Axolotls are fascinating, quirky creatures, and owning one feels like having a tiny, underwater dragon. But like any pet, they can face health issues.
If you’re an axolotl enthusiast, you know how important it is to keep your little friend happy and healthy. Spotting problems early and knowing how to prevent them can make a huge difference in their quality of life.
Let’s explore the most common health challenges axolotls face and what you can do to help them thrive.
Poor Water Quality: A Silent Threat

Good water quality is essential for axolotls. When it’s off, your axolotl can suffer from various health problems. Poor water conditions often lead to stress, infections, or even fatal illnesses.
Hydrocoelom is the most common health issue in axolotls, accounting for 27.5% of cases observed in a study of 97 pet axolotls over an 82-month period.
Signs of Poor Water Quality
If your axolotl seems lethargic, loses its appetite, or develops fungal growths, it’s time to test the water. Common culprits include ammonia, nitrite, and nitrate spikes. Axolotls are sensitive to these toxins, which can quickly harm them if left unchecked.
Preventing Water Quality Issues
- Regular Water Testing: Use aquarium test kits to monitor ammonia, nitrites, and nitrates. Keep ammonia and nitrites at 0 ppm and nitrates under 20 ppm.
- Proper Filtration: A gentle filter reduces waste buildup without stressing your axolotl.
- Frequent Water Changes: Replace 20-30% of the water weekly to maintain balance.
Maintaining stable water quality is the first step to avoiding many other health issues.
Fungal Infections: White Fluff on Your Axolotl
Fungal infections are one of the most noticeable health issues. They often appear as white, fluffy patches on the skin or gills. These infections usually occur in stressed or injured axolotls.
Hyperthermia occurs when water temperatures exceed 24°C (75°F), leading to symptoms such as loss of appetite and floating behavior in affected axolotls.
Causes of Fungal Infections
Fungus thrives in poor water conditions, sudden temperature changes, or when an axolotl’s immune system is weak. Injuries from sharp tank decorations or rough handling can also increase the risk.
Treating and Preventing Fungal Infections
- Salt Baths: Place your axolotl in a separate container with a saline solution (use non-iodized salt). This helps kill the fungus without harming your pet.
- Tank Cleanliness: Keep the tank clean and free of debris.
- Optimal Temperature: Maintain water temperature between 60-64°F to avoid stressing your axolotl.
Taking care of your axolotl’s environment can significantly reduce the chances of fungal infections.
Parasites: Unwanted Guests
Axolotls can sometimes pick up parasites, especially if live food or unclean water sources are used. Parasites can cause issues like weight loss, bloating, and skin irritations.
Common Parasites in Axolotls
- External Parasites: These often attach to the gills or body, causing irritation.
- Internal Parasites: Worms or protozoa in the gut can lead to weight loss and lethargy.
How to Handle Parasites
- Quarantine New Additions: Always quarantine new axolotls or live food before introducing them to the main tank.
- Veterinary Help: For severe infestations, consult an aquatic vet for proper medication.
- Preventative Measures: Avoid feeding wild-caught or unclean live food.
Parasites are preventable with good hygiene and careful food choices.
In captivity, axolotls can live up to 15 years, with an average lifespan of 10 to 12 years when properly cared for, compared to only 5 to 6 years in the wild due to environmental threats.
Injuries: Cuts, Bites, and Tank Hazards
Axolotls are delicate and can easily get injured in poorly designed tanks or during feeding. Injuries not only hurt your axolotl but can also lead to infections.
Common Causes of Injuries
- Sharp Decorations: Rocks or tank accessories with rough edges can scrape their skin or gills.
- Aggressive Tankmates: Axolotls should be kept alone or with others of similar size to prevent biting.
- Improper Handling: Mishandling can bruise or damage their sensitive bodies.
Preventing and Treating Injuries
- Safe Tank Setup: Use smooth decorations and avoid sharp objects in the tank.
- Isolate Injured Axolotls: Move them to a clean tank with fresh water to prevent infection.
- Healing Aids: Products like stress coat additives can help promote healing.
Keeping their environment safe and stress-free reduces the risk of injury.
Bacterial Infections: A Hidden Danger
Bacterial infections in axolotls can cause symptoms like red patches, open sores, or lethargy. Left untreated, these infections can quickly worsen.
Causes of Bacterial Infections
These infections often result from poor water quality, untreated injuries, or contaminated food. Warm water (above 70°F) can also encourage bacterial growth.
How to Combat Bacterial Infections
- Cool, Clean Water: Maintain water temperature below 68°F and ensure pristine conditions.
- Topical Treatments: Use aquarium-safe antibiotics or consult a vet for severe cases.
- Prevention: Remove uneaten food and debris promptly to avoid bacterial buildup.
Acting quickly at the first sign of infection can save your axolotl’s life.
Impaction: A Blocked Digestive System
Impaction happens when your axolotl eats something it can’t digest, like gravel or large food items. It can lead to serious complications if not addressed.
Signs of Impaction
If your axolotl looks bloated, stops eating, or has difficulty swimming, it might be impacted. You might also notice a lack of waste in the tank.
Preventing and Treating Impaction
- Avoid Small Gravel: Use sand or a bare-bottom tank instead of gravel to prevent accidental swallowing.
- Right Food Size: Feed appropriately sized foods like worms or pellets.
- Cool Water Therapy: Lowering the water temperature can sometimes help pass the blockage naturally.
Prevention is key, but early action can resolve impaction before it becomes life-threatening.
Floating Syndrome: Trouble Staying Down
Floating syndrome isn’t a disease but often indicates something’s wrong. Axolotls float when they have gas buildup, impaction, or stress.
Why Axolotls Float
- Diet Issues: Overfeeding or improper food can cause gas.
- Water Conditions: High nitrates or fluctuating temperatures stress axolotls.
- Infections: Certain bacterial infections can lead to buoyancy problems.
Helping Your Floating Axolotl
- Check Water Parameters: Fix any issues with ammonia, nitrites, or nitrates.
- Adjust Feeding Habits: Feed smaller portions and remove uneaten food quickly.
- Isolate If Needed: If stress or illness is suspected, move your axolotl to a clean, quiet tank.
Floating often resolves itself with minor adjustments, but persistent cases may need vet attention.
Stress: The Root of Many Issues
Stress weakens your axolotl’s immune system, making it prone to illnesses. It’s one of the most common underlying causes of health problems.
Common Stress Triggers
- Bright Lights: Axolotls prefer dim environments.
- Tankmates: Aggressive or overly active tankmates can stress them out.
- Fluctuating Conditions: Sudden changes in temperature, water quality, or handling routines.
Reducing Stress in Axolotls
- Provide Hiding Spots: Use plants or caves to create sheltered areas.
- Stable Conditions: Keep water parameters consistent and within safe ranges.
- Gentle Handling: Avoid frequent handling and ensure it’s done correctly when necessary.
A stress-free axolotl is a healthy axolotl.
The Importance of Regular Check-Ups
Even with great care, it’s important to regularly observe your axolotl for any signs of illness. Early detection often makes treatment easier and more effective.
What to Look For
- Behavior Changes: Lethargy, reduced appetite, or unusual swimming patterns.
- Physical Signs: Fungal patches, redness, bloating, or visible injuries.
- Water Quality: Regularly test and adjust water conditions as needed.
Building a Routine
Make it a habit to spend a few minutes each day observing your axolotl. Routine check-ups help you catch small issues before they escalate.
Keep Your Axolotl Healthy and Happy
Axolotls are hardy, but they’re not invincible. By focusing on clean water, proper nutrition, and a safe environment, you can prevent most health problems. Regular care and observation go a long way in ensuring your axolotl thrives.
When in doubt, always consult a vet experienced in aquatic animals. Your axolotl depends on you, so make their health a top priority!
