The Oranda Goldfish was originally bred in China as most goldfish breeds were (although some breeds were further developed in Japan).

The Chinese named the breed “the flower of the water” because of their graceful swimming habits and their physical appearance.
While we may know these fish as simply the Oranda, the Japanese refer to them as Oranda Shishigashiri.
Like all goldfish, Orandas are a descendant of the wild Carp. However, this is one of the only goldfish breeds to resemble the Carp barely at all.

Physical Characteristics: How To Identify The Oranda In An Aquarium
This goldfish breed is a fat little fish with a brain-like growth on the top of their heads.
This brain-like growth begins to develop when the fish are around the age of 4 months old.
The growth should be fully developed when the Oranda is around the age of 2 years old. Although, some Orandas take a little longer to develop it.
