Wetlands are low lands where water logging is caused by regular rain. Fish grows normally in these wetlands and are active throughout the day, running and searching for food. Naturally growing grasses in the wetlands are stirred by gusty winds. In turn, hanging leaves of grasses stir water surface, causing patterns of ripples. Because of shadows of leaves and random reflection of sunlight on water surface, dark to golden light effects are created along the ripple patterns and on soil bed.
