The Blue Neon Guppy (Poecilia reticulata) is one of the most visually captivating and hardy tropical fish available for freshwater aquariums. With its shimmering neon-blue hues and active, peaceful temperament, this guppy is perfect for both novice and experienced aquarists. Native to South America, guppies have been selectively bred for generations to produce stunning color varieties like the Blue Neon.

🌿 Ideal Aquarium Setup

A well-balanced aquarium setup ensures your Blue Neon Guppies thrive. A 10-gallon tank is sufficient for a small group, though larger tanks allow for more natural schooling behavior.
Use fine gravel or sand substrate, live plants (like Java moss, Anubias, or Water Wisteria), and gentle filtration to maintain water clarity. Stable temperatures between 22°C–28°C (72°F–82°F) help maintain their health and coloration.

Maintain clean, stable water parameters with weekly 25–30% water changes. Avoid strong currents, as guppies prefer calm waters.

🍽️ Diet & Feeding

Blue Neon Guppies are omnivorous, thriving on a mix of:

• High-quality flake or micro-pellet food

• Frozen or live foods (brine shrimp, daphnia, bloodworms)

• Occasional vegetable supplements (spirulina flakes or blanched spinach)

Feed small portions 2–3 times daily to prevent overfeeding.

🤝 Compatibility

Peaceful and social, Blue Neon Guppies coexist well with:

• Other guppy varieties

• Corydoras catfish

• Neon tetras

• Mollies, platies, and small rasboras

Avoid housing them with aggressive or fin-nipping species (e.g., tiger barbs or bettas).

🌸 Breeding Information

One of the easiest species to breed in captivity, guppies are livebearers, meaning females give birth to free-swimming fry. Provide floating plants or breeding grass to protect the fry from adult fish. Separate the fry for best survival rates.

💡 Care Tips for Beginners

• Maintain consistent water temperature with a reliable heater.

• Test water weekly using an aquarium test kit.

• Provide both hiding spaces and open swimming areas.

• Keep a small group (1 male : 2–3 females) to reduce stress.
