Corydoras catfish are among the most popular aquarium cleaners. These small bottom-dwelling fish constantly search the substrate for food. Using their whisker-like barbels, they locate tiny scraps, worms, and organic debris hidden in the gravel or sand. Groups of corydoras often move together, gently shuffling along the bottom of the tank like tiny underwater vacuum cleaners.
Still, they cannot survive only on leftovers. Experts recommend feeding them sinking wafers, frozen foods, or specialised bottom-feeder diets to keep them healthy. Corydoras are peaceful and thrive in groups, which makes them ideal for community aquariums.
