Blue Eye Gertrudae Rainbowfish (School of 6)
Start these small colorful rainbows out right by introducing them into the aquarium in a school. The Gertrudae will be more likely to swim in the open waters and not hide from potential predators (hopefully there aren’t any).

The rainbowfish are vibrant and active. I introduced six of them together and they swim freely in the tank. Easy to care for and don’t seem to fight with other fish. Great for a small community tank.
Jennifer Davies –
They arrived healthy and stayed active for several months. The colors are bright and they enjoy the floating foods I offer. A nice addition to my 10-gallon tank.

I love how they move through the water. They don’t hide and stay in the open areas. Very peaceful and don’t bother other fish. Perfect for beginners.
