Be careful when maintaining your aquarium or trying to fish catfish. The first rays of the dorsal and pectoral fins are sharp spines that can cause injury. As part of the mucus on the integument of the body, there are toxins that enter the wound when injected. For this reason, a prick with such a thorn is quite painful and comparable to a bee or wasp sting. Possible acute pain, swelling at the injection site and a sensation of pulsation.
Outwardly, the catfish resembles another closely related species - Pimelodus painted, but the latter is noticeably smaller, and the specks in the body drawing are of an irregular shape and are not so evenly located.

Plants are selected from hardy and unpretentious species such as Java fern, Anubias, etc.
For long-term maintenance of Pimelodus spotted, it is important to provide clean water and keep the pH and dGH values within an acceptable range. The catfish are sensitive to the build-up of organic waste. The aquarium should be maintained regularly and the filtration system should be running smoothly.
In nature, aquatic invertebrates form the basis of the diet. In a home aquarium, it will accept both popular dry sinking food (flakes, granules) and fresh or frozen foods, for example, bloodworms, earthworms, pieces of shrimp meat, mussels. On occasion, eat small fish, fry.
