Head & Tail Light Tetra

Head & Tail Light Tetra – Detailed Product Description

• Overview & Appearance
  The Head & Tail Light Tetra (Hemigrammus ocellifer) is a classic and elegant freshwater fish known for its distinctive glowing spots—one near the head and another at the base of the tail. These spots reflect light beautifully, resembling tiny “headlights” and “taillights,” which give the fish its popular name. Its body is translucent silver with subtle golden or iridescent tones, while the fins are mostly clear with slight hints of color. When kept in groups, the reflective spots create a shimmering effect as they move, adding a gentle sparkle to the aquarium.

• Tank Size & Setup
  Head & Tail Light Tetras are schooling fish and should be kept in groups of at least 6–10 individuals. A minimum tank size of 10–15 gallons is sufficient, though a 20-gallon tank or larger is ideal for a more natural display.
  Recommended setup:

  • Planted aquarium with live plants such as Java fern, Amazon sword, or Cryptocoryne

  • Open swimming space in the middle

  • Driftwood or natural décor for shelter

  • Moderate lighting to highlight their reflective spots

A balanced tank with both cover and open space will help them feel secure and active.

• Water Conditions
  They are relatively hardy but prefer stable conditions:

  • Temperature: 22°C – 28°C (72°F – 82°F)

  • pH Level: 6.0 – 7.5

  • Water Hardness: 2 – 15 dGH

  • Filtration: Gentle to moderate flow

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

Maintaining consistent water quality helps preserve their health and coloration.

• Behavior & Temperament
  Head & Tail Light Tetras are peaceful, social, and active swimmers. They are ideal for community tanks and rarely show aggression. They tend to occupy the mid-water level and display natural schooling behavior when kept in proper numbers. If kept in small groups, they may become shy and less active.

• Tank Mates
  Their calm temperament makes them highly compatible with other peaceful species:

  • Other small tetras (neon, glowlight, ember)

  • Rasboras

  • Corydoras catfish

  • Otocinclus

  • Dwarf gouramis

  • Small shrimp

Avoid aggressive or large fish that may intimidate them.

• Feeding Habits
  Head & Tail Light Tetras are omnivores and easy to feed:

  • Staple Diet: High-quality flakes or micro pellets

  • Protein Foods: Brine shrimp, daphnia, bloodworms

  • Supplemental Foods: Occasional plant-based foods like spirulina

Feed 1–2 times daily in small portions. A varied diet supports their overall health and enhances their subtle coloration.

• Care & Maintenance
  These fish are beginner-friendly and relatively low-maintenance:

  • Maintain stable water parameters

  • Provide a planted environment

  • Avoid overfeeding

  • Perform regular water changes

They are generally hardy but can be affected by common aquarium diseases if water quality declines.

• Breeding Information
  Head & Tail Light Tetras are egg scatterers and can be bred in captivity. A separate breeding tank with soft, slightly acidic water and dim lighting is recommended. Provide fine-leaved plants or spawning mops. After spawning, remove the adults to prevent egg predation. Eggs usually hatch within 24–36 hours, and fry should be fed infusoria before transitioning to baby brine shrimp.
