1. Perform water tests: Check the water parameters in the original tank to ensure they are suitable for guppies. Look for any potential causes of stress or illness, such as high levels of ammonia, nitrites, or nitrates.
2. Provide clean, conditioned water: In the separate tank, use conditioned water that is free of chlorine and chloramines. Guppies are sensitive to water quality, so make sure the water temperature is maintained at a suitable level (around 72-78°F / 22-26°C).
3. Add aquarium salt: Epsom salt (magnesium sulfate) can help reduce inflammation and aid in the healing process. Add 1 teaspoon of aquarium salt (not table salt) per gallon of water in the separate tank.
4. Offer nutritious food: Ensure that the guppy has access to a variety of high-quality foods, such as live or frozen brine shrimp, daphnia, and flakes or pellets specifically formulated for guppies.
5. Maintain proper tank conditions: Provide the guppy with a calm, stress-free environment in the separate tank. Avoid overcrowding and provide plenty of hiding spots to help the guppy feel secure and reduce stress.
6. Monitor the guppy's condition: Keep a close eye on the guppy's progress. If its condition worsens or shows no improvement within a few days, consult a veterinarian or experienced aquarist for further advice.
Remember, the exact course of action may vary depending on the severity of the tail loss and the guppy's overall health. It's important to provide proper care and monitoring to help your guppy recover.
