2. Catfish's living habits

1. Catfish mainly live in the middle and lower layers of lakes, rivers, reservoirs, and ponds, and mostly move in coastal areas. They are ferocious bottom fish, afraid of light, and like to live in deep pits near the banks of rivers, crevices in rocks, soil holes or stone caves at the bottom of tree roots, and waters with slow flow. They start to move and forage in spring, stop eating after winter, and spend the winter lurking in deep water areas or caves.

2. Catfish have small eyes and poor vision. They hide during the day and come out at night. They are very greedy. The hotter the weather, the more they eat. They hunt by sense of smell and two pairs of tentacles. They are active frequently on cloudy days and at night. In the still water of reservoirs, ponds, lakes, and weirs, they often lie in the dark bottom or under patches of water lilies, water peanuts, and water hyacinths.
