Dwarf Oto is a genus of catfish in the family Loricariidae native to South America which are commonly called “dwarf suckers” or “otos”. This genus, like other loricariids is characterized by rows of armour plating covering the body, as well as the underslung suckermouth.

Featuring a tan with a black peppered body, the Otocinclus Catfish is an attractive and functional addition to any freshwater aquarium. Originating from fast-moving rivers in South America, the Otocinclus Catfish should be housed in at least a 10-gallon aquarium with high filtration, good water movement, and high aeration. A planted aquarium with rocks and driftwood will provide plenty of hiding spaces to prevent the Otocinclus Catfish from becoming stressed. As a peaceful and very social fish, the Otocinclus Catfish prefers to be kept in small schools. Otos will mainly graze on some soft algaes, primarily diatoms, and blanched vegetables such as Zucchini (Courgette), Carrot, Potato and Cucumber.
