Oto Catfish

Otocinclus Catfish

The Oto is a dwarf suckermouth catfish and is a popular freshwater aquarium fish known for its ability to keep algae buildup under control. It is timid peaceful fish that is very active and should be kept in a small group of no less than 4 fish, being in a group makes them feel safe and become more active. It is not a colorful fish but an intriguing one, it is continuously foraging and looking for food all around every leaf and small spaces where there is organic biofilm to feed on. Otocinclus should be added to a cycled stable and established planted aquarium. They grow to a maximum size of 2 inches but mostly they are a little smaller 1" or so. In the wild, they inhabit South America rain forest waterways that have lots of vegetation. They do well in soft/med water, Hardness,  pH 6.8-7.5, temp 72-80 F

Environment Otocinclus Catfish

Otocinclus catfish are commonly found in slow-flowing shallow rivers and streams in South America. In their wild habitat, the fish attach themselves to rocks, driftwood, and other stable surfaces to feed off algae. The waters in this habitat are moderately-vegetated, with good access to sunlight and a soft, sandy riverbed.

Feeding Otocinclus Catfish

In the wild, Oto catfish are herbivorous and eat a diet that largely consists of algae, bacteria, and plant matter. Providing a plentiful source of algae in the tank is the best way to replicate the fish’s diet in captivity. Good Quality sinking food like Dr. Bassleer Biofish Food or Northfin Kelp wafers is a great choice. Most high-quality sinking food will be fine. Other tankmates for Otos can be guppies, most community fish like tetras, Angelfish or Rams. Check out other fish for sale at Michaels Fish Room here. Otos do best in a group of 6 or more. They are great for the community fish tank as they are peaceful and will help keep the algea at bay. They do well with livebearers, plecos, tetras, and most other peaceful fish.
