Variety characteristics of butterfly tails
The butterfly tail in the goldfish is a species of goldfish of the dragon species, named after its wide, stretched tail and butterfly-like tail, of which rugao, Jiangsu and other places are the most famous.

The characteristics of the butterfly tail are the same as those of the dragon's eye goldfish, that is, the eyeball is particularly developed, protruding outside the eye socket, in addition, the tail fin of the butterfly tail goldfish is very developed, and the entire tail fin is stretched out, or like a "V" shape or like an "X", like a butterfly, very beautiful. The most beautiful butterfly tail goldfish is its large tail like a butterfly, and the degree of anti-warp of its leading edge directly determines the quality of its quality, generally the anterior edge of the tail fin and the body side angle between 90 degrees to 45 degrees, the fin end up to the gills and even near the eye is better, in addition to good shape, the strength of the tail of the tail fin spinous bone is also very demanding.

Detailed explanation of the selection of butterfly-tailed goldfish
1, the head should be wide, such a fish ornamental effect is good, and generally the fish will grow faster, the skeleton is relatively large.
2, butterfly tail as a dragon's eye goldfish, naturally to the abacus bead type and the size of the left and right sides of the same as the upper product, but now the butterfly tail eyeball is generally small, not protruding enough.
3. If the pedigree of the butterfly tail is relatively good, the end of the pectoral fin is generally rounder, which can be used as one of the bases for judging the purity of the butterfly tail variety.
4. The butterfly tail is divided into straight type, reverse warp type and fan round type, the straight type is generally straight here, and the reverse warp and fan circle are inverted arc.
5, the end of the tail leaf is wider, so narrow, it is possible that this is a fish with a better tail shape selected from the ordinary dragon's eye goldfish, that is, the original shape of the butterfly tail goldfish, the manifestation of impure variety.

。 8, the tail leaf edge of the butterfly tail is close to the straight line, such as the concave arc is obvious, the tail is very thin, the ornamental effect will decline, naturally it is also a manifestation of the impurity of the fish species, and this fish is not resistant to breeding.
9. If the head and body junction are in a gentle straight line, the size of the fish will be longer and the ornamental value will be lower. Here it is generally required to have a certain angle, most like a gilded goldfish for a high back shape.
10, tail handle and tail seat, generally require the tail stalk of the fish to be short and thick, the tail seat is best to be semi-circular, which is conducive to the display of tail shape, usually this type of fish grows faster.
