Colombian Tetra

Colombian Tetra (Hyphessobrycon colombianus) Information

The Colombian Tetra is a vibrant and peaceful species of freshwater fish, popular for its striking appearance and calm nature. Native to South America, these tetras are known for their eye-catching colors and are often kept in community tanks due to their friendly temperament. Colombian Tetras are relatively easy to care for, making them a great choice for both beginner and experienced aquarists.

Scientific Name:

Hyphessobrycon colombianus (Colombian Tetra)

Maximum Size:

• The Colombian Tetra typically grows to a maximum size of 2.5-3 inches (6-8 cm).

• Their size makes them well-suited for smaller to medium-sized aquariums.

Native Region:

• The Colombian Tetra is native to the rivers of Colombia and other regions in South America.

• They are typically found in slow-moving streams, rivers, and heavily vegetated areas with clear water and neutral pH levels.

Diet (Carnivorous or Omnivorous?)

• Omnivorous, meaning the Colombian Tetra will consume both plant-based and animal-based foods.

• In the wild, they feed on a variety of small invertebrates, insects, and plant matter.

• In captivity, they thrive on:
  ✅ High-quality flake food or small pellets.
  ✅ Live or frozen foods such as daphnia, bloodworms, and brine shrimp.
  ✅ Vegetable matter, including blanched spinach, zucchini, and peas.
  ✅ Algae-based foods to mimic their natural diet.
  ❌ Avoid overfeeding, as it can lead to water quality issues and obesity.

Lifespan:

• Colombian Tetras generally have a lifespan of 3-5 years in captivity, though some individuals may live longer if kept in optimal conditions.

Breeding Season & Behavior:

• Colombian Tetras are egg layers and are relatively easy to breed in captivity under the right conditions.

• Spawning typically occurs in soft, acidic water with plants or spawning mops where the female can lay her eggs.

• The male fertilizes the eggs externally, and after about 24-48 hours, the eggs will hatch into fry.

• The breeding season for Colombian Tetras is typically during the warmer months, and they may breed year-round in stable tank conditions.

• Water temperature and quality play a crucial role in successful breeding, with slightly acidic to neutral water (pH 6.0-7.0) and a temperature range of 74-80°F (23-27°C) being ideal.

Best Tank Mates:

Colombian Tetras are generally peaceful and social fish, making them great additions to community aquariums. However, they can become somewhat territorial during the breeding season or if kept in small tanks, so providing ample space and hiding places is recommended.

✅ Other peaceful species (Neon Tetras, Guppies, Corydoras, Platies, Mollies)
✅ Small to medium-sized peaceful cichlids (Apistogramma, Rams)
✅ Other tetras (Ember Tetras, Black Phantom Tetras, Rummynose Tetras)
✅ Snails (Nerite Snails, Mystery Snails)
✅ Shrimp (Amano Shrimp, Cherry Shrimp)

🚫 Avoid:

• Aggressive species (such as large cichlids or predatory fish) that could harm or stress the Colombian Tetra.

• Fin-nipping species, as Colombian Tetras have delicate fins.

Ideal Tank Conditions:

• Tank Size: A 20-gallon tank is the minimum for a small school of Colombian Tetras, though a larger tank (30 gallons or more) is ideal to allow for more swimming space.

• Temperature: 74-80°F (23-27°C), as they are tropical fish that prefer warmer water.

• pH: 6.0-7.0 (slightly acidic to neutral).

• Water Hardness: Soft to moderately hard water is best for Colombian Tetras.

• Filtration: Moderate filtration is important to keep the water clean and clear, but avoid strong currents as these fish prefer calmer waters.

• Décor:

  • Planted tanks work well for Colombian Tetras, as they enjoy swimming through plants and having hiding spaces.

  • Fine gravel or sand is the best substrate.

  • Driftwood and rocks can also be added to provide additional hiding spots.

  • Floating plants help create a natural environment and provide areas of shade.

⚠ Important Notes:

• Colombian Tetras are peaceful and do well in community tanks, but they should be kept in schools of at least 5-6 individuals to reduce stress and encourage natural schooling behavior.

• They are sensitive to water conditions, so regular water changes and maintaining stable parameters is crucial to their health.

• These fish do well in planted aquariums where they can graze on algae and have plenty of space to swim.

• The breeding season can be triggered by temperature changes and the addition of spawning mops or live plants.

• Regular tank maintenance and feeding are important to keep these fish in good condition and prevent disease.
