The Melanotaenia Picta - Aru Rainbowfish is a spectacular centerpiece for the modern freshwater aquarium, known for its brilliant coloration and sophisticated social behavior. Characterized by a shimmering silver-to-gold body accented with neon orange highlights and a distinct black mid-lateral line, this species is a masterclass in aquatic aesthetics. In the "Answering Machine" era of specialized rainbowfish husbandry, the Aru Rainbowfish is highly prized for its rarity, athletic profile, and its ability to add high-velocity color to larger planted systems.
Unlike more common rainbowfish, the Aru variety possesses a unique, localized color pattern that intensifies significantly as the fish matures and settles into a stable environment. 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.
Note: Images shown are stock images and not the actual fish you will receive.
Care Level: Easy to Moderate
Temperament: Peaceful
Variant Size: Standard
Minimum Tank Size: 30 Gallons
Diet: Omnivore
Reef Compatible: N/A (Freshwater)
Max Size: 4 Inches
Temperature: $75^\circ$ to $82^\circ$F
dKH: 5 to 15
pH: 7.0 to 8.0
The Aru Rainbowfish is an ideal candidate for a larger community planted tank. While they are highly adaptable, they require a long tank with plenty of open swimming space to accommodate their active nature and high-oxygen requirements. 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, natural 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.
