The marble axe fish is native to Peru. It inhabits slow rivers and lakes with dense vegetation.
Its pectoral fins are elongated and have highly developed muscles, which allow it to jump out of the water and glide. It resorts to jumping to escape from predators and to attack possible prey such as insects.
There is no clear sexual dimorphism and the female can only be identified when she is going to spawn by presenting an exaggerated belly bulge.
She deposits her eggs between the thin-leaved plants where they adhere and hatch after 30 hours.
