Like virtually all catfish, it is nocturnal, preferring to feed at night, although young feed during the day. It generally does not get as large as the channel or blue catfish, with average adult weights are in the 1-to-2-pound (0.45 to 0.91 kg) range, and almost never as large as 4 pounds (1.8 kg). It has a typical length of 6–14 inches (15 ...
The wels relies largely on hearing and smell for hunting prey (owing to its sensitive Weberian apparatus and chemoreceptors), although like many other catfish, the species exhibits a tapetum lucidum, providing its eyes with a degree of sensitivity at night, when the species is most active.
Catfish are found in a variety of habitats, from lakes or murky ponds to drainage ditches. They are scarce during the day, but come out at night to feed, searching the bottom of a lake or river for food. [13] They eat insects, leeches, snails, fish, clams, and many plants. They are also known to eat corn, which can be used as bait.

The African butter catfish has a compressed body and an adipose fin is always present. [5] It can grow up to 40 centimetres (16 in) TL and has reported up to a maximum weight of 250 grams (8.8 oz). [5] It is a brownish color on the head and the dorsal surface of the fish, and silvery-white on the underside. [3] The fins are usually colorless.
Most active at night, it feeds on any available food, including invertebrates and insects when small, then fish and other small vertebrates when large. It scavenges off large carcasses and offal from riverside villages. It can live for 12 or more years. [2] The vundu can survive out of water for extensive periods of time. [4]
White catfish feed mostly on the bottom, where they eat other fish and aquatic insects. They feed most actively at dusk and through the night [ 5 ] mostly on bottom-dwelling insects, worms, amphipods, and other small invertebrates.
