🐟 Blue Rainbowfish (Melanotaenia lacustris)
A Dazzling Electric Turquoise-Blue Body • A Rare Gem From a Highland Lake • A Glowing Shoal for the Planted Tank
 
📋 The Blue Rainbowfish, also known as the Lake Kutubu Rainbowfish or Turquoise Rainbowfish, carries a dazzling electric turquoise-blue body that glows under the light, with a dark stripe along each side and a silvery belly. Males shine the most intense blue of all, making a shoal one of the most eye-catching sights in any aquarium.
It comes from Lake Kutubu in the highlands of Papua New Guinea, where it lives in clear, mineral-rich water. Every Blue Rainbowfish we ship is feeding well.
This is a fast, peaceful shoaling fish that sweeps through the middle and upper levels of the tank, and it looks its best in a group of six or more. Males put on shimmering displays to each other and to the females, deepening their blue as they mature. It thrives in a planted tank and grows up to 12cm, so a 200L tank suits it well.
