Hello, friends! Quite a lot of aquarists prefer to keep danios in their aquariums.
I am also an exception, as I kept these fish for a long time. I had three kinds: rerio, pink and leoperdovy.
Today I want to provide you with information on danio breeding.
Before spawning, future producers are seated on opposite sides of the barricades and are fed for a week for slaughter. While you feed them a week in different aquariums, you need to prepare a future spawning breeding ground. If you do not need fry, and you spend spawning only in order that the female was healthy, then a three-liter jar will be suitable as a spawning ground.
Throw a couple of plants to the bottom of the jar and that’s it; nothing more is needed.
But breeding danios in order to obtain offspring requires other activities. To do this, you need to find a container with a volume of 20 liters with a large bottom area.
At the bottom of the aquarium should lay a three-centimeter layer of aquarium soil. Alternatively, you can replace the soil with a fine mesh 4/3 mm, which must be installed a few centimeters from the bottom.
It is very important that the net covers the entire area, otherwise the fish will move under it and eat their future children.
Small things danios are unpretentious inhabitants, it is enough for you to maintain cleanliness in the aquarium, install a sponge filter and carry out aeration of the aquarium. To keep the water temperature constantly buy a small heater.
Plants for spawning fit long-stem, the ideal option is a hornpole and elodey. The presence of plants in the aquarium will stimulate the fish to spawn.
Danio breeding is best carried out at a water temperature of 27 degrees and soft water. Zebrafish can breed at a lower temperature, but as practice has shown, it is better to keep the temperature at 26-28 degrees.
For spawning, scoop water from the general aquarium and dilute it with distilled water. In the spawning aquarium you need to pour no more than 10 centimeters of water.
After the preparatory activities, you need to choose a zebra damsel whose calf is evenly distributed across the abdomen. To breed danios in a common bank is quite problematic due to inappropriate conditions.
Even if the male is active in relation to the female, she does not reciprocate these actions. Perhaps this is the fault of other inhabitants of the aquarium, which cause concern and anxiety in the female zebrafish.
For spawning you need to choose a female and several males (2-3 pieces). Put them all at night in a spawning aquarium and wait for the process. If the conditions in the spawning are suitable, then in the morning the female will begin to spawn.
The spawning process is accompanied by active pursuit by males of the female until they break out of the portion of eggs from it. As soon as the eggs fall out under the plants, the males begin to fertilize them immediately.
This procedure will occur until the female completely loses all of her calf. At the end of this race, the males look calm and fairly tired, while the female loses the roundness of her abdomen.
After spawning is completed, the producers are removed from the spawn. For one litter, the female can produce about 200 eggs, and for them to survive, it is important to add antifungal agents to the aquarium.
Alternatively, you can apply a two percent solution of iodine (3 fell to 10 liters of water) or 25,000 units of penicillin to 10 liters of water. After two days, the eggs should ripen and the larvae will appear on the light, which freeze and attach themselves to everything.
This will happen within 6 days.
As the last 6 days of immobile hovering, the fry are formed from the larvae, which are first fed by infusoria. After a couple of days, you can give lively dust, and after a week add artemia and cyclops to the diet.
If the filtration is satisfactory, you can also give small, dry feed. As young animals mature, soldering should be increased.
Start with the chimney and cyclops, and then gradually lower the water temperature and increase the water level.
