关于白金

Platinum medaka is a selectively bred variety in which iridophores (guanine crystals) are expressed abundantly across the entire body, producing a uniform silver metallic sheen that shifts subtly depending on the angle of light. Developed through the wave of medaka breeding advances from the 2000s onward, it became one of the earlier improved varieties to achieve broad, stable popularity. The body shape is a standard fusiform, with typical fin proportions, meaning the fish is easy to keep as well as visually striking. Platinum medaka are gentle by nature and tend to school together, so keeping a small group brings out their most natural, lively behavior. Their hardiness and adaptability to a range of water conditions make them a popular first choice for new medaka keepers, and their bright silver gleam looks equally at home in a lotus pot, a planted aquarium, or an outdoor biotope pond.

迎接白金前需要了解的6件事

1. 1Tank Size Guide

   Although small in size, aim for 1–2 liters of water per fish to maintain stable water quality. A 20–30 liter tank is suitable for a group of around 10 fish. A more spacious setup also allows you to appreciate the metallic sheen at its best.

2. 2Lighting for Best Shimmer

   The metallic luster that defines Platinum medaka is best showcased under proper lighting. White LED lights or natural indirect light bring out the shimmer on their bodies. Avoid prolonged direct sunlight, as it can raise water temperature quickly.

3. 3Water Temperature and Quality

   The ideal water temperature is around 15–28°C, making Platinum medaka fairly adaptable to Japan's seasonal changes. Avoid summer heat above 30°C and sudden winter drops; outdoors, consider insulation and shade. Maintaining a slightly acidic to neutral pH (6.5–7.5) helps keep them in good condition.

4. 4Feeding Type and Frequency

   Commercial medaka-specific pellets or flakes provide sufficient nutrition. Feed once or twice a day in amounts they can finish within 3–5 minutes. Remove any uneaten food with a dropper to prevent water quality from deteriorating.

5. 5Breeding Traits and Tips

   Breeding begins when water temperature exceeds 18°C; females attach eggs to spawning mops or aquatic plants. Since adult fish may eat eggs and fry, transferring eggs to a separate container after spawning improves survival rates. Pairing Platinum with Platinum helps maintain the metallic trait in offspring.

6. 6Initial and Ongoing Costs

   Prices per fish range from a few hundred to several thousand yen depending on quality and lineage. Initial setup costs for a tank, filter, and lighting typically fall between 5,000 and 20,000 yen. Monthly upkeep—food and water—usually amounts to just a few hundred yen, making them an affordable pet to maintain.
