Distribution and habitat
The distribution area of the Common Bearded Catfish is the inlet of the Rio Cuiaba in Brazil. Their coloration and pattern is very variable. They live in jungle streams and rivers, prefers in the current between stones and dead wood and roots that protrude into the water.
Maintenance
The aquarium should have a loose planting, with stones as well as roots, which serve as a hiding place and at the same time are part of their diet. A substrate of round gravel, sufficient swimming space and oxygen-rich water with 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 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 are diurnal fish. Several Common Bearded Catfish should always be kept together. They are very peaceful within the species and towards other fish and can be socialized well with other calm fish
Basically, only compatible fish species with similar demands on water quality and water temperature should be socialized.
Sex dimorphism
Sexually mature males have bristles on both sides of the head.
Reproduction and breeding
There are no known reports of successful breeding in the aquarium.
Important
They can also scrape off wood with their powerful sucking mouths, and they have intestinal flora that allows the fish to digest the cellulose
When catching them, use the finest mesh nets possible so that the hard rays of the pectoral fins or the skin teeth (odontodes) do not get 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.
