Can they be kept with other fish?

They are peaceful and rarely bother other fish, making them well suited to community tanks with species that prefer similar water conditions.

Is this species subject to CITES?

Zebra Otocinclus

The Zebra Otocinclus is a small algae-eating catfish known from a single river system in Peru, easily recognized by the bold black-and-white stripes running along its slender body. Reaching only about 4 to 5 cm as an adult, it spends its days quietly grazing on algae and biofilm rather than drawing attention to itself. Peaceful by nature, it rarely bothers other fish and fits comfortably into community tanks. However, because it depends heavily on algae and biofilm that only build up once a tank has matured, newly set-up aquariums often can't offer enough food, leaving it prone to starvation. For this reason, it's generally regarded as a fish for experienced keepers who can judge whether a tank is truly ready.

About Zebra Otocinclus

Zebra Otocinclus is a small, striped algae-eating catfish from Peru that thrives on algae and biofilm in mature tanks. Best suited to experienced keepers with well-established aquariums.

7 things to know before welcoming a Zebra Otocinclus

1Wait for tank maturity
Zebra Otocinclus rely mainly on the algae and biofilm that build up naturally in an aquarium. A newly set-up tank has too little of this food source, which can lead to starvation, so wait until the tank is well established before adding them.
2A species for experienced keepers
This species is considered suited to experienced aquarists. Securing enough food and managing water quality both take some know-how, so prior experience with otocinclus or other small fish is recommended before taking one on.
3Adults reach about 4-5cm
Even fully grown, this fish stays a compact 4 to 5 cm, making it manageable without a large tank. Still, consider the size of any tankmates when planning a community setup.
4Bold black-and-white stripes
Its slender body is marked with distinctive black-and-white blotches running lengthwise. A small group swimming together adds a unique visual accent to the tank.
5Peaceful and community-friendly
Zebra Otocinclus are peaceful and rarely bother other fish. They generally do well alongside species that prefer similar water conditions.
6Supplement their diet
Algae alone may not always be enough to keep them fed. During periods when algae is scarce, supplement their diet with algae wafers or blanched vegetables.
7Found in only one river system
This fish is known from just a single river system in Peru. Keeping its native habitat in mind, avoid sudden changes in water conditions.
