Horyu

Horyu key facts

Care level

Advanced

Lifespan

5-6 years

Temperature

15〜28℃

Diet

Prepared foods, frozen bloodworms

Lighting

Provide enough light for the raised pearl scales to read from above and from the side. The blue body colour shifts with the angle of light, so diffuse lighting suits it.

Housing

Use a simple layout without sharp edges and keep the flow gentle so the pearl scales and protruding eyes are not damaged. It is sensitive to cold, so watch that winter temperatures do not fall too far.

Tank Mates

It does not swim strongly; pair it with other pearlscale types or slow breeds such as the bubble eye and celestial eye. Wakin types will take the food first.

Notes

Thickened pearl scales regrow poorly and damaged eyes do not recover. The variety is difficult to produce, circulation is limited, and the line is maintained by the enthusiasts' association.

About Horyu

Horyu is a Japanese goldfish combining a blue-tinted body, pearl scales, telescope eyes, and a head wen. Bred over thirty years by an amateur enthusiast and unveiled in 1994, it's an advanced-level variety.

7 things to know before welcoming a Horyu

1. 1An advanced variety, hard to produce

   Horyu requires all four of its defining traits to stay in balance, and it's considered an advanced-level fish to keep. Even keepers with goldfish experience should watch its condition more closely than usual, and it's not the best first choice for someone brand new to the hobby.

2. 2Watch out for bumps to the eyes

   Horyu's prominent telescope eyes can easily be bumped or scraped on tank decor and hard edges. Keeping the layout simple and avoiding sharp-edged obstacles helps protect this delicate feature.

3. 3Caring for the head wen

   The wen covering Horyu's head is one of its signature features, but it's also a spot where debris can collect. Water quality has a direct effect on its condition, so regular water changes and careful monitoring matter.

4. 4A calm nature, but consider tankmates

   Because of its telescope eyes and wen, Horyu has limited vision and swims less nimbly than slender goldfish varieties. Pairing it with fast, agile fish raises the risk of missed meals and collisions, so it's best kept with other calm, similarly bodied goldfish.

5. 5A lifespan of around five to six years

   Horyu typically lives around five to six years. Since that's a real long-term commitment, it's worth confirming beforehand that you can keep up with the daily care and tank maintenance it needs.

6. 6Avoid sudden shifts in water conditions

   Horyu is considered a somewhat delicate variety, and sudden changes in water temperature or chemistry can easily cause stress or health problems. Take extra care with acclimation when introducing it to a new tank, and avoid abrupt changes during everyday maintenance.

7. 7Prepare the setup before bringing one home

   Before bringing a Horyu home, it's worth setting up a tank layout without sharp edges that could injure its eyes or wen, along with filtration that can maintain stable water quality. Consulting with an experienced keeper while you prepare can help things go smoothly.
