Barbus Denisoni: content, description, photo, video, reproduction
Denison Barbus (Puntius denisonii) - a beautifully colored, relatively large and very mobile aquarium fish. Ideal for keeping in large, over 400 liters of aquariums. Fish are not aggressive, indifferent to ornamental plants, have excellent health and are not whimsical in nutrition.
Homeland barbadon denison - fresh water bodies of tropical India. And more precisely, these are several rivers flowing in the southwestern part of the country, along the territory of the states of Kerala and Karnataka.
These places are a real biological treasury, included in the world's top ten areas of species diversity, there are about 300 species of fish alone, a significant part of which is an object of ornamental fish farming.
Fish habitat barbad denisoni mountain rivers and streams saturated with oxygen are considered, characterized by a fast current and concentrated in the western part of India and in Asia. These fish were described in various sources long before their official appearance in Europe. It is believed that they were brought into Europe in 1997. These amazing fish have exotic colors, unusual behavior and will become unique inhabitants of the aquarium.
Sexual characteristics and external characteristics
Barbus denisoni possesses a lanceolate body of golden silver color, and a black line stretches through the body. On this strip there is a bright red line and stretches to the dorsal fin. It, in turn, is distinguished by an olive color, and on the tail there is a V-shaped neckline with transverse lines of black and yellow. The front rays on the dorsal fin are distinguished by a red tint, while other fins are transparent. In a comfortable fish habitat, barbs grow up to 15 cm and live up to eight years. Barbus Denisoni prefers flocks. Males practically do not differ from females. In females, the abdomen is somewhat more round, which is most noticeable when they are bearing offspring.
LIVING IN NATURE
Denisoni's barbus was first described in 1865, and he hails from South India (Kerala and Karnatka). They live in large schools in streams, rivers, ponds, choosing places with a large number of plants and a rocky bottom. Habitat water is usually rich in oxygen.
Like many other fish, the Denisoni barbus has changed its scientific name several times during its discovery, now it is called: Puntius denisonii. And earlier he was: Barbus denisonii, Barbus denisoni, Crossocheilus denisonii, and Labeo denisonii. And at home, in India, his name is: Miss Kerala.
Unfortunately, this barbus can be given as an example of a situation where a great interest in the market suddenly arises for fish. After he was recognized as one of the best fish at the international aquarium exhibition, demand for him has risen sharply.
Within a decade, more than half of the Denisoni barbus population was exported from India. As a result, the overall decline in the number of fish in nature, due to almost industrial fishing. Industrial water pollution and the settlement of fish habitats also played a role. The Government of India has taken measures to ban the catch of barbs in certain periods, they also began to breed it on farms in Southeast Asia and Europe, but it is still listed in the Red Book as a fish that is threatened.
Aquarium. The size of Miss Kerala individuals is rather small, and they live only in a pack, therefore the volume of the aquarium should be large. For example, a group of 7-12 copies is recommended to be kept in a 200-liter “jar”, and it is desirable that it be a rectangular long shape.
The presence of space for rapid movement - this is what is needed for a flock of "red comets" who prefer to be in the middle and lower layers of the water mass.
Vegetation. For the same reason, plants are planted along the edges of the aquarium landscape; they must have strong roots in order to successfully resist attempts to dig up the soil. Vallisneria, hornwort, cryptocoryne, echinodorus have proved to be quite good.
Bottom organization. Fine pebbles or coarse river sand of natural origin are ideal for soil. An artificial substrate is also suitable, but it should be ensured that it is neutral in terms of chemical composition. Also, snags, small grottoes and caves where fish can hide can be set along the edges.
Water parameters. There is an opinion that Puntius Denisoni requires some special treatment, and the level of its content is considered difficult. Based on the required water parameters, there is nothing complicated:
- temperature range - from + 20 ° C to + 25 ° C,
- pH balance - close to neutral (6.5–7.5 units),
- rigidity - from 8 to 13 degrees.
Equipment. To create conditions similar to natural, aeration should be intense, and the filter with a powerful pump for the most effective cleaning and creating a flow of water. Fish do not tolerate an excess of nitrates and nitrites at all, therefore, in addition to biological treatment of the aquatic environment, weekly changes are necessary: 30% of the total volume.
It must be emphasized that the practice of keeping up is still very poorly developed, and there is an explanation for this: insufficient prevalence of the species in the domestic aquarium.
In general, the Denisoni barbus is a peaceful fish, but can be aggressive to small fish, and should be kept equal or large in size with the fish. As a rule, reports of aggressive behavior relate to situations where they contain one or two fish in the aquarium. Since Denisoni is quite expensive fish, they usually buy a couple. But! It needs to be kept in a pack, from 6-7 individuals and more. It is in the pack that the aggressiveness and stress of fish is reduced. Given that it is rather rather big, an aquarium is needed for such a flock of 55 liters. Good neighbors for Denisoni will be: Sumatran barbus, Congo, diamond tetra, thorns, or various catfish - cockroaches, corridors.
There are no obvious differences between male and female. However, sexually mature females are somewhat larger, with a fuller belly, and sometimes less brightly colored than the male.
It is produced in special nurseries. According to some reports, it is stimulated by hormonal injections. That is why home amateur breeding is unlikely to succeed.
At the same time, in a number of sources you can get acquainted with at least two cases of aquarium breeding.
- The first was in Germany, when spawning occurred in a flock of 15 individuals by gradually lowering acidity. Hundreds of tiny eggs were laid on thickets of Javanese moss.
- The second known case was observed in the aquarium of an English zoo. Employees of the institution consider this case of spawning an accident.
A beautiful, bright, fast and peaceful decorative fish, the Denisoni barbus is still not so common in domestic aquariums. One can only hope that over time the “red torpedo” will take the place that it undoubtedly deserves.
Sahyadria denisonii is an omnivorous species of cyprinids. In captivity, they are happy to use daphnia and brine shrimp, bloodworms and coronet, and as a plant food you can give finely chopped zucchini and cucumbers, spinach and lettuce.
By the way, there is another way of feeding salad: the leaves are washed well, then scalded, lowered to the bottom of the aquarium, pressing the edge with a pebble. Decorative carps are happy to bite off the edges of the leaf.
Branded balanced feed for medium and small cyprinids, which are produced by Tetra, Sera, JBL and others, are also suitable.
