This fish is known for its unique appearance, with a flattened body and a head that is slightly flattened, giving the Otocinclus lateral vision.

The Dwarf Suckermouth Catfish is a peaceful species, making it a good choice for community tanks. They prefer to swim at the bottom levels of the tank, often hiding among plants and other decorations. They are not known to be aggressive towards other fish species, making them compatible with a variety of tank mates. Ideal tank mates for the Dwarf Suckermouth Catfish include small tetras, rasboras, peaceful barbs, danios, corys, shrimp and livebearers, and pencilfish. While larger, more aggressive species should be avoided. This species is not known to be a schooling fish, but they can be in groups of 3 to 6 provided the aquarium is large enough.
When it comes to their diet, the Dwarf Suckermouth Catfish is an herbivore. They feed mainly on algae, so a tank with a lush growth of algae is ideal for them. However, their diet should be supplemented with other foods such as algae wafers, green flakes, and blanched vegetables. Removing any uneaten vegetable matter from the tank within 12 hours is important to maintain water quality.
The ideal tank habitat for the Dwarf Suckermouth Catfish includes a dark substrate, dense areas of plants, and rocky caves to retreat in. Live plants, smooth rocks, and caves are also appreciated for providing cover. Broadleaf plants such as Java Fern, Anubias, Amazon Sword, Nomaphila Siamensis, and Ludwigia make excellent choices for Dwarf Suckermouth Catfish. Bright lighting is recommended to encourage abundant algal growth, which will provide some nourishment for the fish.
The water parameters for this species include a minimum aquarium size of 10 gallons, with an ideal community aquarium size of 20 gallons or more. The water should have a pH of 6.0-7.5, a hardness of 6-15 dGH, and a temperature of 70-78°F (21-26°C).
