Poecilia Reticulata 'Red Koi'

Poecilia Reticulata ‘Red Koi’ brings vivid red coloration and active livebearer behavior to the freshwater aquarium. Its pale body creates a strong contrast with the brilliant red fins, making this guppy especially noticeable in planted aquariums, open layouts, and low-to-moderate lighting.

This beginner-friendly guppy is peaceful with other small, non-aggressive fish and is well suited to community tanks. Males typically display more pronounced fin length and intense red coloring, while females add graceful movement and resilience to the group. Keeping several together supports natural activity and helps reduce stress.

Care Requirements

• Tank size: A 10-gallon aquarium is suitable for a small group of 4–6 fish; provide additional space if the group will grow.
• Temperature: Maintain 72–82°F (22–28°C).
• pH: Keep the water around 6.8–7.8.
• Hardness: Moderate hardness of 5–15 dGH is recommended.
• Maintenance: Regular 20–25% weekly water changes help support healthy fins and strong coloration.

Feed high-quality flake or micro-pellets, supplementing with live or frozen brine shrimp and daphnia a few times per week. Moderate lighting, gentle plants, and aquarium décor provide shelter and breeding areas while allowing the red tones to stand out.

As a livebearer, this guppy can reproduce reliably in a home aquarium. Use plant-rich refuges or a separate fry-safe area when raising young, and offer tiny foods such as infusoria or finely crushed baby brine shrimp to free-swimming fry. It is a practical choice for aquarists seeking colorful community fish or an approachable introduction to livebearer breeding.
