Rasbor Brigitte (Boraras brigittae) Vogt, 1978
All Boraras are very beautiful and each species is individually interesting in its own way. This feature makes the fish an excellent object, both for the species, and for a small common aquarium. Fish are also great for nano aquariums.
You can keep this fish with other peaceful fish of the same size, as well as in shrimps. You will not succeed if you keep Boraras with large or aggressive fish, fish will spend all the time in the thickets of plants or other shelters available – because no one wants to be eaten.
Boraras Brigitte – Boraras brigittae.
Synonym: Rasbora brigittae.
Natural habitats: Indonesia, Borneo.
The smallest known until now representatives of carp. On her body, there is a clearly traced green-black stripe just below the sideline, around which bright red or orange stripes pass. The line ends with a black sphenoid dot at the beginning of the caudal fin.
In males, the red color can be all over the body, its brightness will only increase with age. In general, the males are brighter, redder, more contrast than the females, which in their color have predominantly pinkish and orange colors. The dominant male directly blazes with red fire all over his body, but only after reaching the age of 1 year.
Males of the same rank below are not so picturesque.
Size: length up to 2.5 cm.
It is better to keep them in a small group in a small aquarium with dark ground, although the flock of these dwarf rasbor due to its bright color will not be lost even in a relatively large aquarium.
The aquarium should have a lot of small-leaved and floating on the surface of the water plants, among which they like to swim. It is good if you can organize bright and dimly lit areas in the aquarium.
Small carp developed a bright signal color in order to compete with each other in brightly lit areas, and in case of danger they hide in the shade.
Filtration should not be particularly strong, as these fish mainly come from slow flowing waters. If you also use a beautiful, dimmed lighting, you get an almost natural biotope in which the fish live in nature. You can add some Asian plants that can successfully grow in such conditions, such as Microsorum pteropus, Taxiphyllum barbieri or Cryptocorynes.
Use for decoration of the aquarium different types of mosses. A few beams of floating vegetation will be very useful and will scatter the light that enters the aquarium.
Do not run fish in biologically immature aquariums, as they are sensitive to fluctuations in the chemical composition of water.
The water is soft, with the addition of a decoction of peat or preparations of black water. Temperature in the range of 23 – 26 ° C.
The addition of dry leaves (oak or Ketapang almonds) can further emphasize the similarity with the natural biotope and provide additional shelter for fish. Leaves can be left in the aquarium until completely dissolved or changed every few weeks.
Change the water should be about 30-50% of the volume once every 7-10 days.
In nature, they eat small insects, worms, zooplankton. In the aquarium, the daily diet – a small live and frozen food (daphnia, Cyclops, Artemia), along with flakes and granules of good quality, will lead to increased color, stimulates the fish to breed.
Perfect neighbors for all Boraras will be shrimp. Brigitte live very friendly with shrimps (Red Cherry, Crystal Red, Crystal Black, etc.) and complement the composition well – Nano-World.
Rasbor brigitta can be contained with many other nano-fish and larger – Kharatsinovye. One of the large fish that can be safely contained along with micro-assemblies are herbivorous kolchuzhny catfish such as otsinklyus or antsistrusov.
Rasbor Brigitte (Boraras brigittae) the fish is quite nimble and you can watch it for hours, a fish with character and unique behavior.
Adult fish in an aquarium are kept in its upper part, while the only male dominant controls about a quarter of the entire territory. With an aggression that is not typical of this size of fish, the male stands firmly on protecting its domain from the encroachment of other fish.
His courtship with females and “battles” with males look like this: standing up to another fish, head to head or to the tail with head, he begins to “whip” with fins and body towards the opponent, his coloring becomes more intense at that time. In this “fight”, the fish do not cause any physical injuries to each other.
It seems that one pressure of the water created by the movements of the body and the demonstration of the coloring is quite enough to keep the other males under control.
Breeding is not particularly difficult and occurs in the general species aquarium for maintenance. In well-arranged, mature aquariums, a small number of fry may begin to appear without human intervention.
The main condition – the presence of shelters for their larvae, such as Javanese moss and riccia.
The male separates the females he likes from the rest of the group with a kind of dance and gradually leads her to a secluded corner of the aquarium. In the midst of plants, the female spawn, sometimes sitting on top of the plants, and sometimes from the bottom of them, while turning her belly upwards.
Mating ritual occurs almost daily and mostly in the early morning, at the first rays of the sun.
The larvae hatching out are simply incredibly small, to see their very difficult task. For several days they hang on the leaves of plants, feed on the contents of their yolk sac. After 4 days, the larvae are already trying to swim, go up first, and then go down.
And on the next 5th day, many of them assume a horizontal position. From now on, the fry swim almost all the time, but still, most of the time they are in the thickets of plants or near the curtains (if there are any in the aquarium).
At this moment, the babies are almost completely transparent. Now the fry should begin to feed infusoria.
After 5-7 days, nazplia of artemia should be added to the ciliates.
The Firefly (Boraras urophthalmoides), similar to Rasbor brigitte – Rasbora, has a paler, almost transparent body, the pattern on the body in the form of two stripes, one black thickened and golden on top.
Breeding of the species Boraras in a separate aquarium (spawning): Males of all boraras are smaller, narrow-bodied, brighter colored. The color of the females is dominated by a yellowish color, almost no red.
Breeding starts from 6-8 months. Manufacturer’s training consists of fattening them with cyclops and artemia for several weeks.
As a spawning area, use a small aquarium with a length of 20 cm. The water is soft, with the addition of a decoction of alder cones or preparations of black water: pH 5.0-6.5; 1-5 ° dH; temperature 26-28. Filtration is not really necessary, but you can use small sponges with airlift.
You can put a separator mesh. Lighting is dim.
2-3 pairs of spawners are selected for spawning. From the moment the first roe appears, the pairs must be left for several days before they are removed.
It is clear that such tiny fish and the number of caviar is very small. One female Rasbory brigitta (Boraras brigittae) spawns 30-50 eggs. Caviar is transparent, slightly yellowish, small remains on small-leaved plants or synthetic fibers that are not stuck to the bottom.
The embryos develop a little more than a day, and after 5 days the young begin to feed first with living dust, then with nauplii of Artemia. The fry are small, so the problems with feeding in the first stage are very noticeable.
It is not bad to place more javanese moss in a nursery aquarium and add live dust to it. In this case, the fry gather in the thick of moss small food, which is detritus and microorganisms that cannot be found in a hygienic aquarium.
