Which coloration details aid in the camouflage of *Clarias batrachus* in its preferred habitats?
Dark brown to grayish or black
The typical coloration of the walking catfish serves as effective camouflage within the murky or muddy environments it favors in the wild. The primary shade ranges from dark brown, extending into grayish or black tones. This dark pigmentation helps the fish blend seamlessly with silty riverbeds and darkened bottoms. It is important to recognize that this coloration is not entirely rigid; variations can occur, sometimes manifesting as lighter sides or mottled patterns. Furthermore, individuals housed in artificial captivity, lacking natural substrate, may display duller colors compared to their wild counterparts who require precise matching to their natural substrate.
