and will not be awkward.
4. The tail of butterfly-tailed goldfish should not be too forked. Generally, it's best to cut into a straight line, but the tail blades can't rub against each other and the splitting angle can't exceed 15 degrees.
5. The edge of the tail leaf of the butterfly tail is close to a straight line. If the concave arc is obvious, the tail will be very thin and the ornamental effect will decrease, which is naturally a manifestation of impure fish species;
6. Tail handle and tailstock. Generally, it is required that the tail handle of fish is short and thick, and the tailstock should be unfolded in a semicircle, which is beneficial to the display of the tail shape of butterfly.
Fourth, color.
1, the color of black and white butterflies can be preserved very little. Under normal circumstances, the faded one of the blue butterflies does not exceed 1 year and a half, and all become completely white.
2, a fishing ground can really reach the upper middle 12 red, and it will be lucky to have one in two years.
There are fewer and fewer butterflies. The main reason is that white stripes should be eliminated when seedlings are grown. This ratio is quite large, so it is better to raise fish of other colors. After all, fish of other colors are less eliminated. Moreover, there are too few five Hua Die genes, and the probability of big eyes and small eyes is far greater than that of butterflies of other colors.
If many people don't know about goldfish, they often think that the Japanese Tosa goldfish is our father in China. Actually, it's not. Japanese Tosa goldfish belongs to literary goldfish, while China's butterfly tail is characterized by large and small eyes, so we must pay attention to the difference when choosing.
