Narcissus Minnows are native to the freshwater systems of Australia, including rivers, streams, and ponds. They can be found in a variety of habitats, from clear waters to muddy bottoms, and are known for their adaptability.

Aquarium Habitat

When kept in captivity, Narcissus Minnows require a well-maintained aquarium that mimics their natural habitat. A planted tank with plenty of hiding places is ideal, as these fish enjoy exploring and burrowing in substrate.

Tank Mates

Narcissus Minnows are generally peaceful fish and can be kept with other community species, like tetras or guppies. However, they should not be housed with larger or aggressive fish, as they may become stressed or injured.

Water Conditions

Breeding and Reproduction

Courting Behavior

During breeding season, male Narcissus Minnows will display their bright green coloration and engage in elaborate courting displays to attract females. They may also engage in "head-butting" behavior to establish dominance over other males.

Spawning

Once a pair has formed, the female will lay her eggs in a carefully constructed nest that the male has prepared. The eggs will hatch in about 4-6 days, depending on water temperature.

Fry Care

After hatching, the fry will consume their egg sacs for nutrition before moving on to small live foods like brine shrimp or microworms. They require careful monitoring and feeding to ensure their survival.

Care and Maintenance

Narcissus Minnows are omnivorous and require a varied diet that includes both protein-rich foods like bloodworms or brine shrimp and plant matter like spirulina flakes or algae wafers. It's important to ensure they receive a balanced diet to maintain their health and vitality.

Aquarium Setup

When setting up an aquarium for Narcissus Minnows, it's important to provide plenty of hiding places like rocks, caves, or plants so they can explore and feel secure. A substrate of fine sand or gravel is ideal, as these fish enjoy burrowing.
