The nickname of “talking catfish” comes from the ability of the fish to produce sounds when dealing with conspecifics or when threatened. It can reproduce these sounds in two ways.
The first includes a partial blockage of the pectoral fins in their grooves, rubbing spines, creating a “buzzing” sound. Secondly, by quickly contracting and relaxing the muscle that is attached to the back of the skull at one end and the front of the swim bladder at the other.
This leads to the fact that the swim bladder at the same time resonates and makes a somewhat deeper and louder sound. The sounds are clearly audible, and they can sometimes be heard through aquarium glass, or when the fish is in the net. Use caution when catching these catfish, as the spikes on the body and fins can easily become entangled in the net net.
