📌 Detailed Product Description

• Species Overview & Visual Appeal

  • The Pearlscale Goldfish is one of the most distinctive fancy goldfish varieties, instantly recognizable by its perfectly rounded, golf-ball-like body and raised, bead-like scales.

  • Each scale has a calcified, domed appearance, giving the fish a “pearl-studded” texture that reflects light beautifully—this is what makes it a true collector’s piece.

  • Available in a range of colors including red, white, orange, calico, and even metallic combinations, with some variants like “Crown Pearlscale” featuring additional headgrowth (wen).

  • Unlike sleek fish, this species is all about form and texture over speed, making it a centerpiece in slow, elegant aquariums.

---

• Behavior & Temperament

  • Extremely peaceful, slow-moving, and gentle—one of the calmest fancy goldfish types.

  • Best kept with other similarly slow fancy goldfish.

  • Due to its rounded body, it is a weak swimmer and can struggle in strong currents or competitive environments.

  • Displays curious and interactive behavior—often approaches the glass during feeding.

  • Important Insight:

    • Their body shape makes them more vulnerable—tank design and tank mates must be carefully chosen.

• Ideal Tank Conditions

  • Tank Size: Minimum 75–100 liters for one fish; 120L+ recommended for stability and growth.

  • Temperature: 18°C – 24°C (cool water).

  • pH Range: 6.5 – 7.5.

  • Water Hardness: Moderate (6–18 dGH).

  • Filtration: Strong biological filtration required due to goldfish waste.

  • Flow: Gentle—low current is essential.

  • Aquascape Setup:

    • Smooth substrate (fine sand or bare bottom).

    • Avoid sharp decorations—scales are delicate.

    • Provide open space for easy movement.

  • Pro Tip:

    • A shallow tank layout can benefit pearlscales, as it reduces effort needed to swim to the surface.

• Tank Mates (Compatibility Strategy)

  • Best kept with other fancy goldfish of similar swimming ability.

  • Ideal Tank Mates:

    • Oranda

    • Ranchu

    • Lionhead

    • Bubble Eye (with caution)

  • Avoid:

    • Fast goldfish (e.g., Comet, Shubunkin)

    • Fin-nippers (e.g., barbs)

    • Tropical fish requiring higher temperatures

  • Strategic Insight:

    • Mixing with faster fish leads to food competition, resulting in malnutrition and stress.

• Feeding Habits & Nutrition

  • Omnivorous but prone to digestive and buoyancy issues due to body shape.

  • Diet should include:

    • High-quality sinking pellets (primary)

    • Gel foods (excellent for digestion)

    • Vegetables:

      • Shelled peas (key for preventing swim bladder issues)

      • Spinach or lettuce

    • Occasional protein treats:

      • Bloodworms

      • Brine shrimp

  • Feeding Frequency: 1–2 times daily, small portions.

  • Optimization Tip:

    • Avoid floating foods—they increase risk of air intake and buoyancy problems.

---

• Growth Rate & Size Potential

  • Typically grows to 15–20 cm (6–8 inches) depending on care and environment.

  • Growth is slower compared to streamlined goldfish due to body structure.

  • Important:

    • Overfeeding to “bulk up” can lead to health issues—growth must be balanced with health.

---

• Care & Maintenance

  • Water Changes: 30–50% weekly.

  • Monitoring:

    • Floating or sinking issues → diet imbalance or swim bladder problem

    • Missing or damaged scales → injury or infection

  • Disease Risks:

    • Swim bladder disorder (common)

    • Scale damage due to fragile structure

    • Bacterial infections if water quality is poor

  • Handling Note:

    • Extremely delicate—avoid rough handling; scales can be permanently damaged
