Yes, Otocinclus, fondly termed as ‘Otos,’ are known for their excellent cleaning prowess, even efficiently scrubbing the glass walls of an aquarium. Their small size and natural inclination to graze algae make them perfect candidates for glass cleaning duties. They play an essential role in controlling unwanted algae growth in tanks, making them desirable for aquarium hobbyists.
However, a common misperception is that Otocinclus will survive solely on the algae in an aquarium. In reality, once Otos deplete the natural supply of algae, they should be provided with supplemental feeding. Offering algae wafers, blanched vegetables, and other plant-based diets helps ensure they receive proper nutrition while they keep your aquarium spotless.
