RED FANTAILS

The Red Tail Comet Goldfish is a vibrant variant of the Comet goldfish, known for its bright red tail and streamlined body. It was first developed in the United States in the late 1800s and remains a favorite for both aquariums and outdoor ponds due to its beauty and resilience.

Physical Characteristics

• Body Shape: Slender and torpedo-like, built for speed and agility.
• Tail: Long, deeply forked, and flowing—often as long as the body itself.
• Coloration: Typically features a fiery red tail with a contrasting white or orange body, though some may be fully red.
• Size: Commonly grows to 6–7 inches, but can reach up to 12 inches in optimal conditions.
• Lifespan: 10–20 years with proper care.

Habitat & Tank Requirements

• Tank Size: Minimum of 40 gallons for one fish; add 50 gallons per additional fish.
• Water Temperature: 65–75°F (18–24°C).
• pH Range: 6.0–8.0.
• Substrate: Smooth gravel or sand to protect delicate fins.
• Plants: Hardy species like Java fern or Anubias are ideal—just be prepared for some nibbling!
• Filtration: Strong filtration is essential due to their high waste output.

Diet & Nutrition

• Omnivorous: Enjoys a mix of high-quality pellets, blanched vegetables (like peas and spinach), and protein-rich treats like brine shrimp or bloodworms.
• Feeding Tips: Feed small portions 2–3 times daily. Avoid overfeeding to maintain water quality.

Behavior & Temperament

• Social: Peaceful and active, they thrive in groups and enjoy open swimming space.
• Compatibility: Best kept with other single-tailed goldfish or similarly sized, non-aggressive fish.

Breeding

• Spawning: Egg-layers that breed in cooler water with seasonal cues.
• Challenge: Breeding is easier in ponds than in tanks due to space and environmental triggers.

Red Tail Comets are energetic, fast swimmers with peaceful temperaments, so their ideal tank mates should match their activity level, size tolerance, and cool-water preferences. Here’s a list of top companions that can thrive alongside them:

Best Tank Mates for Red Tail Comets

Tank Mates to Avoid

• Fancy Goldfish (like Orandas or Bubble Eyes): Too slow and delicate for Comets’ speed.
• Tropical Fish (like Guppies or Tetras): Prefer warmer water and may become snacks.
• Aggressive Species (like Cichlids): Too territorial and likely to stress or injure Comets.
