Zebra Oto by Imperial Tropicals
The Zebra Oto is a unique and striking variation of the popular oto catfish. Unlike typical otos with solid coloration, this species features black and gray stripes and squiggles along its body. Its white caudal fin, edged with black, adds to its distinctive appearance, making it a visually appealing addition to any aquarium.
Known for being an excellent algae eater, the Zebra Oto helps maintain clean tank conditions, especially when paired with live green plants. This species is native to remote areas of the Amazon and is rarely encountered in the aquarium trade due to its limited availability.
The scientific name Otocinclus cocama honors the Cocama indigenous people who inhabit the same regions. As an endangered species, responsible sourcing and careful tank maintenance are encouraged to support conservation efforts.

The zebra oto is a beautiful addition to my tank. It’s active and helps keep the algae down without being aggressive. The black and white pattern stands out well against the green plants. I’ve noticed it’s more curious than other otos and enjoys exploring the tank. It’s a great choice for someone wanting both function and visual appeal.

I was drawn to this fish because of its unique markings. It’s not common in the trade, and it’s a joy to see. It eats algae efficiently and doesn’t stress other fish. The tank looks more dynamic now with its presence. I appreciate that it’s a species with conservation awareness.

The fish arrived healthy and seems to be adjusting well. It’s active and feeds on algae in the corners. The coloration is exactly as described. A bit shy at first, but now it’s exploring more. Would recommend for planted tanks with a calm environment.
