Nannocharax Brevis

Datasheet

General Description

The African Darter Characin, scientifically known as Nannocharax Brevis, is a captivating species within the Nannocharax genus, characterized by its inquisitive nature and distinctive swimming style of "hovering" and "chopping" around the tank. Typically growing up to 4.5cm in size, these fish are notoriously tricky to identify due to their resemblance to other species, such as Hemigrammocharax. They make for engaging aquarium inhabitants, compensating for their lack of vibrant colors with their vibrant personalities.

Aquarium Setup

For optimal care, it is recommended to house the African Darter Characin in heavily planted aquariums with ample shaded areas provided by aquatic vegetation. Smooth pebbles, driftwood, and rocks can be included to enhance the habitat and offer hiding spots for the fish. Mimicking their natural habitat of fast-flowing rivers and streams, a tank setup with coarse gravel substrate, water-worn rocks, and driftwood branches is preferred. Maintaining adequate water flow with a filter or spray bar is crucial, alongside regular 10-20% water changes to prevent the accumulation of organic waste.

Behaviour

African Darter Characins thrive in peaceful community setups with species that share similar habitat preferences. While they may display territorial behavior, keeping them in groups with ample hiding spaces can mitigate any potential aggression. Observing the interactions between individuals is a fascinating aspect of their behavior, adding to the allure of owning these fish.

Feeding and Diet

In their natural habitat, these characins primarily feed on benthic invertebrates, which can be supplemented in aquariums with small live or frozen foods like bloodworms and Daphnia. Most specimens do not readily accept dry food alternatives, making a diet rich in live or frozen foods essential for their health and well-being.

Reproduction & Dimorphism

As of now, successful reproduction of African Darter Characins in captivity has not been documented, and sexual dimorphism remains unknown. Further research and breeding efforts may be necessary to uncover insights into their reproductive behavior and potential physical differences between males and females.

Habitat and Distribution

Endemic to parts of the River Congo basin in the Democratic Republic of Congo, the African Darter Characin is typically found in swiftly-flowing sections of rivers and streams. These fish seek shelter among rocky substrates and marginal vegetation in their natural habitat, highlighting their preference for dynamic aquatic environments.
