Relevant Information:

Images 2,3 & 4 are from individuals collected in the Paraná river, Argentina, by Noemí and Haroldo Bishop about 30Km (18.75 Miles) to the North of Diamante City. This locality is named "Valle María". Aquarium care: This is a small group of Loricariids which do well in aquaria and will keep the algae down without harming the plants in the tank. Best to keep in a group with more males for breeding purposes. Breeding: The females will lay eggs on the plants and tank glass after the females have been chased around the tank by the male. Like Corydoras they present a t-position breeding mode. Diet: Omnivore: algae, tablet foods, flake and small frozen foods. Remarks: One of the most common of the Otocinclus species that is imported.
