Aquarium
Keeping tetra fish is a relatively simple task. But in order for them to live as long as possible and delight in their appearance, it is necessary to choose a suitable aquarium for them. For a flock of ten fish, a fifty-liter tank will suffice. A flock of twenty individuals will require a 100-liter aquarium.
It is better to choose a rectangular shape. Of course, in a semicircular tank these small individuals are best viewed, but curved glass otherwise reflects sound waves. They badly affect aquatic inhabitants.
Water
In their natural environment, fish live in the clear waters of the forests of South America. Running tap water will not work for them. It has a high content of chlorine and other harmful impurities.
The temperature in the aquarium should be within + 23 ° ... + 28 ° . Recommended hardness - 15-17 units, acidity - up to 7 units. The flow of water is necessary, but weak.
Fluid replacement is carried out once a week for 30% of the volume of the aquarium.
Priming
Tetra prefer to swim in the green thicket with snags. The water from them is saturated with oxygen. As soil, sand is suitable. From above it can be laid out with stones, snags, tree branches. Plants should be shade-loving, such as ferns.
The light should be dim. In the aquarium you can not do without a filter. If it is external, you will need another aerator. Lots of vegetation needs oxygen at night.
Since the water must be warm, you will need to install a thermostat and a thermometer.
Nutrition
No need to worry about tetra fish food. They eat plant and animal food equally well. The brightness of individuals depends on a varied diet. Bloodworms, cyclops, fruit flies are suitable as live food.
You can give dry or granular feed from a pet store. As a preventative measure of vitamin deficiency, it is recommended to give crushed cooked yolk once a week.
Pets cannot collect food from the ground, so it is better to get a bloodworm. So the water will stay clean longer.
Fish can pluck greens in the tank. So they get the necessary amount of plant food.
Compatibility
Tetra are very peaceful, they get along with any fish. But it is necessary that the neighbors have the same dimensions and character.
The following types can become neighbors:
- scalaria;
- barbs
- swordsmen;
- molliesia.
In addition to the fact that they live in a flock, there should be an equal number of males and females. So there will be no competition for the "lady". However, these fish do not fight among themselves.
Breeding
Getting offspring from tetra aquarium fish is quite realistic. To start spawning, it is necessary to gradually increase the temperature of the water and change its acidity, bringing it closer to seven units. More larvae and crustaceans should be added to food.
Vapors in which the male shows interest in the female are deposited in a separate tank. Vegetation and stones are placed at its bottom. So the offspring will be saved from eating. At one time, the female will sweep one hundred and fifty eggs.
After two or three days, fry will appear, and after four to five days they will begin to swim. Then they can be fed. For the first days, egg yolk is suitable. The original color in young animals will appear in three to four days.
