Owning an axolotl is a bit like having a tiny aquatic dragon in your home. These fascinating creatures captivate everyone with their unique features and quirky personalities.
But, if you’ve ever found yourself wondering, “Is my axolotl healthy?” you’re not alone. Knowing what to look for is key to ensuring your axolotl stays happy and thriving.
Let’s break it down in simple, friendly terms so you can confidently care for your little aquatic buddy.
Bright Eyes and Clear Gills: The Basics of Axolotl Health

Healthy axolotls have vibrant, alert eyes and gills that stand out. Their eyes should be clear and bright, without any cloudiness or discoloration. If your axolotl has dark-colored eyes, the color will look rich and even. For lighter-colored eyes, they should appear clean, not dull or milky.
Adult axolotls typically weigh between 2.1 to 8 ounces.
The gills are another big indicator of health. Healthy gills are fluffy and vibrant, with a full, feathery appearance.
Depending on your axolotl’s color, they might be red, pink, or even a soft golden hue. Pay attention to the filaments; they should move gently in the water, showing that your axolotl is breathing normally.
What If the Gills Look Dull or Shrink?
Shrinking or dull gills could mean your axolotl is stressed or living in poor water conditions. Check the water temperature, ammonia levels, and filtration system right away. Stressed axolotls often recover once their environment is fixed.
Smooth, Soft Skin Without Blemishes
Your axolotl’s skin is like a window into its overall health. A healthy axolotl will have smooth, soft skin that’s free from any wounds, spots, or discoloration. The skin may have a natural sheen or pattern, depending on the morph (color variation), but it shouldn’t look patchy or damaged.
Signs of Skin Problems to Watch For
If you notice white, fuzzy patches, they could indicate a fungal infection. Red sores or irritated areas might mean there’s an injury or bacterial issue. Both conditions often result from poor water quality, so keeping the tank clean and balanced is critical.
As such, the axolotl is estimated to have suffered a population loss of at least 80% over the past three generations, classifying the species as Critically Endangered under the IUCN Red List.
Tips for Maintaining Healthy Skin
- Use dechlorinated water: Tap water with chlorine can irritate your axolotl’s sensitive skin.
- Keep the tank cool: Warm water leads to stress and skin problems. Aim for a temperature between 60–68°F (15–20°C).
- Avoid rough decorations: Decorations with sharp edges can scrape their skin.
A Strong Appetite and Steady Activity
Axolotls are natural hunters, and their appetite says a lot about their health. A healthy axolotl will show interest in food and eat eagerly during feeding time. While they’re not overly active like some fish, you should notice them moving around the tank occasionally or exploring their environment.
What If Your Axolotl Refuses to Eat?
Skipping a meal once in a while isn’t uncommon, but refusing food for several days is a red flag. It could indicate stress, illness, or problems with water quality. Check for signs like bloating or lethargy, and test the water parameters to rule out environmental issues.
Axolotls can live between 10 to 15 years in captivity under optimal care conditions.
Foods That Keep Axolotls Healthy
Offer a mix of protein-rich foods, like:
- Earthworms (a favorite!)
- High-quality axolotl pellets
- Frozen bloodworms or brine shrimp
Feed every 2–3 days, and make sure to remove uneaten food to keep the tank clean.
Normal Movement and Posture
Axolotls have a unique way of moving that’s both graceful and clumsy. A healthy axolotl will have smooth, coordinated movements, whether swimming or resting. You’ll notice them floating, walking on the tank bottom, or sometimes perching on a plant or rock.
Signs of Stress or Illness in Movement
If your axolotl is thrashing, floating upside down, or struggling to stay upright, it could mean there’s an issue. Floating isn’t always a problem—sometimes they gulp air—but consistent floating or sinking could mean they’re struggling with gas or stress.
How to Help With Movement Issues
- Check water flow: Axolotls prefer calm water. Strong currents can make them struggle to swim.
- Test the water: High ammonia or nitrate levels often cause stress and odd behaviors.
- Give them hiding spots: Axolotls feel secure when they have caves or decorations to retreat into.
A Well-Maintained Tail and Limbs
The tail and limbs are essential parts of your axolotl’s anatomy, and they should always look strong and intact. A healthy axolotl has a straight tail with no kinks or bends, and their legs should be well-formed and free of swelling or damage.
Why Is a Kinked Tail a Concern?
A kinked or bent tail often signals stress or illness. It might happen if the water quality is poor or if your axolotl feels threatened. Sometimes it can be an early sign of a more serious health issue, so address any environmental concerns immediately.
Keeping Limbs Healthy
- Avoid overcrowding the tank. Aggressive tank mates or other axolotls may nip at limbs.
- Provide a spacious tank. A cramped tank can lead to stress and injuries.
Axolotls can regenerate their limbs, but consistent injuries mean there’s a bigger problem in their environment.
Clear Tank Conditions = A Happy Axolotl
Your axolotl’s health is directly tied to its environment. Crystal-clear, well-maintained water is one of the most important things you can provide. Healthy axolotls thrive in clean water with stable conditions, including temperature, pH, and low ammonia levels.
How to Maintain Perfect Tank Conditions
- Perform weekly water changes: Replace about 20–30% of the water to keep it fresh.
- Test the water regularly: Check for ammonia, nitrite, and nitrate levels. These should always be at zero or close to it.
- Use a sponge filter: These are gentle on axolotls and keep the water clean.
Why Water Temperature Matters
Axolotls are cold-water creatures. Warm water can stress them out, causing poor appetite, dull gills, and even illness. Always monitor the temperature with a reliable thermometer.
Social Signs of a Happy Axolotl
Axolotls aren’t social creatures in the traditional sense, but their behaviors can tell you a lot. A content axolotl will explore its tank, interact with its environment, and occasionally respond to you when you approach the tank.
What If Your Axolotl Seems Inactive?
While they do spend a lot of time resting, excessive inactivity might mean something’s wrong. Look for other signs like poor appetite or abnormal gills to figure out if there’s an issue.
Can Axolotls Live With Tank Mates?
It’s possible, but tricky. Many axolotl owners prefer to keep them alone because they’re prone to accidental injuries from other creatures. If you choose to add tank mates, opt for peaceful species that won’t nip at your axolotl’s gills.
When to Seek Help From a Vet
Sometimes, even with the best care, your axolotl might show worrying signs. If you notice persistent issues like refusal to eat, rapid weight loss, or severe skin problems, consult an aquatic veterinarian. Early intervention often prevents minor problems from becoming serious.
Finding a Vet Who Understands Axolotls
Not all vets are experienced with axolotls, so look for one with expertise in exotic or aquatic animals. Bring water samples from your tank when you visit—it helps the vet pinpoint potential environmental issues.
The Secret to a Thriving Axolotl
Caring for a healthy axolotl isn’t complicated, but it does take consistent effort. By focusing on clear water, proper food, and a stress-free environment, your axolotl can live a long, happy life.
Remember, a healthy axolotl is active, alert, and eager to eat, with smooth skin, vibrant gills, and no signs of stress. If you notice anything off, small adjustments often make a big difference.
Take the time to observe your axolotl daily—it’s the best way to catch problems early and enjoy the unique personality of this fascinating pet. Keeping your tank conditions perfect and watching for signs of health will help your little aquatic friend thrive for years to come!
