Recognizing Sick Betta Fish Behavior & How To Help a Sick Betta Fish
Behavioral changes in betta fish are often the first indicators of health issues. Vigilant observation is vital to early detection and treatment. Here is some betta fish behavior before death to look out for:
- Bloat – Can be caused by Dropsy, overfeeding, constipation, a diet lacking in variety, or infections.
- Lethargy and decreased activity levels
- Refusal to eat or reduced appetite
- Difficulty swimming, such as floating on one side or sinking to the bottom of the tank
- Betta losing colors or loss of vibrancy
If your betta is really sick… do not put it down until you are sure it cannot be saved. A lot of times, all it takes is a few tweaks to improve their health.

No Appetite | Disinterest in food | Temperature fluctuations, advanced age, stress, illness | Investigate and rectify underlying issues, temperature control |
Tail Biting | Self-inflicted injuries to the tail | Environmental stress, lack of stimulation | Enrich habitat with plants/toys, monitor for stress signs |
Columnaris
Also known as “cotton mouth,” Columnaris is a bacterial infection that presents as white or grayish spots and patches on the body and around the mouth and gills. If not addressed promptly, it can rapidly deteriorate the health of your fish.
- Tips:
- Quarantine the affected fish immediately to prevent the spread of bacteria.
- Treat the water with antibacterial medicine designed explicitly for Columnaris. Furan-2 and Kanamycin are effective options.
- Maintain high water quality through regular changes and removing uneaten food and debris.
Dropsy
Dropsy is not a disease on its own but a symptom of underlying issues, often kidney failure. It manifests as severe bloating and raised scales, giving a pinecone-like appearance. Read more on Dropsy here.
- Tips:
- While difficult to treat, early detection improves chances. Begin with isolating the affected betta.
- Offering a warm bath with Epsom salt can help reduce fluid retention.
- Consultation with a veterinarian for possible antibiotic treatments is recommended, though recovery chances remain slim.
Ich/Ick
Ichthyophthirius multifiliis, commonly known as Ich or Ick, is a parasitic infection recognizable by white, grain-like dots covering the betta fish’s body and fins. It’s highly contagious and stressful for the fish, if you suspect the parasite in your betta read on…
- Tips:
- Increase the tank’s temperature gradually to 86°F over 24 hours to speed up the parasite’s life cycle.
- Add aquarium salt at 1 teaspoon per gallon of water to help the fish produce more slime coating, offering protection against the parasite.
- Use over-the-counter Ich treatment, following the instructions carefully. Treatment should continue for at least a week to ensure all parasites, including those in the larval stage, are eradicated.
Fin & Tail Rot
Fin rot, a common affliction in betta fish, is characterized by fraying, discoloration, and receding edges on the fins. It’s often caused by poor water quality or a bacterial infection. Read more on fin rot here.
- Tips:
- Regularly clean the tank and change the water to improve conditions.
- Treat the tank with antibacterial medications, such as Maracyn or tetracycline-based products, to combat bacterial causes.
- For fungal causes, antifungal treatments like Pimafix can be effective.
Velvet
This parasitic disease, caused by the dinoflagellate parasite, presents as a gold or rust-colored dusting on the betta’s body. Affected fish may scratch against objects due to irritation.
- Tips:
- Quarantine the infected fish to prevent spreading to tank mates.
- Treat the tank with copper-based medications or malachite green, following dosage instructions precisely.
- Reduce lighting in the tank, as the parasite thrives in well-lit conditions.
Popeye
Popeye is an infection that causes one or both eyes to bulge outward. It can result from bacterial infections or physical injuries.
- Tips:
- Improve water quality to reduce the chance of infection.
- In cases of bacterial popeye, antibiotics can be effective.
- For injury-induced popeye, ensure the tank is safe and free of sharp decorations that could harm the fish.
Swim Bladder Disease
Swim bladder disease affects the fish’s ability to control buoyancy, resulting in floating or sinking. Overfeeding, constipation, or water quality issues might be the cause. Read all about swim bladder here.
- Tips:
- Ensure the water is at an appropriate temperature and quality to support digestion and reduce stress.
- Avoid overfeeding and provide a diet with variety to prevent future occurrences.
- Read about betta fish care, and use their guidebook for treatment
Tumor
Tumors can appear as abnormal growths on the body or inside the betta. They may be benign or malignant and can vary in treatability.
- Tips:
- Little can be done at home for tumors; maintaining a stress-free environment is critical.
- Regularly monitor the tumor for changes and consult a veterinarian specialized in fish if significant changes occur.
Septicemia
Septicemia is a systemic bacterial infection that causes red streaks or spots on the body, lethargy, and loss of appetite. It is often fatal if not treated promptly.
- Tips:
- Immediate antibiotic treatment is necessary. Consult a vet for the best course of action.
- Improve tank conditions to prevent future infections. Regular water changes and monitoring for stressors are essential.
Constipation
A common issue due to overfeeding or a lack of dietary fiber, constipation is evident if your betta has a swollen belly and difficulty defecating.
- Tips:
- Fasting the fish for a few days can help clear its system.
- Feeding a small, cooked, peeled pea can aid digestion and relieve constipation.
Lethargy
If your betta is less active than usual, it could be due to cold water, poor water quality, or stress.
- Tips:
- Ensure the water temperature is stable and within the ideal range for bettas (76-81°F).
- Test the water regularly and keep the tank clean to prevent stress from poor water conditions.
No Appetite
A betta might lose its appetite for various reasons, including stress, water temperature changes, or illness.
- Tips:
- Investigate and correct any environmental stressors or water quality issues.
- Try offering different types of food to stimulate appetite, ensuring they are appropriate for bettas.
Tail Biting
Stress or boredom can lead bettas to bite their tails, causing injury and potentially leading to fin rot.
- Tips:
- To prevent boredom, provide ample enrichment in the tank, such as plants and hiding places.
- Regularly change the layout of the tank to offer new stimuli.
Prevention Strategies
The cornerstone of betta fish care is prevention. Many common ailments can be avoided with the correct practices:
- Water Quality: Regularly test and maintain the parameters (ammonia, nitrite, nitrate levels, pH, and temperature) within the ideal range for betta fish.
- Nutrition: Feed your betta a varied diet, avoiding overfeeding. Mixing high-quality pellets, frozen, and live foods can provide balanced nutrition.
- Environmental Enrichment: Keep your betta stimulated with a well-decorated tank that includes hiding spots and plants. A bored betta is a stressed betta, more susceptible to illness.
- Regular Monitoring: Regularly observe your betta for any signs of distress or disease. Early detection is critical to effective treatment.
Caring for a betta fish is a rewarding endeavor that comes with its set of challenges. Understanding the signs of common diseases and how to address them is crucial for any betta owner. By staying vigilant and providing a clean, enriching environment, you can enjoy your betta’s beauty and companionship for years to come.
