Julidochromis dickfeldi (Julidochromis dickfeldi ) – a small aquarium fish from the cichlid family belonging to the fracture group.
Africa. Endemic species , inhabits coastal regions with a rocky bottom in Lake Tanganyika. Found only in shallow waters between Kapampa and the Ndole (south-west part of the lake).
Characteristics and disposition
In an aquarium, it reaches approx.
8 cm in length. In the wild, a little more – 11 cm. Elongated, cylindrical body shape with a high dorsal fin and thick, soft lips. Unlike other Julidochromis, the mouth has a slightly sharper ending. All fins are gray with blue edging.
There are three characteristic dark stripes running along the body. Gender difficult to distinguish . Adult females are slightly larger than males. Dickfeld’s catkins are characterized by a specific swimming, belly parallel to the surface. They assume a vertical position while swimming along vertical walls and belly up under the rock vault.
Hidden among vertical rock bends, they freeze in motion, making the impression that they are stuck to a stone wall. A calm fish showing increased aggression during the breeding period. It creates multi-generational communities – the offspring live in common territory with their parents.
Nutrition and feeding
They are not picky fish and eat most of the available food, only those that are harvested may be reluctant to eat artificial foods . The main component of the diet should be live or frozen foods, less often dry and vegetable foods such as spirulina or chopped spinach.
A pair of Dickfeld’s veins are best kept in an aquarium of at least 80x30x30 in size, with a sandy base, with rock decorations with crevices and caves where the fish will find shelter and lay their eggs. Although plants do not occur in natural habitats, they can be planted in an aquarium. Dickfeld’s aquariums do not tolerate changes in the aquarium well, and you should be careful with water changes. A larger substitution can leave your partner behind. Territorial species.
It can be successfully kept with other small or medium-sized cichlids from Lake Tanganyika, such as Neolamprologus shelldwellers or the Cyprichromis family. Unless we have a sufficiently large tank, they cannot be representatives of Julidochromis . Once chosen by these fish, territories are rarely left by them.
Easy but requires patience. Monogamous species.
Dickfeld’s casings stick together for life. It is recommended to purchase a group of young fish and allow them to pair naturally. This process may take about a year. As soon as steam has formed, the remaining fish should be separated. Buying an adult male and female does not guarantee success – the male often finishes the female.
The spawning tank should be at least 75 cm long, arranged as described above. The optimal water parameters are the pH of about 8.2-9.0 and the temperature of 26 ° C. They reproduce in a fissure or grotto. The female lays about 100 eggs (usually less) on the bottom or roof of the cave. During spawning, the parents are quite active and visible close to the cave, even for a month.
It is often very difficult to say whether breeding has taken place until the young begin to flow out of the nest. Both parents take care of the offspring. The female takes care of the offspring directly, while the male protects the chosen territory from intruders. The fry have a yolk sac and do not need to be fed until they are empty. However, it may happen that we will see them without it, so start feeding immediately.
The young are large enough to accept artemia and brine shrimp larvae.
