for domestic water fleas Water fleas are animals that can be bred artificially, and it is not particularly difficult to breed them. Although water fleas do not have a particularly high requirement for the surrounding water quality, if the water is not changed for a long time, the dissolved oxygen in the water will be reduced, and the growth and development of water fleas will also be affected, so it is better to change the water regularly. It can be replaced once every 3-5 days, but not all the water can be replaced, because the original water contains a lot of nutrients, all of which will lead to the loss of nutrients. Although the tap water in the family can be used, there are not many nutrients in it, so it is better to replace it with pond or lake water if conditions permit.
quickly? 1. Food: In order to make water fleas explode quickly, ensuring adequate food is the most important aspect. Water fleas mainly feed on plankton, which is not abundant in household tap water, so they can get water from ponds or lakes, which is rich in nutrients. Nutrients in the water can also be increased by adding fertilizer or yeast powder to the water. In addition to yeast powder, there are also some substances that have better effects, such as yogurt, eel powder and so on.
2. Water temperature: In order to make the domestic Daphnia explode quickly, it is necessary to maintain the water temperature within the appropriate range. Specifically, the most suitable range for the growth, development and reproduction of water fleas is 18-25 degrees, and if conditions permit, the temperature can be adjusted to more than 20 degrees.
3. Light: In addition, special attention should be paid to light. In the case of sufficient light, the growth and reproduction of water fleas will be faster. During the day, the container with water fleas can be placed in the sun, and at night, a light source can be prepared to illuminate the water fleas, such as a night light, which can promote the development and reproduction of water fleas.
4. Change water: Although water fleas do not have a particularly high demand for water quality, they cannot always change water. After changing the water, you can also put some duckweed in the water. In addition, it should be noted that there may be oil film in the water during the cultivation of water fleas, which needs to be cleaned up in time.
