Distribution and habitat

The distribution area of the Jauaru Mountain Hare Catfish L412 is the Rio Jauaru, a small river in northeastern Para, Brazil. They stay in the oxygen-rich rapids with stones and dead wood.

Maintenance

The aquarium should have a robust edge planting with large river pebbles, caves (catfish burrows) and roots that provide hiding places and are also part of the food. A round-grained substrate and a strong current are ideal.

No ammonia, ammonium and nitrite should be detectable, and 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 eat the vegetable cover (growth) of stones, wood, plants, etc. and the microorganisms contained therein. For a balanced diet, feed once a day with a high-quality dry food for loricariid catfish (granules, pellets, chips, tablets), supplemented with algae leaves, soft wood and fresh vegetables, such as zucchini, broccoli, bruised peas or scalded spinach, plus occasional small amounts of zooplankton, cyclops, daphnia, artemia, mosquito larvae, etc. (live or frozen)

Feed only as much as will be eaten within a few minutes, excluding plant foods. Regular and varied feeding promotes health and increases resistance.

Behaviour and compatibility

They sometimes behave intra-species territorial, so several animals should be kept only in large and richly structured tanks. They are very peaceful towards other fish and can be socialized well with them.

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

Sex dimorphism

The slightly larger males usually have a more angular head and a pronounced snout margin.

Reproduction and breeding

There are no known reports of successful breeding in the aquarium. They are cave breeders and the male does the brood care.

Important

When trapping, use the finest mesh nets possible to prevent the hard rays of the pectoral fins or the skin teeth (odontodes) from becoming caught on the bone plates, which can cause painful puncture wounds 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.
