🐟 Dwarf Neon Rainbowfish (Melanotaenia praecox)
A Shimmering Neon-Blue Body With Bright Red Fins • A Compact Rainbowfish for Smaller Tanks • A Lively, Peaceful Shoal
📋 The Dwarf Neon Rainbowfish, also known as the Neon Rainbowfish or Praecox Rainbowfish, carries a shimmering metallic neon-blue body that flashes as it turns, set off by bright red fins on males and golden-yellow fins on females. It's one of the most dazzling small rainbowfish, packing big colour into a compact size.
It comes from the Mamberamo River basin of West Papua, Indonesia. Every Dwarf Neon Rainbowfish we ship is feeding well.
This is a lively, peaceful shoaling fish that darts through the middle and upper levels of the tank, and it looks its best in a group of six or more. Its small size makes it perfect for planted community tanks, where its neon shimmer really shines. It grows up to 6cm, so a 100L tank suits it well.
