Ecology
P. cataphractus is abundant in calm waters of swamps and mangroves. Omnivorous, they feed mainly on detritus; these fish search for food by digging in the sediment. They are nocturnal; during the day, they lie hidden in the underwater roots and stocks. The spiny catfish is able to produce sounds; every basic unit of the sound they emit when they move their pectoral spine lasts 100-200 milliseconds and has a frequency of 170-250 hertz.
