Guppies are loved by aquarium enthusiasts for their bright colors and elegant swimming posture, but tail rot is a common health problem during breeding. This article will provide you with detailed solutions based on the hot topics and hot content on the Internet in the past 10 days.
1. Common causes of rotten guppy tails

| Reason | Description |
|---|---|
| water quality issues | The ammonia nitrogen and nitrite content in the water is too high, or the pH value is unstable |
| bacterial infection | Bacterial diseases such as columnar disease (cotton wool disease) or tail rot |
| Traumatic infection | Fish become infected with bacteria after fights or scrapes |
| nutritional deficiencies | Not enough vitamin C or other essential nutrients |
2. Treatment measures for rotten guppy tails
| Treatment measures | Specific methods |
|---|---|
| Improve water quality | Change 1/3 of the water every day, keep the water temperature at 26-28°C, and use water quality stabilizer |
| drug treatment | Use oxytetracycline (5mg/L) or yellow powder (nitrofuracillin) medicated bath |
| Isolation treatment | Isolate sick fish individually to avoid infecting other fish |
| Supplement nutrition | Feed vitamin-rich feed and add a small amount of allicin |
3. Methods to prevent guppy tail rot
1.Maintain water quality regularly: Change the water at least 1-2 times a week, and the amount of water change should not exceed 1/3 each time. Use a water quality test agent to monitor water quality parameters.
2.Reasonable density breeding: To avoid overcrowding, it is recommended to keep 1 adult guppy per 10 liters of water.
3.Scientific feeding: Feed 2-3 times a day, and each feeding should be finished within 3 minutes to avoid residual bait from polluting the water quality.
4.Regular quarantine: Newly purchased fish should be isolated and observed for 1-2 weeks, and then placed in the main tank after confirming their health.

2. During the treatment period, the water quality should be kept stable and drastic changes in water temperature or pH value should be avoided.
3. If antibiotics are used, it is recommended to conduct a small-scale test first to avoid damage to the nitrification system.
4. During the recovery period, the water temperature can be appropriately increased by 1-2°C to help enhance the immunity of the fish.
6. Precautions
1. Avoid using multiple drugs at the same time to prevent drug interactions causing toxicity.
2. Reduce feeding during treatment to avoid indigestion from aggravating the condition.
