Takara Tomy's goldfish series. Respectively from left to right: yellow ryukin and red pearlscale. P. S.: The ryukin fish came with the rider doll and different stand, it was considered one of the secret rare ones, I guess. Fun fact about goldfishes: The round body varieties with double tail are considered the "fancy" varieties. They are the result of 2000 years of selective breeding, they have about half the lifespan of their unilateral brothers (up to 10 years), require warmer temperatures (18C-24C) and less space (at least 50 litres per individual). Because of their unnatural form they are very prone to degenerative diseases, they are also slow and shouldn't be kept with predators or faster species, because they are not very good competing for food or avoiding trouble.
