General information

Otocinclus is a small fish of the genus Otoncincius, which is a member of the Loricariidae family (chain catfish), with an average body length of no more than 3 cm, though this can vary depending on the variety.

The otika, a lovingly diminutive form of otocinclus, has an elongated, flexible body that is slightly flattened in the abdomen.

The catfish’s skin is heavily coated in tiny bone plates that act as a sort of chainmail to shield it from its natural predators.

The otic’s mouth apparatus is a suction cup; this transformation enables the fish to remain in the reservoir’s currents at a specific location while meticulously scraping algae from the chosen surface.

Usually silvery with a yellowish tint, diluted with small brown spots, Otocinclus vulgaris occasionally has a broad, dark stripe running along its body.

The catfish can breathe atmospheric oxygen because it has intestinal respiration. Thus, you should examine the aerator’s performance if it has become apparent that the otik frequently floats to the top.

Algae form the foundation of the otocinclus diet. When they first start, a group of twenty catfish can readily consume diatom algae in a 100-liter container. The biosphere will then only require the maintenance of two or three people.

Fascinating! For his ponds, master aquascaper Takashi Amano always uses otoncyclus.

Habitat

The Amazon River basin is home to otocinclus in its natural habitat. The catfish favors rivers with swift currents and oxygen-rich freshwater.

Large (up to 1000 individuals) schools of Otoncyclus can be found in sandy shallow waters among snags, large stones, and grassy thickets, eagerly devouring the simplest algae.

Behavior

The fish is calm and serene, but it gets scared easily, which can cause it to change its behavior.

The otocinclus should have become nocturnal as a sign of stress for the catfish if it did.

The aquarium orderly needs company in order to stay calm. Otik should ideally be kept in small groups of four to six people.

The reservoir needs to have isolated areas (caverns, ships, snags, and buildings) where catfish can hide from predators.

Lifespan of a catfish

Otocinclus has a three to five-year lifespan when given the right care.

Because of its gentle nature and small size, otocinclus is a popular and effective algae-eating fish among aquarium enthusiasts. This little fish, which thrives in community settings and contributes to a balanced aquatic environment, is well-known for its capacity to keep tanks clean by feeding on algae. When it comes to maintaining a healthy and aesthetically pleasing aquarium, Otocinclus is a great option for both novice and expert aquarium keepers due to its calm temperament and low-maintenance requirements.

Types of otocinclus

Catfish come in about thirty different varieties. The only significant differences between the varieties are in the color of the otocinclus and the slight variations in body sizes.

In aquariums, the following members of the genus are most frequently found:

Otocinclus affinis

Its diminutive size (up to 5 cm) and unremarkable white and gold coloring set it apart. The back is lined with a broad, dark stripe that ends in a circular area.

Otocinclus negros

Resides in the same-named river in Paraguay. The catfish is only a little over 3 cm in size. The otocinclus can perfectly blend in with the shadows of plants and snags thanks to its color variation, which ranges from gray to brown.

Otocinclus broadband

An adult’s size ranges from 3 to 4 cm. It has a silvery-white belly and is either gray-green or gray-brown in color. The otocinclus got its name from a broad, dark stripe that runs the length of its body.

Quarantine before settling

Newly acquired fish need to be quarantined before they can be housed in an aquarium. This is done in order to treat a small volume of a quarantine reservoir as soon as possible and to detect the disease in time in the event that new people become infected.

A small container with 30 to 40 liters is typically used for quarantine. While adding soil is not necessary, setting up a shelter is worthwhile.

The aquarium has a weak solution of methylene blue, a small amount of peat, and an aeration system in addition to routine water changes.

Take note! Otocinclus does not tolerate the use of copper-based or salt-based products, nor can you dissolve insecticides in water.

Care, maintenance and breeding

Otocinclus is regarded as an unassuming fish, making it appropriate for even novice aquarium keepers.

Aquarium: requirements

The otik fish does not need a large reservoir because it is a small fish. Select a 50-liter aquarium with a wide bottom and straight walls.

It’s important to add decorations or snags at the bottom to create a haven for catfish.

Water parameters

The ideal water temperature to keep otocinclus is between 22 and 23 °C. The ideal ranges for hardness and acidity are 2–18 dGh and 7–7.5 pH, respectively.

Fresh, well-aerated water with minimal nitrate and nitrogen compound content is ideal.

Weekly water changes of up to 30% of the volume are performed to maintain optimal water quality; the aquarium is outfitted with a top-notch aeration system and a strong filter.

Experienced aquarists advise covering the filter tube with a grid to keep small catfish from getting sucked into it.

Plants

The delicate Otocinclus fish can remove algae from even the most delicate plants without causing harm to them. As a result, you can put any kind of algae in an aquarium with catfish.

Soil

A medium or small fraction of the soil should have rounded stone shapes in it. Fish injuries can increase as a result of sharp edges and chips.

Take note! First, the soil needs to be thoroughly cleaned under running water before being added to the reservoir.

Lighting

In aquariums with otocinclus inhabitants, there are always enough plants and quiet areas, so you should select a lighting fixture according to the requirements of the reservoir’s flora.

Feeding

Plant food makes up the majority of an otocinclus catfish’s diet. Although they could theoretically meet their needs by eating the simplest algae, a diet like that would not improve the quality of life for fish. To add variety to the otics menu, use:

• spirulina;
• zucchini;
• lettuce leaves;
• spinach;
• green peas;
• special flakes for catfish.

Brine shrimp, daphnia, or gammarus are a few ways to incorporate a tiny bit of protein into your diet.

How to distinguish a male from a female

In otocinclus, sexual dimorphism is only marginally expressed. A female can only be identified by her slightly larger body proportions and somewhat more rounded belly outline.

Spawning

Otocinclus typically reach sexual maturity at 7 months of age. Before having children, farmers should try to add as much variety and protein-rich foods to their menu as they can.

Take note! Although spawning frequently happens without the aquarist’s knowledge, a pair of otocinclus should ideally be kept in a spawning tank.

Incubator

30 to 60 liters is the ideal size for a spawning tank. Make sure the incubator has a good aerator installed and that the water is fresh, clean, and oxygenated.

Catfish lay their eggs on snags or leaves of algae, so there should be enough plants and ornamental items in the spawning tank. 23 °C is the ideal water temperature.

The producers ought to be put back into the main reservoir after they have spawned. To stop the growth of fungus, a weak solution of methylene blue is added and the incubator’s water temperature is gradually raised to 26 °C.

Growing fry

By the end of the first week, the fry hatch from the eggs in such circumstances. You should stop adding the blueing solution once the fish hatch.

The fry’s diet is supplemented with mashed egg yolk, infusoria, or microworms on days three and four. Remember that algae is the main component of the otocinclus diet.

Compatibility

Any peaceful fish that does not engage in aggressive behavior toward them gets along well with catfish.

• Sack-gill catfish: a predator with poisonous spines
• 3 popular varieties of Tarakatum catfish
• Ampularia: harm or benefit for the aquarium?

If you want to add a small, hardworking algae eater to your aquarium, the Otocinclus, also known as the "Oto," is a great option. These little fish add a lively activity to your aquatic setup in addition to being effective at controlling algae. They get along well with a wide range of other species in most community tanks because of their gentle nature.

Otocinclus maintenance is quite simple, but keeping the environment in the tank clean and in balance is crucial. Maintaining your Oto’s health and well-being can be achieved through routine water changes and appropriate tank care. They’ll stay content and well-fed if you feed them a varied diet that includes fresh veggies and algae wafers.

To sum up, the Otocinclus is a diminutive yet powerful fish that has both utilitarian uses and aesthetic appeal. Their ability to consume algae and their calm nature make them an invaluable addition to any aquarium. They will maintain the excellent appearance of your tank and help maintain a healthy aquatic ecosystem with the correct maintenance.
