Complete Care Guide for Pearlscale and Pompon Goldfish — Health and Management Tips

Pearl Scale Goldfish

The Pearl Scale goldfish is a variety that originated in China, characterized by its body covered entirely in rounded, pearl-like raised scales (pearl scales). Its spherical body shape and distinctive textured, bumpy scale appearance create a unique presence.

Color variations are diverse, including red, white, red and white, blue, and black. The "Crown Pearl Scale," which develops a hood on the head, is also popular.

Pompon Goldfish

Pompon goldfish is a variety where the skin around the nostrils develops into soft, fluffy pom-poms that hang down. Its adorable appearance, like wearing fluffy decorations on its nose, is the reason for its popularity.

Pompons are extremely delicate, and injury can lead to bacterial infection risk. It's important to avoid sharp layout materials like rocks or driftwood, and create an environment where pompons won't get caught.

Swim Bladder Disease Risk and Prevention

This applies to round-bodied goldfish in general, but Pearl Scale and Pompon goldfish have swim bladder structures that differ from elongated goldfish, making them high-risk varieties for swim bladder disease (swim bladder dysfunction).

Main causes of swim bladder disease: - Low water temperature (15°C or below) causing reduced digestive function - Excessive consumption of air-filled dried food - Congenital swim bladder deformity - Bacterial or parasitic infection

Prevention tips: - Maintain water temperature constantly at 20-25°C (heater is essential) - Use sinking food to reduce air intake - Feed small portions multiple times daily - During water changes, avoid sudden temperature drops by slowly adjusting water temperature

Proper Water Quality Management

Round-bodied goldfish are poor swimmers, so strong water currents should be avoided. Sponge filters or low-flow top filters are ideal. Water quality targets:

• pH: 6.5-8.0
• Ammonia: 0 ppm (zero required)
