Steps to Save A Dying Betta Fish

If you notice that your Betta fish is showing signs of distress or illness, it’s important to take immediate action to try and save it. Here are some steps you can take to help save a dying Betta fish:

Assess the Water Parameters

Test the water quality in your Betta fish tank using a reliable water testing kit. Check the temperature, pH, ammonia, nitrite, and nitrate levels. Make sure the water temperature is within the suitable range for Betta fish (76°F to 82°F or 24°C to 28°C) and that the water parameters are within the acceptable range. Perform a water change if necessary to improve water quality.

Check for Signs of Illness

Observe your Betta fish closely and look for any visible signs of illness or disease, such as loss of appetite, lethargy, fin rot, bloating, white spots (indicating ich), or unusual behavior. Identifying the specific issue can help determine the appropriate treatment.

Quarantine If Necessary

If you have other fish in the tank, it’s important to isolate the sick Betta fish in a separate quarantine tank to prevent the spread of any potential diseases.

Adjust the Tank Environment

Ensure that the tank setup is appropriate for Betta fish. Check the water flow and make sure it’s not too strong, as Betta fish prefer calm water. Provide hiding places and plants for the fish to feel secure.

Perform Regular Water Changes

Maintain good water quality by performing regular partial water changes. This helps remove toxins and replenish the tank with fresh, clean water. Aim for a 25% water change every week or as needed to keep the water parameters stable.

Treat the Fish If Necessary

If you suspect a specific illness or disease, consult a veterinarian or a knowledgeable fish expert for proper diagnosis and treatment options. Follow their guidance and administer any prescribed medications as instructed.

What are the Causes of Betta Fish sickness?

There are several factors that can contribute to a Betta fish becoming sick. Here are some common causes of Betta fish sickness:

Poor Water Quality

One of the leading causes of fish illnesses is poor water quality. Ammonia, nitrite, and nitrate build-up can be toxic to fish, leading to stress and increased susceptibility to diseases. Overcrowding, inadequate filtration, infrequent water changes, and overfeeding can all contribute to poor water quality.

Inadequate tank conditions

Betta fish require specific tank conditions to thrive. Inappropriate water temperature, incorrect pH levels, lack of proper filtration, and improper tank size can all lead to stress and weakened immune systems in Betta fish, making them more susceptible to diseases.


Stress can compromise a Betta fish’s immune system, making it more prone to illnesses. Stressful conditions can include aggressive tankmates, excessive handling, sudden changes in water parameters, inadequate hiding places, or a lack of stimulation in the tank environment.

Poor Nutrition

Betta fish require a balanced and nutritious diet to maintain their health. Feeding low-quality or inappropriate food, overfeeding, or not providing a varied diet can lead to nutritional deficiencies and weakened immune systems.

Lack of Quarantine

Introducing new fish, plants, or decorations without proper quarantine can introduce diseases or parasites to the tank, potentially infecting the Betta fish.

Pre-existing Health Conditions

Betta fish can suffer from pre-existing health conditions, such as genetic disorders or weakened immune systems due to poor breeding practices. These conditions can make them more susceptible to illnesses.

Pathogenic Infections

Bacteria, fungi, and parasites can cause infections and diseases in Betta fish. These infections can be introduced through contaminated water, live food, or poor hygiene in the tank.


It’s heartbreaking for any pet owner to see their little fishy suffering due to various reasons. However, with proper care, medicine, and attention, betta fish can be nursed back to health and kept alive for years. We have learned several effective solutions and death prevention techniques in this post.

Regular water changes, a clean tank, and a suitable environment are critical factors for a healthy betta fish life. Choosing the right food, and adding aquarium salt and medications can also help them recover. Remember, every betta fish is different and may require a different healing approach.

It’s essential to monitor their behavior and health regularly. By following these methods, you can ensure your beloved pet’s long and happy life. Betta fish can be lovely and playful creatures to have around; with proper care, they can become your perfect companion.
