How to raise the Luohan seedlings of 2cm

Bottom sand: the bare tank is chosen to cultivate Luohan fish, and the bottom of the tank can be covered with a small amount of sand and gravel. Water quality: generally cultured in neutral soft water, change water frequently, the suitable water temperature is about 28 ℃. Filtration: use a filtration system to remove toxic substances from residual water. Lighting: use lamps and lanterns to illuminate for about 10 hours a day. Temperature control: control the water temperature at about 28 ℃.

1. Bottom sand

The main results are as follows: 1. it is generally chosen to raise the Luohan fish in a bare tank, because the Luohan fish has the nature of a large American sea bream that likes to turn the sand, especially in estrus, it will often turn the sand and gravel in the tank and cause the dirt in the bottom sand to be floated, so it is chosen to raise in a bare tank.

2. The bottom of the cylinder can be properly covered with a small amount of sand and gravel, especially with red and other colorful sand and gravel, which can not only adjust the water quality, but also make the color of the Luohan fish more bright. no matter what kind of sand and gravel is laid, do not affect the pH of the water quality, because some sand and gravel will release substances that make the water quality alkaline or acidic, which will affect the normal growth of Luohan fish, so avoid using it.

II. Water quality

The adaptability of Luohan fish is relatively strong, and the treatment of water quality is the same as that of other ornamental fish. It is necessary to treat the new water, then measure the water quality and water temperature, and then gradually put the Luohan fish fry into the new environment. Generally, the water quality condition of raising Luohan fish is neutral soft water, and the suitable water temperature is about 28 ℃.

3. Filtering

1. Luohan fish is a kind of fish with large food intake and high metabolism, so it is necessary to use a filtration system with large amount of filtered water and high efficiency to remove toxic substances in residual water. of course, there are many choices of filtration system, generally there are built-in filtration system and external filtration system.

2. The use of filter materials is also diversified, from dechlorite, filter cotton, biochemical balls, activated carbon, ceramic rings to sand and gravel. Generally, it is recommended to use a variety of filter materials, and pay attention to the aging and water treatment of filter materials at any time.

IV. Lighting

1. Proper lighting has a good effect on the color of Luohan fish. For Luohan fish raised in artificial environment, if proper lighting is not provided, its body color will lose its luster.

2. In general, there are all kinds of fish tanks and shaped lamps and lanterns available for the use of Luohan fish, which can be illuminated for an average of about 10 hours a day. Lighting for too long will make it easy to grow algae in the water, in addition to affecting viewing. It may even lead to anoxic death of Luohan fish.

Fifth, temperature control

The change of water temperature will cause Luohan fish to be infected with white spot disease, so in the areas where the air temperature can not be stabilized above 25 ℃, the tank where the temperature is not stable should be equipped with a thermostat to control the temperature at about 28 ℃, in case the water temperature suddenly drops below 25 ℃ and the disease occurs.
