Causes of burnt tail of Luohan fish:

1. Long-term lack of trace elements in the body of Luohan fish or long-term irregular diet will cause burnt tail.

2. Changing water too frequently or changing too much water at one time will cause the pH of the water to be unstable. In addition, failure to maintain the water when changing the water and not removing the chlorine in the water can also lead to tail burn.

3. Water quality reasons can also cause Luohan fish to burn its tail. For example, if the water is not changed for a long time, food and feces in the water accumulate and breed bacteria for a long time, which will cause the water quality to be destroyed.

Methods to prevent Luohan fish from burning its tail:

1. Pay attention to nutritional balance when feeding. You can also add vitamin tablets to the feed to adjust the fish's physique. You should feed the fish regularly and quantitatively, so that you don’t want to be hungry every meal.

2. After feeding, the leftover feed, excrement and other pollutants of the fish should be cleaned up in time to ensure the cleanliness of the fish tank.

3. If you are raising fish in a new tank, you must wait until the nitrification system in the fish tank is established and perfected before adding new fish to the fish tank. You can also put fish into the tank in advance to test the water quality.

4. Each time you change the water, the amount should be moderate, preferably one-third or one-quarter. Be sure to trap the water for about three days before adding it to the fish tank.

5. Always check the pH of the water. You can use a pH tester to understand the pH in the fish tank to prevent tail burning. When adjusting the pH value or water temperature, it is necessary to adjust slowly, and it is best to adjust the difference by less than or equal to 0.5 each time.
