    Spawning aquarium from 60 cm long, without soil. With large-leaved plants, the leaves of which float or are located close to the surface. Spawning sometimes occurs in the general aquarium after changing the water. A group of fish is planted for spawning, usually an equal number of males and females.

    Petitella is a very interesting fish. My son was so fascinated by the observations that the Russian Language Composition on how he spent his holidays was completely devoted to this beautiful fish.


    Originally from South America. It is found in nature in the basin of large tributaries of the Amazon River, such as Purus, Rio Negro and Madeira in Peru and Brazil. Inhabits small streams and rivers flowing under the dense canopy of the rainforest. The bottom is usually covered with a layer of fallen leaves, branches, various snags. The water is dark in color due to the high concentration of tannins resulting from the decomposition of plant organics.

    Maintenance and care, arrangement of the aquarium

    The optimal size of the aquarium for a flock of 6-10 fish starts from 70 liters. In the design, it is recommended to use a dark substrate on which to place several natural snags. Aquatic plants are optional, but several species floating on the surface can be used for shading. The lighting is dim.

    A good choice is the leaves and bark of some trees, which in the process of decomposition will saturate the water with tannins, as happens in nature, and give it a tea shade. More details in the article “Leaves of which trees can be used in an aquarium”.

    Fish need clean water, do not tolerate the accumulation of organic waste (residues of feed, excrement) and need very soft (dKH) acidic water.

    Accepted almost all types of food of suitable size in dry, frozen and live form.

    Behavior and Compatibility

    The false Red-Nosed Tetra is peaceful, prefers to be in the company of relatives, so it is worth buying in flocks of 6 individuals. Compatible with other calm fish of comparable size, for example, apistograms and other small South American cichlids, catfish corridors, tetras, as well as small barbs, parsings and others.

    Breeding / breeding

    Under suitable conditions and a protein-rich diet, the likelihood that the fish will become spawning is very high. With the onset of the breeding season, females either scatter eggs along the bottom, or toss eggs in among small-leaved plants, mosses or ferns, if any.

    Parental instincts are not developed, so there is no concern for future offspring. Fish tend to eat their eggs and fry. If breeding is planned, then spawning is preferably carried out in a separate tank, where males and females are placed in advance. The latter can be distinguished by markedly increased abdomen.

    Fry emerges from eggs within 24–36 hours. After 3-4 days, they begin to swim freely. From this point on, special feeds can be supplied in the form of powder, suspensions, or, if possible, live foods such as Artemia nauplii.

    Fish disease

    The main threat to fish health is poor living conditions. The cause of the disease can also be contact with a new infected fish, injuries, poor nutrition. If the first symptoms are found, first of all, it is necessary to check the environment in which the fish are and if there are problems, correct them. If you maintain or further worsen your well-being, you will need to take medication. More details in the section "Aquarium fish diseases".
