Description

The glass tetra is a small, silvery characin of the family Characidae (true tetras) reaching about 10 cm. The slender body has an adipose fin (as in many characins), a black spot on the tail base and a striking red-gold upper half of the eye, which gives the species its charm. It comes from the fresh water of northern South America and lives in schools in clear streams and rivers with vegetated banks. As an omnivore it eats insects, zooplankton, algae and plant matter, taken in the water column and at the surface. In the rainy season it spawns among the water plants. For its size and handsome eyes it is a popular and hardy community aquarium fish.
