Neon Tetra (Paracheirodon innesi) is a small, colorful, and peaceful freshwater fish native to the streams and rivers of South America, particularly in the Amazon basin. It is highly favored by aquarium enthusiasts for its striking appearance and ease of care.
Physical Characteristics:
Neon Tetras are easily recognizable by their vibrant, iridescent coloration.
- Size:
They typically grow to about 1.5 inches (4 cm) in length. - Colors:
Neon Tetras have a bright blue stripe running from their head to the tail and a red stripe that starts mid-body and extends to the tail. Their belly is silvery white, creating a striking contrast. - Lifespan:
They live 5–8 years with proper care in a well-maintained environment.
Behavior and Temperament:
Neon Tetras are peaceful, social fish that thrive in groups.
- Schooling Behavior:
They feel most comfortable in schools of six or more and display synchronized swimming patterns. - Temperament:
Non-aggressive and compatible with other peaceful community fish, making them ideal for mixed aquariums.
Habitat and Care:
Neon Tetras require specific conditions to mimic their natural habitat and thrive in captivity.
- Tank Size:
A minimum of 10 gallons is recommended for a small school. - Water Conditions:
- Temperature: 21°C–27°C (70°F–81°F)
- pH: Slightly acidic to neutral (6.0–7.0)
- Hardness: Soft water is preferred.
- Lighting:
Neon Tetras prefer subdued lighting to replicate the dim conditions of their natural environment. Adding live plants and driftwood can create shaded areas. - Diet:
Neon Tetras are omnivores. They thrive on a varied diet of high-quality flakes, micro-pellets, and occasional live or frozen foods like brine shrimp and daphnia.
Tank Mates:
Due to their peaceful nature, Neon Tetras can coexist with other small, non-aggressive species. Suitable tank mates include:
- Guppies
- Corydoras Catfish
- Harlequin Rasboras
- Small Gouramis
Avoid keeping them with large or aggressive fish like cichlids, which may view them as prey.
Breeding:
Breeding Neon Tetras in captivity is challenging but possible with careful preparation.
- Spawning Conditions:
A separate breeding tank with soft, slightly acidic water and dim lighting is necessary. - Eggs and Fry:
After laying eggs, adults should be removed to prevent them from eating the eggs. The fry hatch in about 24 hours and require fine powdered food or infusoria.
Popularity:
Neon Tetras are one of the most commonly kept aquarium fish worldwide due to their beauty, hardiness, and suitability for beginner and experienced aquarists. They add vibrant color and dynamic movement to community tanks.
