Histoire de nomenclature:

  • Julidochromis dickfeldi, Staeck, 1975:981, combinaison originale

Répartition par pays:

Nom commun: Dickfeld's Julie (US).

Diagnose: The nose is more pointed, there is a blue sheen over the body, and a distinct pattern in the dorsal and caudal fins.

Taille: males 4" (10 cm) females 3" (7 cm).

Dimorphisme sexuel: Dickfeldi is difficult to sex by coloration but typically the males are larger then females.

Localité type: Sumbu National Park region, Lake Tanganyika, Zambia.

Distribution: Endemic to Lake Tanganyika, and only found in the South West part of the lake, between Kapampa and Ndole (Konings, 1998).

Localités: Cape Kachese (Zambie, indigène), Chimba (Zambie, non défini), Katete (Zambie, indigène), Moliro (République Démocratique du Congo, indigène).

Biotope: They prefer the rocky habitat, and found at depths of 5 - 20 meters, temperature between 23 - 27 degrees C., 7.8- 9.5 pH, water very hard that is highly oxygenated, algae is the only vegetation present. (Konings, 2002).

Alimentation: They are consistently listed with a diet of invertebrates, but also eat small snails. Algae is also ingested as they are picking foods off the rocky habitat and sponges. (Konings, 1998).

Reproduction: Breed year round, a cave brooder that produces small clutches of fry, numbering around 35 - 50. Bi-parental care of eggs and fry until it is time to spawn again, and the fry are gently pushed away from the breeding area.

Maintenance: Raise the juveniles in larger community tanks, of 220 liters (60 gallons) or more, with other Tanganyikan Cichlids around the same size. Allowing them to pair off naturally, confirmed pairs can then be removed to a smaller aquariums for breeding purposes. Pairs are easily housed in 40 - 80 liters (10 - 20 gallon) tanks, as the fry rearing and fry removal is more efficient in smaller aquaria. Fry and adults do well on freshly hatched baby brine shrimp, and a cichlid staple flake or pellet. Water changes should be frequent, and a pH of 8.5 or higher is best.

Conservation: Julidochromis dickfeldi est évalué par l'Union Internationale pour la Conservation de la Nature dans la Liste Rouge des espèces menacées comme étant (LC) Peu menacée (2006). The habitat is stable at the moment.

Commentaires: Is Julidochromis dickfeldi really a Julie? They are only found in the rocky habitat in the southwest part of the lake, and feed like Chalinochromis popelini. It has a different body shape from the other Julies, with more of a pointed nose. It has a wonderful blue sheen in the body as well as blue fringing on the dorsal and tail. The dorsal fin appears larger than in the other Julies while the 3 horizontal stripes are more intense than in ornatus. Dickfeldi seem to fall in between the giants Julies (J. regani and J. marlieri) and the dwarf Julies (J. transcriptus and J. ornatus) and usually are around 10 cm. (4 inches), the males are typically larger than females.
