Since the catfishes are primarily adapted for nocturnal and turbid water feeding, they catch most of their food items while patrolling at night. During the night many daylight active fish are "resting", "sleeping", or relatively motionless which makes them easy prey for a night adapted predator - similar to the feeding behavior of owls vs hawks. Nature is "full" of animals with unique behavior patterns. It is part of the 'niche' biology concept.
