Crown Pearlscale

Crown Pearlscale key facts

Care level

Intermediate

Lifespan

5-6 years

Temperature

15〜28℃

Diet

Prepared foods, frozen bloodworms

Lighting

Diffuse lighting best shows the grain of the pearl scales and the shape of the head growth. Strong light from directly above tends to flatten the relief of the scales.

Housing

Use a simple layout without sharp edges so the thickened pearl scales are not scraped, and keep the flow gentle. The type is sensitive to cold, so do not let winter temperatures fall too far.

Tank Mates

It does not swim well, so pair it with equally slow fish such as the ping-pong pearl or the bubble eye. Wakin types and comets will outcompete it for food.

Notes

Head growth suffers when water quality declines and rarely recovers. It is a different fish from the hamanishiki, whose head growth is more developed and blister-like, and the two are sometimes confused in shops.

About Crown Pearlscale

The Crown Pearlscale is a Chinese goldfish known for its pearl-like round scales and a pair of symmetrical head growths. With a plump body and calm temperament, it's suited to intermediate keepers and typically lives 5 to 6 years.

7 things to know before welcoming a Crown Pearlscale

1. 1Round Body, Pearl Scales

   The Crown Pearlscale has a plump, rounded body covered in pearl scales, each one raised into a dome shape. These scales catch the light like strings of pearls, and their size and arrangement vary from fish to fish, adding to each individual's character.

2. 2The Head Growth Develops Over Time

   The bumps on top of the head, known as the wen, are barely noticeable in young fish and gradually become more pronounced with age. The most prized fish have two evenly sized, clearly separated bumps, so patience is part of raising one to its full form.

3. 3A Slow, Gentle Swimmer

   Because of its rounded body shape, the Crown Pearlscale swims more slowly and gently than slimmer goldfish varieties. Pairing it with similarly calm, slow-moving tankmates helps avoid stress from competition over food.

4. 4Mind Its Digestion

   Round-bodied goldfish varieties are thought to be more prone to digestive strain, so portion size and feeding pace matter. Offering smaller amounts and watching how the fish responds is a safer approach than feeding heavily all at once.

5. 5Keep Water Conditions Stable

   This variety is sensitive to sudden swings in water quality and temperature, so regular water changes and a stable environment are important. This day-to-day attentiveness is part of why the Crown Pearlscale is considered better suited to intermediate keepers.

6. 6Protect the Delicate Scales

   The raised scales are delicate, so it's best to avoid sharp-edged decor and coarse substrate in the tank. Handle the fish gently when netting it, since scales can be knocked loose through rough contact or collisions with tankmates.

7. 7Prepare the Tank in Advance

   To properly showcase the head growth and scale pattern, it helps to set up a reasonably spacious tank with plenty of water volume before bringing one home. Having a suitable filter and substrate ready in advance reduces unnecessary stress on the fish.
