The red-eye tetra adds a touch of glamour to a freshwater community aquarium. Their metallic look, dynamic energy, and signature red-eye with its pop of color combine to create an elegant display when kept in a school of six or more. This fish is a good choice as a beginner fish. Water conditions fluctuate much in its natural habitat, so this fish can tolerate a wide range of differences and changes. The red-eye tetra is a relatively larger tetra and should ideally be housed in a 20-gallon or larger aquarium.
Origin and Distribution
They are found in South America in Paraguay, eastern Bolivia, eastern Peru, and western Brazil. In the wild, they inhabit clear rivers but can sometimes be found living in the thick vegetation of the murky Amazon. Aquarium specimens are now bred extensively in Asia.
Colors and Markings
If you have ever seen a school of these tetras with their bright silver body accented by a black tail and red eyes, it is obvious how they got their name. This peaceful medium-sized tetra is readily available and suitable for most community aquariums.
