Otocinclus

The Otocinclus, often called the Oto Catfish or Dwarf Sucker, is a small freshwater fish highly valued for its algae-eating abilities. Peaceful and active, it’s a perfect choice for keeping community aquariums clean while adding lively charm to the tank.

These shoaling fish thrive in groups and prefer well-planted aquariums with plenty of surfaces to graze on. Gentle and beginner-friendly, Otocinclus are ideal companions for small to medium peaceful fish species.
