Catfish - Otocinclus (Otocinclus Arnoldi)

The Otocinclus (or "Oto cat") is a genus of small, peaceful catfish native to South America, highly valued in the aquarium hobby as a natural algae cleaner. They are known for their sucker-like mouths, which they use to graze on algae and biofilm on various surfaces.

Requires live plants, driftwood, and rocks for hiding spots and grazing surfaces. A soft substrate is recommended. Otocinclus are diurnal (active during the day), social, and non-aggressive. They should be kept in groups, or shoals, of at least 3-6 individuals to feel secure.
