Bloodfin

1. Physical Characteristics

• Coloration: The Bloodfin Tetra has a silver body with a distinctive bright red or orange coloration on its fins, particularly the dorsal, anal, and tail fins. The body may also have a subtle sheen under certain lighting conditions.
• Size: They typically grow to about 2-2.5 inches (5-6.5 cm) in length.
• Lifespan: With proper care, Bloodfin Tetras can live for 3-5 years in captivity.

2. Natural Habitat and Distribution

• Origin: Native to the freshwater rivers and streams of South America, particularly in regions of Brazil, Paraguay, and Argentina. They are often found in slow-moving waters with abundant vegetation.
• Tank Environment: In captivity, they thrive in well-planted aquariums that provide hiding spots and open swimming areas.

3. Behavior and Temperament

• Peaceful Schooling Fish: Bloodfin Tetras are peaceful and do best in groups of at least 6-10 individuals. They are active swimmers, often occupying the mid-to-upper levels of the tank.
• Social Behavior: These fish are social and display more vibrant colors and better behavior when kept in schools. They can exhibit playful behavior and may chase each other, but they are generally non-aggressive.

4. Aquarium Care

• Tank Size: A minimum tank size of 15-20 gallons is recommended for a small school of Bloodfin Tetras. A larger tank (20 gallons or more) is preferable to provide ample swimming space and stability in water conditions.

  Water Parameters:

  • Temperature: 70-82°F (21-28°C).

  • pH: 6.0-7.5 (slightly acidic to neutral water).

  • Water Hardness: 5-12 dGH (soft to moderately hard water).

  • Filtration and Aeration: They prefer well-oxygenated water, so a good filtration system is essential. Moderate water flow is ideal.

• Aquascaping: Provide open swimming areas along with dense planting using soft-leaved plants like Java fern, Amazon sword, and floating plants. Incorporating driftwood and rocks can create hiding spots and enhance the overall environment.

5. Diet

• Omnivorous: Bloodfin Tetras are omnivores and require a varied diet.

  Diet Options:

  • High-quality flake or pellet food formulated for tropical fish.
  • Live or frozen foods such as brine shrimp, bloodworms, and daphnia.
  • Plant-based foods, including spirulina and algae wafers, to ensure balanced nutrition.

  Diet Variation: A diverse diet helps maintain their health and enhances their coloration.

6. Breeding

• Egg-Laying Species: Breeding Bloodfin Tetras in captivity is possible but may require specific conditions. They are egg scatterers and will lay their eggs on fine-leaved plants or spawning mops.
• Mating Behavior: Males may display vibrant colors during breeding and can be seen chasing females before spawning.
• Hatching: Eggs usually hatch in about 24-36 hours. Once the fry are free-swimming, they should be fed infusoria or specialized fry foods until they are large enough to eat baby brine shrimp or finely crushed flakes.

7. Tank Mates

• Compatible Tank Mates: Bloodfin Tetras are peaceful and can be housed with other similarly sized, non-aggressive species.

  Good tank mates include:

  • Other small tetras (such as Neon Tetras or Rummy Nose Tetras).
  • Rasboras, including Harlequin or Scissortail Rasboras.
  • Corydoras catfish or small loaches.

  Avoid Aggressive Fish: Larger or aggressive species should be avoided, as they may stress the Bloodfin Tetras or compete for food.

8. Fun Facts

• Colorful Display: Their bright red fins become even more vivid when they are excited or in a breeding mood, making them visually striking in the aquarium.
• Active Swimmers: Bloodfin Tetras are known for their playful and active swimming patterns, making them a lively addition to community tanks.
• Small Schooling Fish: They thrive in groups, exhibiting natural schooling behavior that enhances their display and the overall aquarium experience.

9. Importance in Aquariums

• Visual Appeal: Their bright coloration and active behavior make them a popular choice for community tanks.

• Beginner-Friendly: Bloodfin Tetras are relatively easy to care for and can thrive in a variety of setups, making them great for new aquarists.

  Key Care Tips:

  • Stable Water Conditions: Regular water changes and good filtration are crucial for their health and overall appearance.
  • Group Size: Keep them in schools of 6-10 or more to encourage natural behaviors and enhance their vibrant coloration.
  • Balanced Diet: A varied diet with both plant and protein-based foods will help them maintain their health and overall appearance.
