Yanagi Demekin

The Yanagi Demekin is a striking goldfish that combines the slender, streamlined body of the Wakin with a long, flowing ribbon tail and the protruding eyes characteristic of the Demekin. Because judging standards for this variety at competitive shows have never been firmly settled, many individuals get culled during selective breeding, making it a genuinely uncommon find. Its swimming style stays close to the agile Wakin, and its calm temperament makes it easy to keep alongside other goldfish. That said, its bulging eyes are prone to injury from bumping into objects, so tank layouts should avoid sharp or cluttered decorations. Considered suitable for intermediate keepers, it offers an appealing contrast between its unusual appearance and lively swimming.

Yanagi Demekin key facts

Care level
Intermediate
Lifespan
10-15 years
Temperature
15〜28℃
Diet
Prepared foods, frozen bloodworms
Lighting
As a wakin type it suits viewing from the side or above and needs no special lighting; enough to show the sweep of the long tail is plenty.
Housing
It swims quickly like any wakin type, but the eyes project, so keep the layout simple and free of sharp edges. Fit a cover, as these fish jump.
Tank Mates
Fast wakin types and comets may peck at its eyes. Choose companions of similar build that are not inclined to nip.
Notes
A damaged eye does not recover. Keep equipment clear of the eyes when netting or changing water. Circulation is small and the fish is hard to find.

About Yanagi Demekin

Yanagi Demekin pairs a Wakin-style body with a flowing ribbon tail and protruding Demekin eyes. Rarely seen due to unsettled judging standards and heavy culling, it's an agile, calm goldfish suited to intermediate keepers.

7 things to know before welcoming a Yanagi Demekin

  1. 1Eye Care & Injury Risk

    The protruding eyes inherited from the Demekin lineage can easily bump into sharp corners or hard decorations, leading to injury or inflammation. Choose smooth, rounded tank decor and filter intakes that won't scrape against the eyes.

  2. 2Choosing Tank Mates

    Thanks to its agile, Wakin-like swimming, it rarely bullies slower fish, but pairing it with very fast, active fish can increase collisions that injure its eyes. Goldfish with a similar swimming speed make the best companions.

  3. 3Basic Water Quality

    Goldfish produce a lot of waste relative to their food intake, so regular water changes and a filter with solid capacity are essential. Stable water quality is especially important for Demekin-type eyes, which are prone to trouble.

  4. 4Suitable Tank Size

    Because it swims actively, a cramped tank won't give it enough room to move and can cause stress. Provide a spacious tank with plenty of open swimming area.

  5. 5Feeding Guidelines

    Its digestive system isn't especially robust, and overfeeding in a single sitting can lead to problems like swim bladder disorder. Offer small amounts across several feedings and remove leftover food promptly.

  6. 6Prepare Before You Find One

    Since judging standards for this variety remain unsettled, many individuals get culled during selection, so it rarely appears on the market. If you come across one you like, having your tank set up in advance lets you bring it home smoothly.

  7. 7Difficulty & Who It Suits

    Considered suitable for intermediate keepers, it calls for some attention to eye care from its Demekin side and an environment matched to its active, Wakin-like swimming. It's a good fit for keepers with some existing goldfish experience.
