Live Freshwater Aquarium Bottom Feeder Otocinclus Catfish (Otocinclus vittatus)

Otocinclus Catfish (Otocinclus spp.)

The Otocinclus Catfish, often simply called the "Oto," is one of the most popular and effective algae-eating fish for freshwater aquariums. Small, peaceful, and hardworking, these gentle catfish are highly prized for their ability to graze on soft algae while coexisting harmoniously with community fish, shrimp, and planted aquarium inhabitants.

Otocinclus spend much of their day grazing on aquarium surfaces, including plant leaves, driftwood, rocks, and glass. Their calm temperament and compact size make them an excellent choice for nano tanks, planted aquariums, and community setups where larger algae eaters may not be suitable.

These social fish thrive when kept in groups and are especially appreciated by aquascapers looking for a natural and plant-safe cleanup crew. Their constant activity and algae-grazing behavior help maintain a cleaner and healthier aquarium environment.
