RED/BLACK FANTAILS

Red and Black Fantail goldfish are a striking and somewhat uncommon color variation of the classic Fantail, known for their vivid contrast and graceful movement. Here’s what makes them stand out:

Appearance

• Coloration: These Fantails typically feature a blend of deep red or orange with bold black markings. The patterns vary widely—some have black-tipped fins, others sport marbled patches across the body.
• Body & Fins: Like all Fantails, they have a rounded, egg-shaped body and a flowing, double-lobed tail that fans out elegantly.

Size & Environment

• Adult Size: 6–8 inches
• Tank Size: Minimum 30 gallons for one; add 10–20 gallons per additional fish
• Pond Friendly: Yes, especially in temperate climates with proper depth and filtration

Water Conditions

• Temperature: 65–75°F (18–24°C)
• pH: 6.5–7.5
• Filtration: Gentle flow preferred to accommodate their slower swimming style

Diet

They thrive on a varied omnivorous diet:

• Sinking pellets or gel food
• Blanched veggies (like peas or spinach)
• Occasional treats like bloodworms or daphnia

Behavior & Compatibility

• Temperament: Peaceful and social
• Tank Mates: Best with other fancy goldfish; avoid fast or nippy species
• Activity: Curious and interactive, but not overly active

These beauties are not only eye-catching but also hardy and beginner-friendly.

Tank Mates

Red/Black Fantails are peaceful, slow-moving fancy goldfish, so their ideal tank mates should share similar temperaments and environmental needs. Here are some of the best companions for them:

Compatible Tank Mates

• Other Fancy Goldfish (like Calico Fantails, Orandas, Ryukins, or Black Moors): They match in swimming speed and care requirements.
• White Cloud Mountain Minnows: Hardy, peaceful, and tolerant of cooler water.
• Dojo Loaches (Weather Loaches): Bottom dwellers that enjoy similar temperatures and won’t compete for food.
• Bristlenose Plecos: Algae eaters that generally leave goldfish alone—just ensure they’re not too large or aggressive.
• Apple Snails or Nerite Snails: Great for algae control and won’t bother your Fantails.

Tank Mates to Avoid

• Fast or Nippy Fish (like Barbs or Danios): They may outcompete Fantails for food or nip at their fins.
• Tropical Fish: Most require warmer water and may not thrive in goldfish-friendly temperatures.
• Common or Comet Goldfish: These are much faster swimmers and can stress out slower fancy varieties.

Health Considerations

• Common Issues: Swim bladder disorder, fin rot, ich
• Prevention: Maintain clean water, avoid sudden temperature changes, and quarantine new fish

Breeding

• Spawning: Triggered by temperature changes and seasonal cues
• Egg Care: Remove adults post-spawning to prevent egg predation

Fantails are a joy to keep—graceful, interactive, and full of personality. With the right setup and a little attention, they can live 10–15 years or more.

If you're planning a community tank, aim for a spacious setup with gentle filtration and plenty of open swimming space.
