General Description
The Wimpel Piranha, scientifically known as Catoprion Men, is a unique species that bears a striking resemblance to true piranhas and is closely related to Pygocentrus species. It is named for its protruding jaw structure and specifically adapted teeth used in its feeding behavior, where it swiftly bites and dislodges scales from its prey. This monotypic fish showcases stunning dorsal fin extensions in mature specimens.
Aquarium Setup
For optimal care, the Wimpel Piranha requires a tank with ample hiding spots such as dense plant cover, roots, and branches along with a dark substrate. A layer of floating plants is recommended to create dim conditions. Maintaining stable water conditions similar to its natural blackwater habitats through the addition of aquarium-safe peat is advisable. Avoid strong water flow to mimic its preferred environment.
Behaviour
This species is not suitable for community tanks as it tends to prey on small tankmates and can be aggressive towards larger fish, stripping them of fins and scales swiftly. While juveniles may form shoals, adult Wimpel Piranhas should ideally be housed alone due to increased belligerence, particularly in females that may incessantly attack males as they mature.
Feeding and Diet
In nature, the Wimpel Piranha primarily feeds on scales of both conspecifics and other species and has teeth specialized for this purpose. In captivity, it readily accepts chopped prawn, mussel, lancefish, and other meaty foods, eliminating the need for live fish in its diet.
Reproduction & Dimorphism
Information regarding the reproduction of the Wimpel Piranha remains unreported. Sexual dimorphism is observed in the convex anal fin of males, contrasting with the female's non-convex anal fin.
Habitat and Distribution
Found in rivers, streams, and tributaries across Colombia, Venezuela, Guyana, Brazil, and Bolivia, the Wimpel Piranha also inhabits the Pantanal wetlands in the Mato Grosso region, known for its abundance of aquatic plant life.
