Relevant Information:

Usually imported as O. affinis or O. vittatus. The caudal fin design separates it from other Otocinclus species. The upper and lower caudal fin lobes have two rows of vertical semicircles. Some specimens have a small gap between the caudal spot and the band on the caudal peduncle. 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.
