To protect our animals and to ensure they get to our customers healthy, we will only ship orders with Nano Fish via UPS Next Day Air.
Long renowned as the arch nemesis of aquarium algae, the Otocinclus Catfish (Otocinclus macrospilus) has been eradicating tanks of this nuisance for many years. Their sucker-mouths are perfectly equipped to tackle algae from all surfaces of an aquarium.
The “Otto” or “Otto cats” as they are fondly referred to, are native to South America where they reside in fast-flowing bodies of water. As such, they enjoy aquariums with stronger water flow and good aeration. They are not large fish, maxing out around 2 inches in length. Ottos are recognizable by the mottled pattern on their bodies.

I’ve had my Otocinclus for three months now and it’s been a game-changer for my tank. It constantly eats algae without causing any disturbances. The fish is active and stays healthy in my 10-gallon setup with strong flow. Easy to care for and very effective.

The fish arrived quickly and looked healthy. It’s been cleaning the glass and decorations since day one. I didn’t have to worry about algae buildup. Just make sure the tank has good water movement.

I was skeptical at first, but after adding the Otto catfish, my tank has been much cleaner. It doesn’t eat plant leaves or disturb other fish. A small but essential addition to any planted tank.
