The red-eye tetra is perhaps the easiest species to keep. It lives in the Peruvian Amazon lowland, but all red-eyes in stores today are bred in farms in Florida or Singapore. With a maximum size of just 2 inches and large scales, they are small enough to fit any community aquarium, tough enough to act as dither fish for smaller cichlids, and big enough not to get eaten by angelfish and other species with a large mouth. In nature, red-eyes live in the upper portion of the water column but always in shallow water. Often, they are seen hovering in small troops of five to 10 fish under overhanging marginal plants or floating plants. This species very much likes to feed from the surface, hunting for insects and small crustaceans.
