Catfish is a breed that has almost 3000 species of its own with a wide range of sizes from 1.5 inches to a maximum of 177 inches. Most of the catfish can be spotted at the mouth of the river as they require less amount of oxygen. On the contrary, sometimes when the water has less amount of dissolved oxygen, a few other species of this fish swim to the surface of the water and gulp the air and oxygen with their mouth too.
A catfish's dorsal and pectoral spines consist of venom that helps them to protect themselves from danger. When sensing danger, they might bite a human finger or even snap at the hand while being caught. Hence they can be hurtful to humans. If one wants to keep them as a pet, the water requirements would be around 70F to 80F as they thrive to live in warmer water.
