Tape (striped) leporin (Leporinus fasciatus) belongs to the family Anostomovye (Anostomidae) (uzkorotye).
The birthplace of these fish is South America – the Amazon and Orinoco rivers basin. A favorite place near the coast and islands of vegetation.
There is an interesting feature – the number of bands on the body depends on the age of the fish, like the annual rings of trees. Young fish have only 5 lanes, by the first year of life the first is divided into two more, and by the age of 3 years there are already 9 black stripes.
Requirements and conditions:
- The volume of the aquarium – from 200 liters. Temperature – 22-28 ° C pH value – 5.5 – 7.5 Water hardness – from very soft to hard (2-20dH) Substrate type – sandy Lighting – moderate Brackish water – no Water movement – strong
- Size – up to 20 cm. Food – vegetable. Life expectancy – from 7 to 10 years.
Fish was discovered in the late 18th century by the river systems of Central and South America, also widely distributed in the Amazon. They live in fast moving rivers. During the rainy season, they move to the flooded areas of forests.
When the water recedes, fish often remain in ponds and creeks. They feed mainly on algae, plant debris, worms, insects, and sometimes small fish.
In nature, it is a large fish, reaching a length of 30 cm, less in an aquarium – 15-18 cm, rarely grow to 20 cm in length. Body color Tape (striped) leporin silvery yellow.
9-11 dark brown stripes run along the whole body to the caudal fin. Fins are large, well developed – transparent, often with a grayish tinge. The female is fuller than the male.
In color it differs from it in an orange throat. Red snout and eyes stand out against the general background of the body of the fish.
At night, the body color changes to brown with subtle cream marks. When frightened, or, conversely, during undisturbed sleep, a brown lattice appears on the body of the fish.
As for the content in the aquarium, striped leporinus very unpretentious to the conditions of detention. Despite this today they are not often found in aquariums lovers.
In connection with a sufficiently large, for aquarium fish, size and schooling way of life, an aquarium of at least 300 liters is necessary for their maintenance. In such a spacious tank, with effective filtration and aeration, fish care is not difficult.
Water filtration should be powerful enough; an external filter with a capacity of at least 5 volumes per hour is best suited for this. This will help maintain the necessary biorezhim in the aquarium, which, in turn, will save the fish from possible diseases.
In optimal conditions of detention leporinus sick quite rarely.
For greater similarity of the interior of the aquarium with its natural habitat, it is recommended to use coarse-grained river sand with fallen leaves, driftwood and branches as soil.
Can be placed in the aquarium and live aquatic plants, but it is likely that one day they will be eaten leporinus.
But with proper feeding striped leporinus almost do not spoil the plants, especially if the aquarium is brightly lit and it has enough algal fouling.
In such a tank leporinus constantly “graze” keeping in the water column upside down.
Water quality is extremely important. Do not place fish in an aquarium where biological balance has not been established.
The aquarium should always be closed from above with a lid or cover glass, as representatives of all kinds leporinus often jump out of the water.
In a large container you can keep a group of fish of 6 or more individuals. Flock leporinuslooks spectacular in a large demonstration aquarium.
The group quickly establishes hierarchical relationships.
Leporinus get along well with most non-aggressive species of fish of medium and large sizes such as: haracinids, loricaria, dorades, including aggressive cichlids of the great lakes of Africa.
Smaller species can be prey to larger ones. leporinus, and slow-moving large fish risk being left without fins.
The optimal parameters of the aquatic environment for keeping fish are as follows: temperature range from 20 to 28 ° C, pH from 5.0 to 7.5, hardness up to 12dGH
Regular water changes have a positive effect on growth rate. striped leporinus.
Fish prefer vegetable food. You can serve as a specialized industrial feed from vegetable raw materials (vegetable flakes, dried algae plates, various granules, etc.), as well as homemade preparations of finely chopped leaves of spinach, lettuce or young shoots of tender plants.
With a lack of food can suffer aquarium plants.
Leporinus striped is quite peaceful if it is contained in a group of at least 6 individuals of any species, with a smaller number showing signs of aggression. This species is compatible with other fish of similar size and temperament, and is dangerous for small fish.
The negative trait of the Leporinus behavior is the “love” of the long fins, which they often chew.
At home, there are no successful breeding experiences, since it is not possible to reproduce the conditions of the rainy season and the possibility of migration. Leporinus are caring parents; in nature, the male makes a kind of nest where the female lays eggs, and then protects her until the appearance of offspring.
This fish is also known as “Leporinus tape”, “Leporinus striped zebra”, “Leporinus zebra”. Fish are often sold without providing buyers with information about the potential size of adults and the requirements for care.
They can be found in almost all aquariums installed in public places. This genus includes many species that are externally similar to Leporinus, therefore, it is often confused with other fish, such as Affinis.
According to the results of the study by Makhnert (1997), Leporinus differs from Affinis by the following features: it has 6-7½ rows of scales between the lateral strip and dorsal fin (Affinis has 8-9 rows); 5-6 rows between the lateral stripe and the ventral fin (Athenis, 6-8 rows); along the lateral line at Leporinus there are 40–45 scales (at Affinis, 40–45 scales); from 8 (in young individuals) to 10 (in adults) wide and slightly inclined stripes (in Affinis – 8 perpendicular stripes). Also, the authors of the study claim that the anal fin at Affinis has a rounded and oblong shape. Also, it should be noted that Gunter (1864) counted 11 dark stripes near Leporinus.
With age, the number of strips increases. Young individuals have no more than 5 stripes.
New stripes appear as a result of separation every 6 months until the individual reaches puberty and the pattern is completely formed. Leporinus is one of the most diverse groups of characteristic species, numbering about 90 species.
During the phylogenetic study, the scientists Silauskas and Vari established that this group represents a single polyphyletic branch. Four species (H. despaxi, H. megalepis, H. mormyrops and H. pachycheilus) were assigned to the re-studied genus Hypomasticus, originally designated by Borodin (1929). The remaining Leporinus species, with the exception of L. Gomesi, were combined into a group along with the Abramites, which was included in the large polytomic system along with Anostomoides, Anostomus, Gnathodolus, Laemolyta, Petulanos, Pseudanos, Rhytiodus, Sartor, Schizodon and Synaptolaemus.
In particular, for the period of the study there was a lack of data on genetic relationships in the species Leporinus, and the authors suggested that a molecular study would be required to fully study these relationships. Representatives of the anostomid family inhabit a large area of the tropical and subtropical regions of South America, from northwestern Colombia to central Argentina. Most of the species have a slightly elongated and slightly rounded body, although there are exceptions, for example, relatively tall abramites.
Even more diversity manifests itself in the anatomy of the oral cavity. Representatives of the family demonstrate a large number of adaptations in terms of the structure of the teeth and jaws.
Some anostomid swim not horizontally, but at an angle, “upside down.”
