Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal, [6] [7] but others (many Auchenipteridae) are crepuscular or diurnal (most Loricariidae or Callichthyidae ...
Electric catfish are found in tropical Africa and the Nile River. [3] Electric catfish are usually nocturnal and carnivorous. [2] Some species feed primarily on other fish, incapacitating their prey with electric discharges, [2] but others are generalist bottom foragers, feeding on things like invertebrates, fish eggs, and detritus.

Driftwood catfishes are nocturnal. Some of the smaller species are known to hide in logs and crevices during the day, and come out to feed at night. Some larger species can consume fruits and insects, and are probably omnivorous.
Within the same laboratory populations of goldfish, some individuals may be spontaneously diurnal while others are nocturnal. [43] Goldfish can also be diurnal if food is more available by day, or nocturnal if food is available at night. [44] Salmon are mostly diurnal when temperature is high, but become more nocturnal if temperature plummets. [45]
Honeycomb catfish like to anchor themselves into crevices in driftwood and hide. They are mostly nocturnal and seek hiding spaces and shade. A very peaceful species, in an aquarium, honeycomb catfish do not bother other inhabitants of a community tank. [2]
Like virtually all catfish, it is nocturnal, preferring to feed at night, although young feed during the day.

It has a typical length of 6–14 inches (15 ...

The wels catfish has also been observed taking advantage of large die-offs of Asian clams to feed on the dead clams at the surface of the water during the daytime. This opportunistic feeding highlights the adaptability of the wels catfish to new food sources, since the species is mainly a nocturnal bottom-feeder. [22]
