Hyphessobrycon bentosi

Hyphessobrycon bentosi, the ornate tetra, is a species of characin found in sluggish tributaries at the Amazon Basin in Brazil and Peru. It can grow up to 4 cm (1.6"). Males have longer dorsal and anal fins and appear slightly larger than females.[1] Occasionally, it makes its way into the aquarium trade. It has often been confused with the rosy tetra.

Distribution[edit]

The ornate tetra lives in sluggish tributaries of the Amazon River in the Amazon Basin.[2]

Diet[edit]

In the wild, this fish feeds on small invertebrates and is omnivorous.

In the Aquarium[edit]

Ornate tetras have been kept in the aquarium. They have been sold as bentos tetras, white tip tetras, or false rosy tetras in certain stores.[2]
