Otocinclus vittatus[1] is a species of catfish in the family Loricariidae.
[2] The common otocinclus is typically sold as an algae eater.
It will rasp most kinds of algae from leaves, hard scape and glass.
Unlike many fish sold under this label, this otocinclus is voracious and can starve if not given proper supplementary feedings after stripping an aquarium of all its preferred foods.
It should be kept in numbers, and will easily become stressed if kept without a sufficiently large school.
