Rummynose

1. Physical Characteristics

• Coloration: Rummynose Tetras are known for their vibrant coloration, featuring a silver body with a bright red patch on the nose and a distinctive black spot near the base of the tail. The colors may appear even more vivid in tank-raised specimens due to optimal lighting and nutrition.
• Size: They typically grow to about 2-2.5 inches (5-6.5 cm) in length.
• Lifespan: With proper care, Rummynose Tetras can live for 5-8 years in captivity.

2. Natural Habitat and Distribution

• Origin: Rummynose Tetras are native to the rivers of the Amazon Basin in Brazil. They are often found in slow-moving waters with dense vegetation.
• Tank Environment: In captivity, they thrive in well-planted aquariums that mimic their natural habitat, providing plenty of cover and swimming space.

3. Behavior and Temperament

• Peaceful Schooling Fish: Rummynose Tetras are social and should be kept in groups of at least 6-10 individuals. They are active swimmers and enjoy schooling behavior, often found swimming in the middle layers of the tank.
• Social Behavior: Generally peaceful, they can be housed with other non-aggressive species. They are known for their lively nature and will interact with each other and their tank mates.

4. Aquarium Care

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

  Water Parameters:

  • Temperature: 74-82°F (23-28°C).

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

  • Water Hardness: 4-12 dGH (soft to moderately hard water).

  • Filtration and Aeration: They prefer well-oxygenated water, so a good filtration system is essential. Gentle 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. Adding driftwood and rocks can create hiding spots and enhance the overall environment.

5. Diet

• Omnivorous: Rummynose 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 Rummynose Tetras can be achieved under the right conditions. They are egg scatterers and prefer spawning in soft, well-planted areas.
• Mating Behavior: Males may display more vibrant colors during breeding and can be seen courting females with swimming displays.
• 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: Rummynose Tetras are generally peaceful and can be housed with other similarly sized, non-aggressive species.

  Good tank mates include:

  • Other small tetras (such as Neon Tetras or Cardinal Tetras).
  • Rasboras, including Harlequin or Scissortail Rasboras.
  • Corydoras catfish, small loaches, or other peaceful community fish.

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

8. Fun Facts

• Striking Appearance: The bright red coloration of their noses is one of their most distinctive features, which makes them very popular among aquarists.
• Active Schoolers: They are known for their schooling behavior, making them a dynamic addition to community tanks.
• Sensitive to Water Quality: Rummynose Tetras are sensitive to changes in water conditions, so maintaining stable parameters is crucial for their health.

9. Importance in Aquariums

• Visual Appeal: Their striking colors and active behavior make them an attractive addition to community tanks.

• Beginner-Friendly: Rummynose Tetras are relatively easy to care for and can thrive in a variety of setups, making them suitable for both novice and experienced 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.
