Otocinclus Catfish (Oto Fish) – Peaceful Nano Algae Eater

Otocinclus catfish are one of the best algae-eating fish for small aquariums. These peaceful nano fish stay small, typically reaching around 1.5–2 inches, making them ideal for planted tanks and community setups.

Known for their gentle temperament and constant grazing behavior, Otocinclus help keep algae under control while adding natural movement to your aquarium. They thrive in groups and do best in well-established tanks with plenty of biofilm and plant coverage.

At Razz Aquatics, our Otocinclus catfish are carefully sourced and shipped with care to ensure they arrive healthy and ready to thrive in your aquarium.
