Pseudomugil sp. “Red Neon”—often referred to as the Red Neon Blue-Eye Rainbowfish—is a dazzling freshwater species native to Papua New Guinea. This species is admired for its brilliant red fins, iridescent blue body, and playful swimming behaviour. When kept in a group of six or more, their shimmering colors intensify, creating a mesmerizing display of natural beauty.

💧 Ideal for Beginners

Perfect for aquarists who are new to nano or community aquariums, this fish adapts easily to stable, clean water conditions. Its small size and peaceful temperament make it suitable for planted or aquascaped tanks.

🌿 Habitat & Tank Setup

Provide a densely planted tank with open swimming spaces. A dark substrate and floating plants help accentuate their natural coloration. Gentle filtration and stable parameters are essential for keeping them healthy and active. They thrive in groups, which reduces stress and encourages natural social interactions.

🍽️ Feeding

Red Neon Blue-Eyes are omnivorous and accept a variety of foods. A balanced diet of high-quality micro-pellets, crushed flakes, and occasional live or frozen foods such as daphnia or brine shrimp will ensure vibrant coloration and strong health.

🤝 Tankmates

They coexist harmoniously with small, non-aggressive species such as rasboras, small tetras, and dwarf shrimp. Avoid larger or fin-nipping fish.

🌈 Breeding

Breeding can occur in well-conditioned groups. Provide fine-leaved plants or spawning mops where females can deposit eggs. Fry can be raised separately with infusoria or powdered fry food.
