A water tank of 1 m should be used to raise arhat fish, and the water depth should be more than 40 cm. Bottom sand should be laid at the bottom of the pool, and coral sand or volcanic rocks should generally be used. The water quality should be neutral and the temperature should be kept at 28-30℃. Feed should be selected according to the size of fish in daily feeding. Red worms are mainly fed during the fry period. Older ones can be fed frozen river shrimps, or they can make their own beef heart burgers. Pay attention to observation at ordinary times If they are found to be sick, they need to be heated in time and treated with salt, or the sick fish should be taken out and treated with medicinal bath. First, the living environment generally requires a fish tank with a water depth of about 1 m, and the water depth should be kept above 40 cm, so that there is enough room for activities. Fish tanks can be covered with bottom sand, usually coral sand or volcanic rocks, which can adjust the pH and induce its coat color. In addition, this kind of fish is suitable for living in neutral water, and the ph value should be kept between 6.8 and 7.5. Acidic water will cause tail burning and affect its ornamental value. Because it is a tropical fish, the water temperature should be kept constant at 28-30℃. Once it changes, it is easy to get sick.

Second, the daily feeding of Luohan fish should be fed with different foods at different stages. In the fry stage, the food is mainly red worms, and when it grows to more than 6 cm, it can be supplemented with a little frozen river shrimp. In the sub-growth stage, you need to change your mouth, there are many feeds to choose from, and you need to pay attention to the feeding amount. Generally, fish belly is the best. Besides buying feed, you can also make your own feed. For example, you can mix beef heart and shrimp to make a beef heart burger, put it in the refrigerator and cut it into pieces when you need to feed it. In addition, if you feed live animals, you need to disinfect them.

Third, disease prevention Luohan fish will inevitably get sick during the feeding process, and it needs timely treatment after the onset. If you have leukoplakia, you can sterilize it by raising the temperature, or you can add indigo solution for medicinal bath. If you have water mold, you need to soak it in formalin or salt solution for a period of time. If you suffer from squamatosis, you need to put the sick fish in a medical aquarium and soak it in nitrofurazone solution. If you catch a cold, add new water slowly when you need to change water. When you release fish, the temperature difference should not exceed 3℃, and pay attention to the temperature change.
