Otocinclus

In mature planted setups, Otocinclus adds light cleanup support without changing the peaceful feel of the tank.

Otocinclus is best added to a mature, stable aquarium with visible biofilm, gentle algae growth, and established plant surfaces. It is one of the better small aquarium fish for hobbyists who want a peaceful cleanup helper without jumping to large plecos.
