Yellow Widow Tetra

Description

• Yellow Widow Tetra (Hyphessobrycon bifasciatus) is a small, vibrant freshwater fish known for its striking yellow coloration and peaceful nature. Here’s a detailed description:

  Physical Characteristics:

  • Size: Typically grows to about 1.5–2 inches (4–5 cm) in length.

  • Color: Bright yellow-gold body with subtle iridescence. Males may display deeper yellow or orange hues, especially during breeding.

  • Fins: Transparent to slightly yellowish fins, sometimes with white or black edges. The adipose fin (small fin between dorsal and tail) is a key feature.

  • Markings: Some specimens may have faint dark stripes running along the body, remnants of its “bifasciatus” (two-striped) namesake.

  Behavior & Temperament:

  • Peaceful and schooling – Does best in groups of 6 or more.

  • Active swimmer but not overly aggressive; suitable for community tanks.

  • May display mild territorial behavior among males during breeding.

  Habitat & Care:

  • Tank Size: Minimum 20 gallons for a small school.

  • Water Conditions:

    • Temperature: 72–82°F (22–28°C)

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

    • Soft to moderately hard water preferred.

  • Diet: Omnivorous – thrives on flakes, micro-pellets, live/frozen foods (brine shrimp, daphnia) and vegetable matter.

  Tankmates:

  • Compatible with other small, peaceful fish like neon tetras, rasboras, dwarf cichlids, and Corydoras.

  • Avoid large or aggressive species that may intimidate them.

  Breeding:

  • Egg-scatterer; requires soft, acidic water and dense plants for spawning.

  • Parents may eat eggs, so separation is recommended.

  Notes:

  • Sometimes confused with the “Yellow Phantom Tetra” (Hyphessobrycon roseus), but lacks the pink/red hues.

  • A hardy species but benefits from stable water conditions and a planted tank.
