Otosek lives in South America . It occurs in smaller streams and in densely overgrown, calm rivers in the state of Rio de Janeiro, Brazil.

Characteristics and disposition

Otosek is about 4-5 cm long. Otoski are characterized by dark stripes along the body, a dark spot at the base of the tail, and a mouth that is transformed into a sucker.

Males are slightly smaller and slender than females.

Nutrition and feeding

The main food of the Otoska family is algae. Fish should be fed with green food, small live and frozen food, and dry food in the form of tablets falling to the bottom.


Estuary mites should be kept in an aquarium with a capacity of at least 30 liters, densely covered with plants, with properly selected lighting to ensure sufficient algae growth. These catfish also like numerous hiding places and fine-grained soil.

They feel best in soft water . It should be remembered that these are herd fish, the minimum recommended by breeders is 6 pieces. Otos can be kept with fish of small size, calm disposition and similar environmental requirements, e.g. small cuirass , cichlids .


The reproduction is similar to kirysków.

In contrast, otos scatter sticky eggs in the aquarium, most often on plant leaves or aquarium glass panes. Spawning is stimulated by a large change of cool water. They may also be encouraged to spawn by the presence of similar species, e.g. cuirass. Hatching takes about three days.

The fry are very small and feed on the tiniest of food, such as rotifers, micro or algae-containing foods.
