Datasheet

General Description

Ctenolucius Hujeta, commonly known as the Gar 'Characin', is a predatory fish indigenous to South America. Belonging to the family Ctenoluciidae, it is distinguishable by its elongated body, tapering shape, and small teeth with curved tips. With a maximum size of 25.0cm, it is a popular choice among hobbyists due to its adaptability and manageable adult size.

Aquarium Setup

When setting up an aquarium for the Gar 'Characin', it is crucial to provide surface cover such as floating or overhanging vegetation. Decor elements can include a sandy substrate, leaf litter, driftwood branches, twisted roots, and plants like Microsorum or Anubias spp. Lighting should suit the plant species chosen. A tightly-fitting cover is essential as these fish are proficient jumpers. Efficient filtration, through external canister filters or a sump system, is necessary due to the species' waste production. Regular 30-50% water changes are vital to prevent sensitivity to organic pollutants.

Behaviour

Surprisingly peaceful with larger tank mates, the Gar 'Characin' can thrive in community tanks if paired with placid species such as certain catfish and characids. They are not aggressive towards their own kind, with juveniles displaying schooling behavior. While older individuals tend to be more solitary, it is best kept in groups of four or more to maintain their social interaction.

Feeding and Diet

As obligate predators, Ctenolucius Hujeta primarily feeds on smaller fish and insects in the wild. In captivity, they can adapt to a diet of bloodworm, prawns, mussels, and various live or dead alternatives. Care should be taken not to overfeed, avoiding mammalian or avian meat which can lead to health issues. Feeding them a varied diet with proper nutritional value is key to their well-being.

Reproduction & Dimorphism

Limited information is available on the reproduction of the Gar 'Characin'. Successful spawning involves courtship behavior between males and females, culminating in the release of eggs and milt at the water's surface. The fry require small live foods for initial sustenance. Sexually mature females are slightly larger and rounder-bodied, while males exhibit thicker anal-fin rays and a larger fin size.

Habitat and Distribution

In the wild, Ctenolucius Hujeta is found in South America, ranging from Venezuela to Colombia in various river drainages. They prefer hunting at the water's surface near vegetation and calmer waters. The species possesses modified lip membranes for breathing in oxygen-deficient conditions, adapting to seasonal habitat changes. Their natural range reflects a preference for specific aquatic environments in the region.
