The Dward Rainbowfish lives up to its name, because it only gets to be about 2 inches long. These fish tend to live for about 3 to 5 years. During this time they are known for being social and for being a schooling fish.
Definitely make sure your Dwarf Rainbowfish has at least 6 buddies to swim with. This is an easy breed to introduce to your tank of non-aggressive fish. This species will eat either meat or plants.
