In the fight against algae, catfish have proven themselves well. In species of fish ottsinklyusy content is very simple, they are peaceful and unpretentious.
No special conditions are required. Ototsinklyus is often called simply from.
Somics eat brown, green and red algae, including black beard. Ototsinklyu belong to the family kolchuzhnyh (lorikarievyh) catfish. Popular along with the Siamese algae.
The area extends to Venezuela, Brazil and Argentina. Otocinclus affinis are kept in flocks in which the number of individuals can reach several hundred.
The chainmail of this catfish was called due to the presence of protective bone plates. The body is elongated, slightly flattened at the sides. Reaches 3–5,5 cm in length.
The back is dark, the plates are yellow-gray, and the belly is white. On the sides are longitudinal dark stripes.
Dorsal and pectoral fins sharp, transparent. Mouth with suction cup, eyes large.
Species in color are different.
By nature, catfish are peaceful and shy. The most active in the evening, but you can catch them for cleaning glasses and stones at any time.
Hardworking, quickly clean the aquarium from algae.
With good care, otsinklyus lives 5-6 years.
There are more than 17 varieties of otzinclus, which are sold under the common name. All species are suitable for keeping in an aquarium. The most common types are:
Otozinclus requires clean, fast-flowing water saturated with oxygen. The optimal content of fish in groups of 6 individuals.
Somiki, bred in nature, require a long adaptation to the aquarium, they are more fastidious to food.
Before running into the aquarium, place the newly acquired fish in a quarantine tank. As a quarantine, use a 30-liter aquarium without soil. If the disease is not detected within 3–4 weeks, settle the otozinclus into a common aquarium.
For quarantine suitable water with a small content of peat. Add methylene blue solution for prophylaxis.
Do not add salt, solutions containing copper and insecticides to water, as the otozinclus does not tolerate these substances.

For the maintenance of a group of 6 individuals, an aquarium of 70 liters is enough. Pick up a tank with a wide rectangular bottom. Place a few shelters and kryag.
|Water temperature||21–27 degrees|
High quality water with a low content of nitrates (up to 10 mg per 1 liter of water), without nitrites is required. Weekly, change up to 30% of the water in the aquarium to fresh.
Plants serve as shelters. For a comfortable maintenance of catfish ototsinkly landed a large number of plants:
Pick up the soil without sharp corners, small and medium fractions. When dye content in soil particles, make sure that the materials are non-toxic to fish.
For the maintenance of catfish, pick up a powerful filter that lets water through in the amount of 3-5 volumes of the aquarium per hour. If the filter has a suction tube, protect the fish by blocking the tube with a grill or net.
Quality aeration is also required.
When arranging the lighting system, rely on the needs of plants.
The basis of the diet of otsinklyusov – vegetable feed:
Boil vegetables for 1–2 minutes. before serving. Attach food to the snag or stone.
Remove leftover food no later than in a day. Somica otozincluses quickly eat algae.
So that they have enough food, take the stones and a couple of sprigs of plants from the aquarium and put them in the sunlight. Algae will appear in 2 weeks. Add to the diet of protein feed:
Ototsinklyus compatible with peaceful fish:
Do not lodge catfish in a tank with algae and antsistrusami. When the content of different species that eat algae, there will be competition. Bad neighbors are also aggressive species:
Dilution of otsinklyus occurs in the general aquarium or spawning. Sometimes reproduction takes place without the knowledge of the aquarist.
The male has a slender belly. Females are more rounded and large.
Sexual maturity begins at the age of 7 months. Before breeding, feed otsinklyus with mammarus, bloodworm, or pipe worker, but do not forget about the content of algae in the aquarium.
Manufacturers lay eggs several times a year. When kept in a group, the fish are broken up into pairs, previously arranging clashes between males.
Future parents are clearing spawning grounds.
To save offspring arrange spawning. Comfortable conditions and water parameters:
|Plants||mosses, anubias, cryptocorni in large quantities|
Place the producers in spawning. Spawning occurs in the morning. Fishes lay eggs among plants or stick them on the underside of leaves.
During one spawning, oocytes are producing 60–130 eggs. After spawning, seed the fish and gradually raise the temperature to 26–28 degrees.
Add a weak solution of methylene blue to the water to protect the eggs from the effects of fungal infections.
Fry hatch in 3-7 days. Adding antifungal solution at this stage can be stopped. After 2-3 days, start feeding the fry:
Change up to 30% of water 1-2 times a week. When changing the water, put a thin mesh over the siphon or hose so that it does not suck in the fry.
When keeping the fry, the height of the water should be at least 5 cm. After a couple of weeks, the young individuals are painted and become similar to adult otzinklyusov.
Somik are susceptible to poisoning in polluted water. Keep track of the level of harmful compounds and do not neglect water changes. If the fish stay near the surface of the water and often breathe, this indicates hypoxia – a lack of oxygen that occurs during overpopulation, insufficient aeration and pollution.
Possible appearance of parasitic and diseases, such as gill trematodes or ichthyophthyriosis (semolina). Diseases are treated with special drugs.
All decorations and plants must be disinfected in a solution of potassium permanganate.
Opinions of aquarists are divided: some are delighted with the otozincluses, others have difficulty feeding and keeping fish. The low appearance of the otozinclus is also a minus for some.
Ototsinklyus can be bought for 170–300 rubles. Price depends on the size of the fish.
The content of algae fish greatly reduces the amount of algae. But remember that fish are not always effective.
If there is an outbreak of algae in the tank, this indicates a failure in the aquarium biosystem. Eliminate the cause of the occurrence of lower vegetation, because an unidentified biobalance is dangerous for all the inhabitants of the reservoir.
