Description

The Ifati penguin tetra is a small tetra from the Maroni and Approuague basins of French Guiana in South America. The species grows to about 4 cm and has a slender, silvery body with a dark longitudinal stripe continuing into the lower tail lobe, characteristic of the penguin tetras, which therefore often hold an oblique, head-up posture. It forms schools in calm, shallow creeks with sandy and rocky bottoms. The fish is harmless to humans, popular in the aquarium trade and assessed as Least Concern (LC) by the IUCN.
