Bettas are known for their vivid colors and lively personalities, but when they’re nearing the end of their life, their behavior changes dramatically. Look for these critical signs:
Lethargy and Decreased Activity – The First Signs of Trouble
When a once-active Betta spends more time lying at the bottom of the tank or floating listlessly, it’s often a sign of declining health. This can be caused by poor water conditions, stress, or underlying illness.
What to Do:
- Test water parameters for ammonia, nitrites, and pH.
- Maintain water temperature between 78-80°F.
- Add aquarium salt to reduce stress and discomfort.
Loss of Appetite – A Disturbing Indicator
If your Betta suddenly refuses food or spits it out, it could indicate stress, infection, or digestive problems. Bettas typically have a strong appetite, so ignoring food is a significant warning sign.
What to Do:
- Isolate the Betta in a separate hospital tank.
- Offer soft, easy-to-digest foods like brine shrimp or daphnia.
- Administer anti-parasitic or anti-bacterial treatments if necessary.
Clamped Fins – A Clear Sign of Stress or Sickness
Healthy Betta fins fan out gracefully. When they stay clamped close to the body, it usually signals distress or infection. Stress from poor water conditions, parasites, or bacterial infections can cause this.
What to Do:
- Improve water quality through frequent water changes.
- Apply a stress coat to the water to soothe irritated skin.
- Treat with antibacterial medication if fins appear frayed or deteriorating.
Erratic Swimming and Floating Issues – Is Your Betta Losing Control?
A Betta struggling to swim properly may have swim bladder disease. This condition can cause them to float sideways, sink, or wobble uncontrollably.
What to Do:
- Fast the Betta for 24 hours to alleviate constipation.
- Lower the water level to make swimming less strenuous.
- Add Indian almond leaves to calm the fish and reduce inflammation.
Labored Breathing – Gasping for Air
Gasping at the surface or rapid gill movement often indicates that the Betta is struggling to get enough oxygen. This could be due to ammonia poisoning, poor water quality, or a bacterial infection.
What to Do:
- Perform a 50% water change to reduce toxins.
- Increase oxygenation with a gentle air stone.
- Treat for gill parasites or bacterial infections as needed.
Color Fading – When Vibrance Turns to Dullness
A once-vibrant Betta that appears dull or pale is likely under stress or suffering from illness. This symptom is common in aging fish but can also signal severe stress.
What to Do:
- Maintain stable water conditions to minimize stress.
- Offer nutrient-rich foods to strengthen their immune system.
- Remove aggressive tank mates to prevent bullying.
White Patches, Fungal Growths, or Parasites – The Signs of a Severe Infection
If your Betta has white cotton-like patches, small spots, or unusual skin lesions, it may be suffering from a fungal infection, Ich, or other parasites.
What to Do:
- Increase the water temperature to 82°F to inhibit parasites.
- Apply antifungal or antiparasitic treatments as needed.
- Isolate the Betta to prevent the spread of infection.
Fin Rot – The Silent Killer
Fin rot causes the edges of the fins to fray and blacken. It is typically caused by bacteria in unclean water and can rapidly deteriorate a Betta’s health.
What to Do:
- Isolate the Betta in a hospital tank.
- Administer antibacterial medication.
- Perform regular water changes to prevent further infection.
Loss of Balance – The Last Cry for Help
If your Betta is floating sideways, upside down, or struggling to stay upright, it may have swim bladder disorder or neurological issues.
What to Do:
- Fast for 24 hours to relieve constipation.
- Administer Epsom salt baths to reduce swelling.
- Lower the water level to minimize exertion.
How to Comfort a Dying Betta Fish – Creating a Peaceful End
If your Betta shows multiple signs of decline and treatment isn’t working, it’s time to focus on comfort care. Here’s how to make their final days as calm and pain-free as possible. Here’s how to provide a calm and peaceful environment:
- Reduce water flow to prevent stress.
- Offer soft, easy-to-digest foods like frozen brine shrimp.
- Keep the tank dimly lit to minimize stress.
- Maintain a consistent water temperature to avoid shocks.
Is Euthanasia the Kindest Option? When to Let Go
If your Betta’s condition continues to worsen despite treatment, humane euthanasia may be the kindest choice to prevent further suffering. The most accepted method is using clove oil, which induces a painless sleep.
Preventing Betta Fish Decline – How to Keep Your Betta Thriving

- Test water parameters weekly to catch early signs of water quality issues.
- Maintain a stable temperature and use a heater to prevent temperature shock.
