The native land of the Synodontis-shifter (Synodontis nigriventris) is Africa, a river basin of Congo. Rather interesting small fish, its basic feature is that it constantly floats up a belly, as dead fish (except for gathering of a forage at a bottom). The reasons of such behaviour are not known till now. To Europe the Synodontis nigriventris has been delivered for the first time in 1950.
The Synodontis nigriventris possesses thickset, slightly flattened on each side a body covered with a mucous and strong skin. A back profile will curve more strongly, than a belly. A mouth bottom with three steams of moustaches. Eyes big. A back fin of the triangular form with a powerful first beam. A tail fin two-bladed. There is a large fatty fin. The basic colouring of a trunk serovato-beige with scattered on all body and fins black-brown stains. The paunch Synodontis nigriventris is more dark than a back. Sexual differences: the male more small and more harmonously a female; the trunk of a female is covered by larger stains. At length the female grows to 9,5 sm, males to 6 see Life expectancy in an aquarium till 10 years.
The Synodontis-shifter (Synodontis nigriventris) a peaceful and gregarious small fish. Activity starts to show with approach of twilight, and hides in various shelters in the afternoon.
To contain the Synodontis nigriventris it is possible in an aquarium in volume from 50 litres with plants, including floating and various shelters: snags, grottoes, hollow tubes, flowerpots without a bottom. As a ground use run-in sand or gravel that fishes have not damaged short moustaches.
Parametres of water for the maintenance of the Synodontis nigriventris: rigidity 4-15 °, рН 6,5-7,5, temperature 24-26 °С. The filtration, aeration, weekly substitution to 30 % of volume of water is necessary. Synodontis-shifter it is very difficult to catch in a net, and it is even more difficult to shake out it whole and safe, as it spreads the fins supplied with prickles. We will combine the Synodontis nigriventri with small fishes of the same size and temperament (smaller and sluggish fishes do not approach it).
The Synodontis nigriventri uses the live, vegetative and combined forages. It is inclined to an overeating, therefore it is desirable to arrange 1-2 times a week days of limited intake of food. Under adverse conditions of the maintenance the metabolism that can lead to a dystrophy or fat adjournment is broken.

The aquarium in volume is necessary for spawning of the Synodontis nigriventri from 50 litres with various shelters and floating plants. Parametres of water for cultivation: rigidity nearby 10 °, рН nearby 7,0, temperature 24-27 °С. Natural spawning in the conditions of an aquarium occurs seldom, therefore to cultivation apply a hormonal injection. Before spawning of manufacturers (1 female and 1 male) is necessary for seating for 1-2 weeks and well to feed (vegetative food should make not less than 30 %). During spawning the male actively pursues a female (small fishes are in position - up a paunch), then nestles on it and they for an instant fade, and in water there is a small amount of not sticky caviar of yellow colour, diameter about 1-2 mm. The female of the Synodontis nigriventri throws to 1000 berries which then are freely carried away by a water low flow. After spawning of manufacturers delete, a current weaken. The incubatory period lasts about 168-172 hours. Fry small and from first days of life at them negative reaction to light, therefore an aquarium is shown it is necessary to black out. To float and eat they begin for 4-8 days. A starting forage: a live dust. The first days of the life fry the Synodontis nigriventri float as all fishes, a belly downwards, but at achievement of 7-10 weeks, turn over a back downwards. Grow slowly.
Sexual maturity the Synodontis nigriventri reaches at the age of 2-3 years.
