How to Fix It
- Improve water quality by changing 25-30% of the water daily.
Ensure the new water is treated with a dechlorinator and has the same temperature and pH as the tank water.
- Administer an appropriate antibiotic or antiparasitic medication as directed by a veterinarian.
Follow the vet's instructions carefully for dosage and duration of treatment.
- Ensure the fish is receiving a balanced diet rich in vitamins and minerals.
Feeding a varied diet, including high-quality flake food and live or frozen foods, can support recovery.
- Remove any stressors from the tank, such as aggressive tankmates or poor water quality.
A stress-free environment is essential for healing.
