Striped leporinus is not often found in aquariums lovers of tropical underwater fauna. The fish comes from the Amazon and the waters of Guiana, where the maximum length of its body can reach up to 40 centimeters.
In the conditions of an aquarium, their sizes rarely exceed the 20-centimeter mark.
Leporinus fasciatus possesses a torpedo-shaped bending body of golden color with 10–12 vertical stripes. The fins are transparent with a gray tint. The mouth is equipped with quite powerful lips, with which the fish nibbles perfectly any Vietnamese type algae.
Males have a slimmer body, unlike females. In addition, the males have a stronger colored fatty fin.
Females have a more rounded abdomen and bright orange throat.
The standard body position of fish in the water is head down. Since the hydrobiont inhabits the coastal areas of lakes and rivers that are heavily overgrown with grass and reeds, he spends all the time looking for food at the bottom. In case of danger, the fish immediately takes a horizontal position and merges with the terrain.
Vertical stripes on the body create an imitation of reed stalks, and predators do not notice their prey. If you plan to keep this fish in your aquarium, then you should consider this interesting feature when planning the design of the aquarium.
In order to get good growers in the future, you must keep young leporinus in a large 400-liter aquarium. As the fish matures, they will have to be converted into large tanks (800 – 1000 liter aquariums). In such bodies of water, all sorts of shelters in the form of snags and pipes must be abundantly present.
In addition, the fish requires intensive aeration and high-quality filtration of aquarium water.
The conditions for keeping leporinus are as follows:
- Water hardness 10 – 12 degrees;
- Water temperature 22 – 30 degrees;
- Active reaction medium 6.0 – 7.0 pH.
When the content of leporinus in the home freshwater aquarium, in particular adults, you should take into account that the fish react quite sharply to changes in water temperature even by a couple of degrees and changes in pH parameters. To prevent pets from experiencing stress, water changes are done once or twice a month in small quantities (1/6 – 1/5). In case of sudden changes in the chemical parameters of the water, the fish begin to actively rush around the aquarium and, in the most favorable version, the fish will experience a shock that will pass quickly.
In the worst case, the fish may simply die.
Under natural conditions, leporinus feeds on young aquatic vegetation and small larvae of various insects, worms and other medium-sized living creatures. But, the main emphasis is better to do on plant foods, and you will only dilute the diet with live food. If the fish are kept in soft water, then the percentage of live food in relation to the plant should be increased to 40% of the total.
Excessive enthusiasm for worms, squid meat, shrimp can provoke gonad obesity and fish can remain barren. Regarding vegetable fodder, leporinus is excellently eaten by scalded lettuce, kropiva, dandelion and canned green peas.
For breeding of leporinus striata, it is necessary to select the largest and most healthy individuals. Males should not have any flaws and obesity, body color should be bright. The females, in turn, should be with a round and full belly.
The anal papillae serves as an indicator of spawning readiness.
One male and several females are taken for spawning, which are placed in a volumetric spawning ground (400 – 600 liters) with soft water (3 – 5 degrees), pH 6.2 – 6.4 and water temperature 28 – 30 degrees. Before planting spawners, they must be kept separately in different aquariums for several weeks and actively fed.
Spawning stimuli are pituitary injections, which are used for breeding carp, carp and bream.
Ready-to-breed fish are placed in a spawning tank in the evening. Initially, females will drive the male through the aquarium, but soon the situation will change to the opposite.
To the fish did not experience stress, it is better not to approach the aquarium during mating games. Spawning duration is 4 to 6 hours. This time is enough for the female to sweep away all the eggs.
In order for the fish to have no problems, before replanting the females back to the general aquarium, the remaining eggs of the females should be drained.
At the end of spawning in the aquarium, it is necessary to immediately change the water, because due to the large amount of milt, the water becomes turbid and white. But do not forget about the sensitivity of fish to rapid changes in chemical parameters of water.
Otherwise, a large number of jerky fry will appear among the young.
Externally, leporinus caviar has much in common with chilodus caviar. Initially, the diameter of the egg is 1 millimeter, and after 2 hours it increases to sizes 2.5 – 3 millimeters.
However, in leporin eggs, the shell is not as dense as that of chilodus. The incubation period of eggs at a temperature of 28 – 30 degrees is two days.
In order to avoid mass death of young stock from saprolegniosis or lack of oxygen, aeration should be enhanced in the spawning chamber.
Due to the constant aspiration of the larvae to rise to the surface of the water, they constantly move around the aquarium. After four days, the yolk sac dissolves in the fry, and from that time the young can be fed with the smallest live food.
After a week of self-feeding in the diet of small leporinus it is necessary to add the shredded vegetable food. Leporinus fasciatus is famous for its high fecundity (up to 30 thousand eggs per spawning), therefore, in the case of breeding these fish, you should constantly monitor the quality of water in the aquarium.
The hydrobiont reaches sexual maturity at the age of 2-3 years.
