Species Profiles
Otocinclus Catfish
Otocinclus spp.
Otocinclus catfish (otos) are tiny, peaceful algae eaters that are incredibly effective at controlling soft green algae and diatoms in planted tanks. They are the gold standard for planted tank algae control, often preferred over larger plecos. However, they are somewhat delicate and require established, well-maintained aquariums.
