2.(Goldfish,Egg-fish)Black Duplex Bubble-eye

Bubble-eye is well known for having special bubbles, which include red, red and white, and multicolored ones, while black ones are not so common. This variety is as deep dark as black velour, and what is most appreciated is two bubble-eyes of similar size growing in tandem on each side. This is a special variation among Bubble-eyes and is extremely rare and precious.
