Zebra Oto, Otocinclus cocama

The Zebra Oto (Otocinclus cocama) is a fish from Peru. This fish is from the genus Otocinclus and is a family member of Loricariidae.

In 2004, a tributary of the Rio Ucayali in Peru described the Zebra Oto. Relatives close to the Zebra Oto are O. mariae, O. huaorani, O. bororo, O. mura as well as the O. batmani.

This fish is found in the Ucayali River in Peru and likely in the Maranon River. This fish is also found in clear water and mid-sized creeks. The Zebra Oto associate with marginal vegetation.

The Zebra Oto exhibits a body shape similar to other Otocinclus. It has armor on its body and is small with a suckermouth.

Because of the vertical stripe-like blotch and the lateral line, the Zebra Oto is easily distinguished from other members of this genus. Out of any of the Otocinclus speices, the Zebra Oto has the most teeth. The Zebra Oto, along with the O. batmani, are the only fish in the geus distinguished a W mark on its caudal fin. The male Zebra Oto is smaller then the female Zebra Oto which can reach about 1.7 inches.

Since the 1990s the Zebra Oto has been for sale in the aquarium trade, and has been popular since 2000. This fish is sporadically seen and is bred in large numbers in Asia.
