Scientific name: Moenkhausia sanctaefilomenae
The Red-Eye Tetra is one of the larger tetras, growing to 2.5 inches. It is an undemanding species as long as the water quality is good and there is room for a group to swim actively in the tank. The Red-Eye Tetra is a fin-nipper, though; keep it with short-finned companions that are the same size or a bit larger.

The Red-Eye Tetra does well at a water temperature in the range of 68º to 78º Fahrenheit, a pH between 5.5 and 8.5, and soft to relatively hard water. Flake and freeze-dried foods are fine, although an occasional feeding of live brine shrimp is recommended.
