Distribution and habitat

The distribution area of the Para River Tortoiseshell Catfish L163 is the Rio Para in Para, Brazil. They often stay in river sections with stones and dead wood.


The aquarium should have a robust planting, with stones and caves (catfish burrows) and roots that provide hiding places and at the same time are part of their diet. A round-grained substrate, subdued light (floating plants) and a weak current are 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.


They feed on plant and animal food. 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, scalded spinach, as well as zoopankton, cyclops, daphnia, artemia, mosquito larvae, shrimp, 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

Para-trunked catfish are crepuscular and nocturnal. They sometimes behave intra-species territorial, so multiple 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

Sexually mature males possess significantly longer gill cover spines (interopercular odontodes) than females.

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.


The Para-frog catfish L163 is often confused with the L13. There are different opinions whether they belong to the genus Ancistomus or Peckoltia

When catching, use the finest mesh nets possible to avoid snagging the hard rays of the pectoral fins or the skin teeth (odontodes) 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.
