How to raise the Luohan seedlings of 2cm

In daily life, some people like to raise fish in their spare time, but fish farmers should know that raising seedlings is a risk and a challenge. So, how to raise the Luohan seedlings of 2cm?

How to raise the Luohan seedlings of 2cm

Be sure to ensure the impact of the current and change the water every 3 days. During the fry period, you can feed some red insects by feeding at least 2 meals a day. In order to ensure the healthy development of the digestive system, it is recommended to turn off the lights for Luohan seedlings to rest after 1-2 hours of feeding.

1. Bottom sand

When raising flower Luohan, most people raise it in a bare tank. It may be that Hua Luohan has the nature of a large American sea bream who likes to turn the sand, especially in estrus. The sand and gravel in the tank is often turned beyond recognition, and the dirt in the bottom sand will be raised, so it is raised in a bare tank. However, properly covered with a layer of sand and gravel, not only contribute to the stability of the water quality, but also contribute to the color of the flower, especially with red and other colorful sand and gravel. However, no matter what kind of color the sand and gravel is laid, the most important thing is not to affect the pH of the water quality, because some sand and gravel will release substances that make the water quality acid or alkali, which will affect the growth of the flower Luohan, so it is best to avoid using it.

2. Water quality

The quality of water quality for many fish species, as long as a little deviation can lead to a fatal crisis. But for fish like Hua Luohan, because of their strong adaptability, most people have long ignored the importance of water quality. In both Singapore and Malaysia, the author saw that no matter professional farmers or beginners, almost as soon as the faucet was turned on, the new tap water filled the fish tank without aeration, nor did it need to go through the process of adjusting the water temperature and water quality. I immediately introduced Hua Luohan into the fish tank, and what surprised me most was that the fish immediately adapted to the water. However, even if Hua Luohan is really strong, he should not be treated in this way. It is suggested that, like raising other ornamental fish, treat the new water, measure the water quality and water temperature, and then slowly put the fish into the new environment, so that accidents are less likely to occur. Generally, the water quality condition of raising flower Luohan is neutral soft water, and the water temperature is 28 ℃.

3. Filtering

For Hua Luohan, a kind of fish with high food intake and high metabolism, the filtration system must not be careless. It is best to use a highly efficient filtration system with a large amount of filtered water to quickly remove the toxic substances left in the water so as not to cause disease in the fish. Of course, the filtering system has a variety of options, whether it is built-in filtering system or external filtering system. The use of filter materials is even more diversified, from filter cotton, dechlorite, biochemical balls, activated carbon, ceramic rings to sand and gravel, but the author suggests that filter materials should be used in a variety of ways, and pay attention to the aging of filter materials and the amount of water treated at any time, and timely replacement will not lose its effectiveness.

4. Lighting

Moderate lighting has a positive effect on the color of Hua Luohan. It is common to see fish farmed in pond fields, whose color is much brighter than that of individuals raised in captivity. Although sunlight is not the main reason, for fish raised in an artificial environment, if appropriate lighting is not provided, their body color will never be very beautiful. Fortunately, the industry has developed lamps and lanterns suitable for all kinds of fish tanks and shapes, which can be illuminated for an average of about 10 hours a day. Lighting for too long is easy to grow algae in the water, which will not only hinder viewing, but also lead to the improvement of water quality. there may even be a risk of anoxic death of fish.

5. Heating

Fish fans living in the tropics can be said to be lucky in this respect, because the weather is hot and the temperature is stable, so they need to pay less attention to the effect of water temperature on Hua Luohan. However, for fish fans in subtropical areas or at high elevations, the effect of water temperature on Hua Luohan should not be ignored. Because Hua Luohan is easily infected with white spot disease through drastic changes in water temperature, so living in areas where the temperature is not stable above 25 ℃, it is best to install a thermostat in the tank where Hua Luohan is raised, and set the temperature at about 28 ℃ to prevent the water temperature from suddenly falling below 25 ℃ and getting sick. In order to prevent unlimited heating of water temperature, it is also necessary to use temperature control rods with temperature controllers.
