This blog is a journal of our experiences in raising, keeping, and breeding ranchu goldfish.
The ranchu is a type of fancy goldfish with a round body and short fins, with no dorsal fin. The head of a ranchu is covered with headgrowth, called the "wen".
Ranchu were originally developed in Japan, where they were kept in ponds and were designed to be viewed from above. They are referred to as "top view ranchu", or TVR. Later, breeders in China and Thailand began to develop "side view" ranchu, or SVR, which are designed to be kept in glass aquariums and viewed from the side.
SVR are more popular here in the US, where most people keep their fish in glass tanks, although there are some breeders who specialize in the traditional Japanese TVR.
Here at Ranchu Gardens, we have decided to focus on SVR goldfish, since we keep them indoors in glass tanks, and we prefer the more rounded body shape of the SVR. Also, SVR are available in a wide variety of colors, unlike Japanese ranchu, where only red or red/white are considered acceptable. My favorites are the Thai Black Ranchu, which will be the main focus of this blog.
