Hello dear aquarists. I think not every one of you contained such an aquarium fish as black ornatus in your aquarium.
Homeland habitat of this harazinki is the basin of the Rio Guaporé. Fish is quite interesting both in behavior and in appearance.
If where you get in your eyes – buy without hesitation. But still let’s take a closer look at this aquarium inhabitant.
The body of black ornatus (black phantom) is slightly flattened laterally, the dorsal fin is rather high, and the caudal fin has two blades. Like all haratsinok, the black phantom has a small fatty fin. The main body color of the fish is gray, sometimes even completely black, and towards the belly it becomes lighter. On the sides of the fish there are spots of unknown shape, and around they are surrounded by purple edging.
In fish, even the fins are all black, except for the pectorals.
The male dorsal fin is slightly curved and high. In the female, this fin is significantly shorter and not as tall as in the male.
The females are painted brownish-red, the red ebb also exists on the fins. If the fish is still young, then red colors predominate in the coloration and the floor is difficult to determine.
At length, black ornatus usually grows to 5 centimeters.
The black phantom is a peace-loving and gregarious aquarium fish. Therefore, as neighbors, I would recommend other characters, for example rhodostomusy, red neons, which are also kept in packs.
To fish in the aquarium looked spectacular, it is desirable to buy about a dozen individuals. As practice has shown, the relations of ornatus with serpas and minors, blue neons and nanostomuses are rather strained. Also a lousy neighbor for black ornatus hemigrammus, which is harsh like diarrhea, which is very problematic for the calm temper of a phantom.
Basically, this type of ornatus prefers to keep in the middle layers of the aquarium in shaded places.
Phantom will be fine to live in an aquarium, the volume of which is 50 liters or more. The only aspect that needs to be given due attention is the large number of shelters created with the help of snags and stones and thick planting.
Do not hesitate to floating plants, such as pista or Guadalupe naiad. To create shaded areas with the help of plants, you can take a red capsule and some kind of cryptocoryne, and in the background plant a shadroot and elodea.
I think you will come up with something worthwhile. But do not forget to leave enough space for your pets to swim.
Aquarium water is preferred old, in which a lot of peat extract. Try not to allow an increase in water hardness above 10 dH, an acidity of 6.5-7, and a temperature to be kept within 23-25 degrees Celsius.
A mandatory attribute of any aquarium is the filtration and aeration of the aquarium + regular weekly changes in the amount of 20% of the total. What I like more in this fish is its resistance to various diseases.
Here are just oodiniosis and ichthyophorosis for them is a problem.
As a rule, the parasites contributing to the development of these sores are introduced with live food, which is extracted from a natural reservoir in which fish live. In addition, a sharp drop in water temperature can provoke the development of invasion. Thank God that the black color of the fish makes it possible to determine its ichthyophorosis at an early stage.
And this, in turn, helps to quickly and effectively cure ailment with the help of tetra drug “Contra Ich”. These two drugs have proven themselves quite well: Odimor and Faunamor.
When you treat black ornatus, raise the water temperature to thirty degrees. The duration of treatment is usually a week, + a couple of days. If you see whitened areas of muscle tissue in other inhabitants, then this is most likely neon disease or plysteophorosis.
These two sores begin to develop usually from the caudal fin. Unfortunately, you will not be able to cure this fish, so the sooner you find infected fish, the better.
Just decide what it is, if the aforementioned crap, better flush the fish into the toilet than infect the whole jar.
Mostly black ornatus likes to eat small live food, in most cases they like cyclops. If you don’t feed him to the younger generation with little, then in a month their color will become pale instead of black.
In addition, the black phantom loves to taste small moth, coret, daphnia and dry combined food.
To breed black phantom, you need a capacity of 10 liters per pair of fish. Place a separator net and a small-leaf plant at the bottom of the spawning bed.
Java moss is the perfect solution. Spawning at the phantom pair. These should be the parameters of water in the spawning pool: hardness – not more than 2 °, pH – not more than 6.5, and temperature 27 degrees.
The water level in spawning should not exceed 15 centimeters.
Set diffused and at the same time dim lighting. Before identifying spawners, the male and female are kept separately and abundantly stuffed with live food, with the exception of the tuber.
Spawning will begin on the third day after landing of future parents in spawning. During the mating season, the males change their color to a brighter one.
The male, like a pompous turkey, spreads its feathers and cakes in front of the female. When they press bodies together, the female throws about a dozen eggs and then the procedure is repeated again. Then spawning activity will decline and the female will produce up to 400 eggs in one spawning.
After that, the exhausted mother swims into the dense thickets of plants and sits there.
In order for the caviar not to die, it is better to add half a tablet to 15 liters of water in the spawning ratio of erythromycin. You will need to crush the pill and the powder in the bag is located opposite the water flow. As soon as spawning is over, the producers are removed from the aquarium, the grid is shaken off, a small aeration is turned on, and the spawning is lightly shaved.
After a couple of hours, you should remove unfertilized white caviar from the jar. The incubation period of caviar is a day and a half, after which fry are born, which after three days can swim and eat on their own.
The initial small food feed is rotifers, cyclops nauplii and ciliates. If there are floating plants in the spawning farm, then natural food will appear in their thickets, which will be additional food for fry ornatus.
Periodically in the spawning pool, change the water, but gradually and often. Somewhere in 40-45 days of life, the young change their color: slightly orange will turn gray and then turn black.
First, the abdominal and anal fins are reddish, and by 5 months they will darken. Black ornatus become sexually mature by about 6-7 months of life.
