The Melanotaenia Praecox - Neon Dwarf Rainbowfish (3cm) is a spectacular centerpiece for the modern freshwater aquarium, known for its brilliant coloration and sophisticated social behavior. Characterized by a shimmering iridescent blue body and vibrant red fins, this 3cm variant is a masterclass in aquatic aesthetics. In the "Answering Machine" era of specialized rainbowfish husbandry, the Neon Dwarf Rainbow is highly prized for its compact size, athletic profile, and its ability to add high-velocity color to smaller planted systems.
Unlike larger rainbowfish species, the Neon Dwarf variant remains small enough for mid-sized setups while maintaining the same intense neon-blue reflectivity. They are exceptionally active swimmers that occupy the middle and upper levels of the water column, providing a constant display of color and alert, schooling movement.

Care Level: Easy
Temperament: Peaceful
Variant Size: 3cm
Minimum Tank Size: 20 Gallons
Diet: Omnivore
Reef Compatible: N/A (Freshwater)
Max Size: 2.5 Inches
Temperature: 72° to 82°F
dKH: 5 to 15
pH: 6.8 to 7.5
The 3cm Neon Dwarf Rainbowfish is an ideal candidate for a community planted tank. While they are highly adaptable, they require a tank with plenty of open swimming space to accommodate their active nature and benefit from high-oxygen water. They are high-metabolism fish and should be fed a varied diet of high-quality flakes, micro-pellets, and frozen meaty foods—such as mysis and vitamin-enriched brine shrimp—at least twice daily. Because they are schooling fish, keeping them in groups of six or more is mandatory to ensure they feel secure and display their most vibrant, iridescent colors.
We’ve dialed in the logistics for national Overnight Delivery to ensure your livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs, designed to maintain stable temperatures throughout the journey. We handle the technical side of the move so you can focus on the acclimation. Our protocol is built on getting these fish from the facility to your tank with zero compromise on health or vitality.
