Hello dear readers of my blog. Today we will get acquainted with the aquarium fish from the Kharacin family and it is called the Diamond Tetra.
In nature, this interesting aquarium fish can be found in Lake Valencia, which is located in Venezuela.
The body of a diamond tetra is high and slightly elongated and is very similar in shape to an oval. The main color of the body of the fish is gray, which, depending on the lighting and habitat, can cast from reddish to yellow shades.
The back can be either gray-blue or brown. The hydrobiont’s belly is painted silver-white.
On the body of the fish you can see small golden, copper and silver specks, which gleam when the light reflects. The fins of the fish are, without exception, gray-black and have a white-milk edge. Males have a brighter coloration and fins are slightly larger than females.
In females, the fins are slightly rounded and smaller. The maximum length of the fish from tail to head is 6 centimeters.
It is best to keep diamond tetras in a flock of 10-12 pieces. The fish keeps mainly the middle layers of the reservoir and sometimes does not hesitate to swim in the shade of aquarium plants. The hydrobiont is quite mobile and bouncy, so be sure to cover the aqua with a cover glass.
During spawning, the males of this harazinki become quite aggressive. A prerequisite is a large number of aquarium plants, in the shadow of which the fish could hide.
But do not forget to leave enough room for free swimming.
Content options should be as follows:
- water temperature in the aquarium: 22-26 degrees;
- acidity: 6.5 – 7.0 pH;
- hardness: from 5 to 10 dH;
- good filtration and aeration;
- regular water changes to fresh.
- Feed the fish can be both vegetable and live food. Sometimes you can vary the diet with their substitutes.
Mature diamond tetras become at the age of 6-8 months. Fish spawn mostly in a separate container, at the bottom of which you need to lay a separator net and plant a couple of aquarium bushes. Javanese moss and Thai fern have proven themselves well.
According to Ilyin’s recommendations, the ideal area of a spawning aquarium should be from 600 to 900 square centimeters, and the water level in the spawning ground should not exceed a 20 centimeter mark.
Unlike water in the general aquarium, spawning should be softer, warm and with an acidic environment. Acidity should be in the range of 6.0 – 6.5 pH, hardness from 4 to 6 dH and water temperature 25-27 degrees. Aeration of the aquarium should not be as intense as during maintenance.
Lighting also should not be strong. Before spawning, females and males should be kept apart from each other for a couple of weeks and strenuously fed.
It is very easy to determine a female ready for spawning – its belly becomes large and enlarged towards the anus.
Producers to spawn are planted in the evening, as they begin to multiply early in the morning. If the female is not ready to spawn, she will hide from the male in the thickets of aquarium plants.
During spawning, the female may lay up to half a thousand small yellowish eggs. At the end of spawning in spawning it is necessary to dim the lighting and set off the producers, and make aeration a little stronger. The incubation period of caviar is 24 hours, and after another 3-5 days the young begin to swim and eat.
You can feed the trifle infusoria or rotifers.
