Dwarf Neon Rainbowfish

The Dwarf Neon Rainbowfish (Melanotaenia praecox) is a small, vibrant schooling fish with a shimmering blue body and bright red or yellow fins. Its iridescence really pops under good lighting, making it a favorite for planted aquariums.

Key Care Points:

• Behavior & Swimming: Peaceful and very active. Best kept in schools of 6 or more, where they display their best colors and lively schooling behavior. They are mid-to-top-level swimmers, constantly moving and exploring open space.

• Tank Requirements: Open swimming areas and some plants or driftwood for cover and gentle to moderate flow.

• Diet: Omnivorous. Eats flakes, pellets, and loves small live or frozen foods like brine shrimp, bloodworms, and daphnia.

• Lifespan: Typically 3–5 years with good care.

• Max Size: Grows up to 2–3 inches (5–7.5 cm).

• Growth Rate: Moderate; juveniles grow quickly and reach near-adult size in about 6–8 months.

The Dwarf Neon Rainbowfish’s constant motion and electric color make them a great choice for adding life and brightness to community tanks.
