Otocinclus Catfish, commonly known as “Otos,” are among the best and safest algae-eating fish available for planted aquariums. These small, peaceful suckermouth catfish are famous for their ability to clean algae from glass, plant leaves, and hardscape without causing any damage to delicate aquatic plants.
