Head & Tail Light Tetra Fish

Key Characteristics & Appearance

• Luminous Accents: Features two glowing, copper-gold to intense orange spots—one directly above the eye (“head light”) and another at the base of the caudal peduncle (“tail light”).
• Translucent Body: Possesses a semi-translucent, silver-gray body with a subtle iridescent sheen under proper aquarium lighting.
• Distinct Markings: Exhibits a small black spot overlaying the tail light and another faint humeral spot behind the gill cover, adding contrast to its delicate frame.
• Compact Size: Typically grows to an adult length of 1.5 to 2 inches (4 to 5 cm).

Behavior & Temperament

• Peaceful & Social: Completely non-aggressive and well-suited for peaceful community aquariums with non-predatory tankmates.
• Schooling Preference: Best kept in groups of 6 or more (ideally 8 to 10). In larger numbers, they form tight shoals, showcase brighter reflective colors, and display natural group dynamics.
• Active Swimmers: Occupies mid-to-lower water levels, bringing lively movement to the aquarium without harassing other inhabitants.

Care & Aquarium Setup

• Minimum Tank Size: 15 to 20 gallons to provide adequate horizontal swimming space for a school.
• Substrate & Aquascaping:
  • Dark Substrate: Dark gravel or sand enhances the contrast of their reflective spots.
  • Planting & Cover: Prefers a well-planted aquarium with dense background vegetation, floating plants for muted lighting, and open swimming space in the center.

Diet & Nutrition

• Omnivorous Diet: Accepts high-quality micro-pellets, fine flakes, and small sinking granules.
• Nutritional Variety: Thrives when fed live or frozen treats such as daphnia, baby brine shrimp, and cyclops, which help maintain their health and color intensity.
