Cyprinodon Julimes

Datasheet

General Description

The Julimes Pupfish, scientifically known as Cyprinodon Julimes, stands out from its nearest relatives with distinct combinations of characteristics related to its standard length and head length. Its habitat is exclusively confined to the geothermal spring called 'El Pandeño de los Pando' in Chihuahua state, northern Mexico, with unique environmental conditions.

Aquarium Setup

For a tank housing the Julimes Pupfish, a capacity of at least 60 liters is recommended. The setup should prioritize multiple hiding spots to break lines of sight, achieved through aquatic plants and wool mops. Sponge-type filtration units are preferred to ensure the safety of eggs and fry. Although lighting is not a crucial factor, it can be utilized, and the growth of filamentous algae is beneficial when feasible.

Behaviour

The behaviour of the Julimes Pupfish in an aquarium setting is likely influenced by its natural instincts acquired from its habitat in the geothermal spring. Observing their interactions within the tank, especially regarding territorial behavior and hierarchy establishment, can provide insights into their social dynamics.

Feeding and Diet

In their natural habitat, Julimes Pupfish have been observed consuming diatoms, cyanobacteria, and small invertebrates. When kept in aquariums, providing a diet that mimics these natural food sources is crucial for their nutritional needs and overall health. Supplementing their diet with high-quality commercial fish food may also be necessary to ensure a balanced nutritional intake.

Reproduction & Dimorphism

Details about the reproductive behavior and potential dimorphism of the Julimes Pupfish can be observed in a captive aquarium environment. Monitoring their spawning habits, courting rituals, and any physical distinctions between males and females can offer valuable insights into their breeding dynamics and potential sexual dimorphism.

Habitat and Distribution

The Julimes Pupfish, endemic to the municipality of Julimes in Chihuahua state, northern Mexico, exclusively inhabits the geothermal spring known as 'El Pandeño de los Pando.' This unique habitat features fluctuating water temperatures between 38-48°C (100.4-118.4°F) and is considered one of the hottest fish-inhabited environments globally, providing a specialized ecosystem for this species.
