Lemon Tetra (Hyphessobrycon pulchripinnis): Species Profile

The Lemon Tetra is a small, vibrant freshwater fish native to the Amazon River basin in South America. Known for its striking yellow coloration and peaceful demeanor, it is a popular choice among aquarists seeking to add a splash of color to community tanks.

Species Overview

• Common Name: Lemon Tetra
• Scientific Name: Hyphessobrycon pulchripinnis
• Adult Size: Approximately 1.5 inches (4 cm)
• Lifespan: 4 to 8 years

Appearance

Lemon Tetras exhibit a translucent yellow body with a subtle silver sheen. Their dorsal and anal fins are accented with black and yellow markings, and their eyes feature a distinctive red upper half, which intensifies with good health and proper care.

Behavior and Temperament

These tetras are peaceful, schooling fish that thrive in groups of six or more. They are active swimmers, often occupying the middle regions of the aquarium. Their calm nature makes them excellent companions in community tanks with other non-aggressive species.

Tank Requirements

• Tank Size: A minimum of 20 gallons is recommended to accommodate a small school and provide ample swimming space.
• Water Parameters:
  • Temperature: 72–82°F (22–28°C)
  • pH: 5.5 to 8.0
  • Hardness: 3 to 15 dGH
• Substrate: Dark substrates enhance their coloration and mimic their natural habitat.
• Decor: Incorporate live plants, driftwood, and rocks to offer hiding spots and create a natural environment.

Diet

Lemon Tetras are omnivorous and accept a variety of foods:

• High-quality flake or pellet food
• Live or frozen foods such as brine shrimp, daphnia, and bloodworms
• Occasional vegetable matter like blanched spinach or zucchini

Feeding them a varied diet enhances their coloration and overall health.

Tank Mates

Due to their peaceful nature, Lemon Tetras coexist well with:

• Other small tetras
• Rasboras
• Corydoras catfish
• Dwarf gouramis
• Small livebearers like guppies and platies

Avoid housing them with larger, aggressive fish that may view them as prey.

Breeding

Breeding Lemon Tetras in captivity is achievable with proper conditions:

• Breeding Tank: Set up a separate tank with soft, slightly acidic water (pH around 6.0–6.5) and a temperature of approximately 75°F (24°C).
• Spawning: Introduce a conditioned pair; the female will scatter eggs among fine-leaved plants or spawning mops.
• Post-Spawning: Remove adults to prevent egg predation. Eggs typically hatch within 24–36 hours, and fry become free-swimming shortly after.
• Feeding Fry: Start with infusoria or commercially prepared fry food, transitioning to finely crushed flake food as they grow.

Health and Disease

Maintaining optimal water quality is crucial to prevent common freshwater diseases. Regular water changes, a balanced diet, and avoiding overcrowding help ensure their well-being. Always quarantine new fish before introducing them to the main tank to prevent disease transmission.

By providing appropriate care and a suitable environment, Lemon Tetras can be a vibrant and engaging addition to any freshwater aquarium.
