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.

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.
