pH Range 6.5–7.5
Water Hardness 5–19 dGH

🧬 Behavior & Temperament

  • Temperament: Peaceful, calm, social

  • Swimming Style: Graceful but slow due to body shape and vision

  • Tank Level: Mid-to-bottom dwellers

  • Best Tankmates:

    • Other fancy goldfish (e.g., Oranda, Fantail, Ryukin)

    • Avoid fast single-tailed types (like Comets or Shubunkins)


🍽️ Diet

  • Type: Omnivore

  • Diet Options:

    • Sinking pellets/flakes made for goldfish

    • Blanched veggies: peas (deshelled), spinach, zucchini

    • Protein treats: bloodworms, daphnia, brine shrimp (live or frozen)

Feeding Tip: Feed 2–3 times daily in small amounts; avoid floating pellets to prevent gulping air and swim bladder issues.


❤️ Health & Lifespan

Common Issues Prevention/Treatment
Swim Bladder Disease Soak pellets; include fibrous veggies
Ich (white spots) Quarantine new fish; raise temp & salt
Fin Rot Maintain clean water; use antibacterial meds
Cloudy Eyes/Injuries Keep tank clean; remove sharp objects
  • Lifespan: 10–15 years; longer with excellent care


🥚 Breeding

  • Spawning Type: Egg scatterer

  • Sex Differences:

    • Males may develop white breeding tubercles on gill plates

    • Females become rounder when gravid

  • Spawning Setup:

    • Separate tank with fine-leaf plants or spawning mops

    • Spawning triggered by warmer water and longer light exposure

  • Post-Spawning: Adults should be removed to avoid egg-eating

  • Fry Feeding: Start with infusoria or liquid fry food, then baby brine shrimp


✅ Pros and Cons

Pros Cons
Beautiful velvety black color Color may fade with age or poor conditions
Peaceful and easygoing Prone to vision problems and injuries
Good for beginners with proper tank size Not suitable with fast or aggressive fish
Long lifespan Needs stable, clean water and soft décor

🧠 Tips for Success

  • Avoid strong currents—Black Moors are slow and get pushed around easily.

  • Choose gentle tankmates that won’t outcompete them at feeding time.

  • Monitor water quality regularly—fancy goldfish are sensitive to ammonia and nitrites.

  • Give them enough space—they’re large-bodied and need room to swim.
