Julidochromis Transcriptus

Datasheet

General Description

The Masked Julie (Julidochromis transcriptus) is a species of cichlid belonging to the order Perciformes and the family Cichlidae. Endemic to northwestern Lake Tanganyika, specifically between Luhanga and Makabola in the Democratic Republic of the Congo, this species has its type locality noted as the 'extreme north' of the lake. The etymology of its scientific name derives from the putative tribe Julidini and the Greek term 'chromis,' meaning 'fish,' along with the Latin 'transcribo,' signifying 'transcribed' or 'copied.'

Aquarium Setup

When housing a Masked Julie in an aquarium setting, it is crucial to replicate its natural habitat to ensure its well-being. Typically found in rocky, coastal zones, providing ample hiding spots, rocks, and caves are essential. These fish prefer a moderately large tank with ample swimming space and a sandy substrate (see table for specifics). Aquatic plants, while not a necessity, can be included to mimic the natural environment of the Masked Julie.

Behaviour

The Masked Julie is known for its relatively peaceful demeanor compared to other cichlid species, making it suitable for community tanks. However, they can become territorial during breeding periods. These fish exhibit typical cichlid behavior, showing hierarchy within the tank. They are agile swimmers and often dart in and out of rocky crevices.

Feeding and Diet

In the wild, Masked Julies primarily feed on small invertebrates, crustaceans, and zooplankton. When kept in captivity, they readily accept high-quality cichlid pellets, flakes, live, or frozen foods such as bloodworms, brine shrimp, and daphnia. Providing a varied diet will help ensure their optimal health and vibrant colors.

Reproduction & Dimorphism

Masked Julies are biparental substrate spawners, meaning both parents are actively involved in caring for their fry. Prior to spawning, they exhibit typical cichlid breeding behaviors, including cleaning a selected rock surface for egg deposition. Males and females can be distinguished by subtle differences in size and coloration, with females typically being slightly larger and rounder in appearance.

Habitat and Distribution

This species is endemic to northwestern Lake Tanganyika, specifically inhabiting the rocky, coastal zones between Luhanga and Makabola in the Democratic Republic of the Congo. Their natural habitat consists of areas with rocky structures, providing ample hiding places and breeding sites. The Masked Julie is a fascinating species to observe in its native freshwater habitat, displaying unique behaviors and interactions within its environment.
