Poecilia Reticulata 'Black Blue'

Poecilia Reticulata ‘Black Blue’ is a peaceful freshwater guppy suited to community aquariums, planted tanks, and aquarists interested in livebearer breeding. Its active behavior brings constant movement to the aquarium, while keeping several together supports natural activity and may help reduce stress.

As a community fish, this guppy can be kept with other small, non-aggressive species. Males typically show longer fins and stronger coloration, while females contribute graceful movement and resilience to the group. A 10-gallon aquarium can accommodate a small group of 4–6 fish, with additional space needed if the population grows.

Black Blue Guppy Care Requirements

• Temperature: 72–82°F (22–28°C)
• pH: 6.8–7.8
• Water hardness: Moderate, around 5–15 dGH
• Maintenance: Perform regular 20–25% weekly water changes
• Lighting and décor: Moderate lighting, gentle plants, and aquarium décor provide shelter while keeping the fish visible

Feed a quality flake or micro-pellet food, supplemented with live or frozen brine shrimp and daphnia several times per week. These feeding options support an active, varied diet and help maintain healthy fins and coloration.

Livebearer Breeding

Poecilia reticulata can reproduce reliably in a home aquarium. Plant-rich refuges or a separate fry-safe area give young fish protection, while free-swimming fry can be offered infusoria or finely crushed baby brine shrimp. This makes the Black Blue guppy a practical choice for community aquariums and for aquarists seeking an approachable introduction to breeding livebearers.
