Blue King Tetra – Detailed Product Description

• Overview & Appearance
  The Blue King Tetra is a visually stunning freshwater fish admired for its rich, royal blue coloration and subtle metallic sheen. Its body often displays a gradient of deep blue tones with hints of silver or violet, depending on lighting and angle. Under aquarium lighting, the iridescence becomes more pronounced, giving it a glowing, almost regal presence—hence the name “King.” Its streamlined body and delicate fins allow it to glide gracefully through the water, especially when kept in a school. In a well-maintained tank, their colors intensify, making them a standout feature in any aquascape.

• Tank Size & Setup
  Blue King Tetras are schooling fish and should be kept in groups of at least 6–10 individuals. A minimum tank size of 15–20 gallons is recommended, though larger tanks (20–30 gallons or more) are ideal for maintaining a healthy and active school.
  For the best setup:

  • Use a planted aquarium with live plants like Java fern, Anubias, or Vallisneria

  • Include driftwood and natural decor for hiding spots

  • Opt for a dark substrate to enhance their blue coloration

  • Provide moderate lighting to bring out their iridescence without causing stress

A balanced aquascape helps them feel secure and display natural schooling behavior.

• Water Conditions
  Stable and clean water conditions are essential for the health of Blue King Tetras:

  • Temperature: 23°C – 27°C (73°F – 80°F)

  • pH Level: 6.0 – 7.5 (slightly acidic to neutral)

  • Water Hardness: 2 – 12 dGH (soft to moderately hard)

  • Filtration: Gentle to moderate flow; avoid strong currents

  • Water Changes: Weekly 20–30% water changes are recommended

Consistency is key, as sudden changes in water parameters can stress the fish and dull their coloration.

• Behavior & Temperament
  Blue King Tetras are peaceful, social, and active swimmers. They thrive in schools and exhibit beautiful synchronized swimming patterns when kept in proper numbers. Generally non-aggressive, they are ideal for community aquariums. They occupy the mid-water level and are constantly in motion, adding life and energy to the tank. When kept in small groups, they may become shy or less active.

• Tank Mates
  Thanks to their gentle nature, Blue King Tetras pair well with a variety of peaceful species:

  • Other small tetras (neon, cardinal, ember)

  • Rasboras

  • Corydoras catfish

  • Otocinclus

  • Dwarf gouramis

  • Peaceful livebearers like guppies and platies

Avoid aggressive fish, fin-nippers, or significantly larger species that may intimidate or prey on them.

• Feeding Habits
  Blue King Tetras are omnivores and easy to feed:

  • Staple Diet: High-quality flakes or micro pellets

  • Protein-Rich Foods: Brine shrimp, bloodworms, daphnia (live or frozen)

  • Supplemental Foods: Occasional plant-based foods like spirulina flakes

Feed small portions 1–2 times daily. A varied diet helps enhance their coloration and overall vitality.

• Care & Maintenance
  These tetras are relatively hardy and suitable for both beginners and experienced aquarists. To ensure their well-being:

  • Maintain stable water parameters

  • Avoid overfeeding

  • Perform regular tank maintenance

  • Provide adequate space and plant cover

They can be susceptible to common freshwater diseases like ich if stressed, so good water quality is essential.

• Breeding Information
  Blue King Tetras are egg scatterers and can be bred in captivity with the right conditions. A separate breeding tank with soft, slightly acidic water and dim lighting is recommended. Provide fine-leaved plants or spawning mops for egg laying. After spawning, remove the adults to prevent them from eating the eggs. Eggs typically hatch within 24–36 hours, and fry should be fed infusoria before transitioning to baby brine shrimp.

Its deep blue shimmer, easy care requirements, and compatibility with community tanks make it a versatile addition to any aquarium. Whether you are a beginner or a seasoned hobbyist, this elegant schooling fish will elevate the beauty and harmony of your aquatic setup.
