What’s Wrong with My Betta Fish? Pale, Lethargic, Damaged Fins & Crooked Body

Dear VetBabble,

My betta fish is really sick, and I am having a hard time diagnosing his condition. He is floating at the surface, is very pale, lethargic, his fins are damaged and his body is crooked. I found some yellow powdery looking stuff in the tank, so I thought he had velvet. I also thought he might have Swim Bladder Disease (SBD) since he is crooked. I have placed him in a 2-gallon ‘quarantine’ tank and used Jungle fungus clear in the tank. I have also fed him peas, but he’s not getting much better. What should I do to help my fish?

Section 1: Testing the Water Quality

Understanding your betta fish’s condition requires a logical and thorough approach. First and foremost, submit a water sample for quality testing. Most pet stores will do this for free or for a nominal fee. Clinical examinations for sick fish should always include a water quality check, even if you have done so already. It is essential to use a quality test kit that measures NH4, NO2, and NO3. High ammonia levels and pH imbalances may be responsible for your fish’s symptoms. Oxygen concentration and the quality of the filters should also be determined.

Section 2: Identifying and Treating Infections

If the water quality is good and there are no major imbalances, your fish should be examined for any signs of bacterial or fungal infections. Consult a veterinarian that specializes in fish care for proper diagnosis and treatment. This is crucial, as different infections require specific treatments. For example, our articles on Tropical Fish Care Guide and Goldfish Care 101: How to Keep a Pet Goldfish offer helpful information on maintaining a healthy aquatic environment and addressing common health issues in fish.

It’s important to note that fish can be affected by various parasites, such as velvet and ich. These parasites can cause symptoms similar to those you’ve described. Make sure to read our articles on identifying and treating parasites in dogs and cats like Does My Dog Have Mange? and Ringworm in Cats – Learn the Signs and How to Treat as they provide useful insights that may also apply to fish parasites.

Section 3: Continuing Care and Support

As you continue to care for your betta fish, monitor his progress closely. Sometimes, improvements may be gradual, and patience and consistent care are required. Ensure that you maintain the water quality in the quarantine tank and provide your fish with a nutritious diet suitable for betta fish.

If your fish’s condition worsens or does not improve despite following the advice and treatments given, consult your veterinarian again to re-evaluate the situation. It is essential to be proactive and not hesitate to reach out for professional advice.

In conclusion, it is crucial to test water quality, investigate bacterial or fungal infections, and consult a specialist in fish care to ensure your betta fish receives the best treatment possible. We hope this information is helpful and encourage you not to hesitate to contact us again if you have any more questions or concerns regarding your betta fish’s health.
