Masked julie (Julidochromis transcriptus ) – the smallest representative of the species of casseroles.

Occurrence

Africa. Endemic species, inhabiting only coastal areas in the northwestern part of Lake Tanganyika. There are many varieties of this species named depending on their geographic origin, eg Gombe, Bemba, Korosha, Luhanga, Kissi, Kapampa, Kalemie. Found between rocks at depths from 5 to 24 m.

Characteristics and disposition

The shape of the body is elongated and cylindrical with thick, soft lips. White-gray to yellow-brown coloration. There are three rows of dark spots running along the trunk, forming vertical stripes. The pectoral fins are yellow, and the odd ones are dark, blue-rimmed. Sexual dimorphism is poorly visible .

Sex differentiation possible only during spawning. The female is slightly larger and more rounded. The male shows a pointed nipple. Active and quite tolerant fish prefer to stay in the lower parts of the reservoir. Stubborn – they do not change the area once chosen.

They create multigenerational communities. The casings are characterized by a specific way of belly swimming parallel to the surface along which they are moving. While swimming along the vertical walls, they take a vertical position, while while moving under the rock vault, they are turned upside down. Hidden among vertical rock folds, they freeze without moving, making the impression that they are stuck to a stone wall.

Nutrition and feeding

Omnivorous.

In nature, they feed on plankton and small invertebrates found among algae. It is best to give live and frozen foods, supplemented with dry and plant foods.

Aquarium

It is recommended to keep steam in an approx. 80-liter aquarium, with numerous rock decorations, sandy ground and not too bright lighting. Water should be well oxygenated.

They do not tolerate changes in the design of the reservoir and large water changes . If there is a need for a larger substitution, it is best to carry out several smaller substitutions (10%) at intervals of several days. These fish do not damage plants. They can be kept in a social aquarium with other peaceful fish with similar environmental requirements. In a sufficiently large tank, good company will be e.g.

Trophies, Princesses ( Neolamprologus ), Altolamprologus. In smaller aquariums, you should avoid fish that cover similar territories, and fish, if you think about breeding them.

Breeding

Easy but requiring patience. It is recommended that you buy a group (6-10) of young fish and allow them to mate naturally. This process is long and may take about a year or more.

After pairing the fish, it is best to transfer the rest of the fish to a separate tank. The casings stay together for life. Rush (buying an adult male and female) is not recommended and is often doomed to failure. The aquarium should have a minimum size of about 80 liters, furnished as described above. The optimal water parameters are the pH of about 8.2-9.0 and the temperature of 26 ° C.

Cashews reproduce in hiding from the aquarist’s eyesight. It multiplies between the recesses of the rocks. The female lays around 100 eggs (but usually less) on the bottom or roof of the cave. We usually find out about the enlargement of the family only when the young leave the grotto. Both parents take care of the offspring evenly.

Fry up to 2.5 cm long remain near the nest and help to care for the next generation and guard the nest. Larger specimens are chased away. The young are immediately fed with artemia, brine shrimp larvae or other small foods.
