Finally, the Wels catfish is not afraid of hunting bigger animals like birds, rats, and mice. It can swim up to the surface and catch birds resting by the water. Sometimes, it slips onto land and catches small mammals that live near the water’s edge. These bigger meals are not as common, but they still help the catfish survive and grow.

The Wels catfish is not a picky eater. It hunts and eats smaller fishes, frogs, birds, and even mammals like rats and mice. With its sharp teeth and patient waiting, the catfish is a skilled predator that can adapt to different food sources in its habitat.

Locomotion of Wels Catfish

Wels catfish, a large freshwater fish, moves in a unique way called locomotion. The catfish has a long and slim body, which helps it to propel through the water effortlessly. It uses its strong, muscular tail to sway from side to side, pushing itself forward. This tail movement enables the catfish to swim with speed and agility, allowing it to catch prey and escape from predators.

Another fascinating feature of Welsh catfish locomotion is its ability to create suction. When it wants to eat, the catfish opens its mouth wide and rapidly expands its gills, creating a vacuum-like effect. This suction pulls the food towards the fish’s mouth, making it easier for the catfish to consume its meal. The combination of its strong tail and suction power helps the Welsh catfish survive and thrive in its watery home.

Social and Sexual Behaviour of Wels Catfish

Wels catfish, a type of large freshwater fish, have interesting and unique social and sexual behaviours. These fish are known to form groups referred to as schools or shoals. In these groups, they swim together and communicate with each other using sounds and vibrations. Being in a school provides them with safety and increases their chances of finding food.

When it comes to their sexual behaviour, Wels catfish have an intriguing strategy. Unlike many other fish species, the males don’t build nests or protect the eggs. Instead, during the breeding season, the female lays her eggs in a secluded area, such as a burrow or a hollow log. After she lays the eggs, the male comes and fertilizes them, but he does not stick around to take care of them. The female is responsible for guarding and protecting the eggs until they hatch.

After the eggs hatch, the young Wels catfish begin their independent lives. They are born with an instinct to find shelter and food. As they grow, they may join other young catfish, forming their groups. This behaviour contributes to their survival and helps them learn important skills from one another.

Wels catfish are social creatures that form groups for safety and communication purposes.
