The Tosakin goldfish is a very beautiful and distinctive variety of goldfish with a large tail fin that extends horizontally behind the fish.
It is also called curly goldfish and was developed in Japan. He is believed to be from the Ryukin family.
Currently, the fish is mainly available in Japan and is rarely found in other countries.
The Tosakin Goldfish was first bred by a low-ranking samurai in Kochi Prefecture (formerly known as Tosa Stronghold) in Shikoku, Japan.
And this diversity probably did not reach other parts of the country until the middle of the 20th century.
The Tosakin variety of goldfish nearly died out after the earthquake, but was revived in the mid-20th century. However, for more information on this type of fish, read below.
Characteristics of Tossakin goldfish
The Tosakin goldfish has a short, egg-shaped body. They are similar in shape to other varieties of goldfish.
The caudal fins of these fish are open, flat, and widely spaced horizontally, and the leading edges drop once or even twice.
They are weak and even clumsy swimmers due to their large, broad tails.
Tosakins have a complete dorsal fin, and all other fins are also intact (except for the main features of this tail).
The inner edges are webbed, while the outer lobes are inverted and curled towards the head (so that the tail appears to have been turned upside down).
It is the only species of goldfish with an indivisible double tail. And their tail forms a perfect semi-circle when viewed from above.
Tosaquin goldfish are usually orange or orange-white in color. But, as you know, they come in black, yellow, chintz, red, red and white.
The average body length of an adult Tosakin goldfish is 4 to 8 inches. Photos and information from Wikipedia.
