Goldfish Varieties - Ranchu

The Ranchu is the Japanese variant of goldfish bred from the Lionhead. It is not difficult to characterize this particular goldfish, as it can be easily identifiable by its short, round body with thick fins. Perhaps if you observe carefully you will notice that one of the most prominent features is the lack of dorsal fin. The tail can be made up of 4 lobes and is very short in length. Ranchu rarely grows beyond 15cm measured from head to end of tail fin. Similar like its lionhead cousin, it has a hood on its head, which looks like a raspberry outgrowth protruding from the skin.

The goldfish is also known for its colorful feature and is usually found in red, orange or white striking combinations. Ranchu is a highly prized and sought after goldfish not only in Japan but also other parts of the world including America and Europe. In fact, the Japanese are so fond of it and competitions were organized during autumn each year to select the best fish. The art of judging and selecting the best Ranchu comes from the few basic concepts outlined below.

  • Eyes should be evenly placed, small and protrude clearly from the headgrowth
  • The stomach should form a smooth curve starting from the gill to the end of the abdomen
  • When seen from above, the back of Ranchu should be broad and properly aligned with the body and finally,
  • The scales must be complete and regular with no visible deformity in sight

No doubt with its elegant and unique characteristics, Ranchu has always remained to be one of the most popular goldfish. In Japan, this hobby is highly revered upon and refined to perfection. It is one of the most beautiful goldfish, which remains one of my favorite besides the pearlscale.

About Me

My Photo

My fascination and interest towards aquarium fish has led me to devote my time towards caring and learning about this wonderful pet.

Aquarium fish keeping is a very challenging and exciting hobby. When I first started, I never knew much or have the necessary guidance back then because none of my family members were actually a keen hobbyist. And because of that, I’ve encountered numerous failures and the worst part is having to deal with dead fish every time when you started to grow fond and getting attached to my pets. However, I persevered and took steps to find out and search for information from other hobbyist, apart from the knowledge gained and learned from my own experience and research. The blog that I’ve created here is meant to share useful information and tips about aquarium fish keeping so that new hobbyist will not make the same mistakes that I’ve made in the past."
