Expert Answer
The plecostomus is an omnivorous fish that mainly eats bottom organic waste, including rotting plant leaves, plankton, and small mollusks. It lives at the bottom, foraging on the river or tank bed.
Because of its diet, it plays an important role in cleaning the water and nutrient cycling, helping maintain ecological balance.
