1. Historical Origins

The celestial eye goldfish likely originated in China or Korea during the 18th century. The earliest known record is a Chinese scroll from 1772, depicting a goldfish without a dorsal fin and eyes turned skyward. Contrary to myth, the upward gaze did not develop from narrow jars; it is purely genetic.

2. Distinctive Physical Traits

• Eyes: Telescope-like, turned vertically, giving a perpetual upward gaze.
• Body Shape: Elongated and egg-shaped, similar to bubble-eye goldfish.
• Fins: Lack a dorsal fin, which adds to their delicate nature.
• Color Patterns: Often a mix of white, orange, and gold, making them visually striking.

3. Development of Upward-Gazing Eyes

The celestial eye goldfish is not born with upward-gazing eyes. Within six months, the eyes reposition naturally, centering the pupils on the top of the head. This unique feature distinguishes them from other telescope goldfish.

4. Ideal Care and Maintenance

Caring for celestial eye goldfish requires attention to safety and water quality:

• Aquarium surfaces must be smooth to prevent eye injuries.
• Regular monitoring of temperature, pH, and ammonia levels is essential.
• Best kept in species-only tanks or with peaceful, slow-moving fish.
• Avoid overcrowding to minimize stress and physical damage.

5. Cultural Significance

The celestial eye goldfish has long been celebrated in Chinese art and literature. In 1960, it appeared on a Chinese postage stamp, symbolizing its cultural importance and popularity as a rare ornamental fish.
