Distribution and habitat

The distribution area of the crepuscular and nocturnal Jewel Beard Catfish is the catchment area of the Congo River (Democratic Republic of the Congo, Republic of the Congo, Cameroon). There they live in slowly flowing stream sections of rivers as well as in floodplains, where they usually stay hidden under roots or in stone caves during the day.

Maintenance

The aquarium should have a good border planting with many hiding places between stone structures (e.g. perforated rock) and roots as well as offer sufficient swimming space. A dark sand substrate, shaded light (floating plants) and a weak current is ideal.

No ammonia, ammonium and nitrite should be detectable, the nitrate value should not exceed 100 mg/l. To ensure the water quality and oxygen content, a filter and heater adapted to the aquarium size is required, as well as lighting for the species-appropriate day-night rhythm of the animals.

Diet

They are easy to feed and will accept any type of live or frozen food, such as daphnia, cyclops, mysis, artemia and black mosquito larvae, as well as sinking dry catfish food (granules, pellets, tablets). In addition, they need regular vegetable food, such as crushed peas, cucumber slices, pureed leafy and wild vegetables or dry food with high vegetable content (spirulina, kelp)

Only feed as much as will be eaten in a few minutes. A regular and varied diet promotes health and increases resistance.

Behaviour and compatibility

These peaceful fish should be kept in a group of at least 4 animals. In tanks that are too small, intraspecific incompatibilities can occur with adult animals. A group should only be kept in a larger and richly structured tank. They can be well socialized with other, not too small fish, such as cichlids, barbs or catfish.

Basically, only compatible fish species with similar demands on water condition and water temperature should be socialized.

Sex dimorphism

Adult males are slightly darker in color than the slightly larger females. With some experience, the sexes of adults can be determined by the shape of the genital papilla, which is pointed in the male and round in the female.

Reproduction and breeding

There are no known reports of successful breeding in the aquarium.

Important

They usually stay in caves or under roots during the day, often hiding with their belly up. In shaded aquariums, however, they are also active during the day and come out of hiding especially for feeding

When catching them, use as fine-meshed nets as possible so that the hard rays of the pectoral and dorsal fins do not get caught, which can cause painful stinging injuries when touched.

The well-being of the fish should be checked regularly. Temperature should be checked daily, pH, hardness and nitrate levels at least every 14 days. Regular partial water changes are recommended, even when contaminant levels have not yet reached the upper limit. Sudden changes in water quality should be avoided. Newly introduced fish must be accustomed slowly to the water in the aquarium.
