Why Is My Axolotl Floating

You walk over to your axolotl’s tank and notice something odd—your little buddy is floating. At first, it might seem cute or funny, but then you start to worry. Is something wrong?

Don’t panic! Floating is a common behavior in axolotls, and it doesn’t always mean trouble. Sometimes it’s harmless, but other times it’s a sign you need to step in.

Let’s go through why axolotls float, what could be causing it, and how you can help your aquatic friend feel comfortable again.

What Causes Axolotls to Float?

Axolotls float for a mix of reasons. Some are completely normal, like gulping air, but others could signal a problem. You’ll need to figure out what’s going on by observing their behavior, checking water conditions, and considering their diet. Axolotls can’t tell you how they’re feeling, so it’s up to you to spot the clues.

Female axolotls can lay between 300 to 1,000 eggs at a time, but their populations have drastically declined despite this reproductive capability.

Buoyancy Issues

One of the most common reasons for floating is a buoyancy problem. Axolotls rely on their lungs and a specialized organ called the swim bladder to balance themselves in the water. If too much air gets trapped in their body, they can float unexpectedly.

• Air swallowing: Axolotls sometimes gulp air at the surface, especially if they’re curious or exploring. This isn’t harmful unless it happens a lot.
• Swim bladder problems: Though less common, issues with their swim bladder can cause uncontrollable floating. This may result from injury, infection, or a genetic defect.

Water Quality Problems

Poor water quality is a top cause of stress in axolotls. When water conditions aren’t right, your axolotl’s behavior changes, including increased floating. Make sure your tank is properly maintained.

Check for:

• Ammonia, nitrite, and nitrate levels: High levels irritate your axolotl and can lead to floating or gas buildup in their body.
• Temperature fluctuations: Axolotls thrive in water between 60–68°F. Warmer water stresses them, which might make them float more.
• pH imbalances: Axolotls prefer a pH between 6.5–8. Any major swings can impact their comfort.

Digestive Problems

Axolotls are opportunistic eaters, but their digestion can be tricky. If they overeat or swallow something they shouldn’t, they may struggle to stay grounded.

Common causes include:

• Overfeeding: Feeding too much or too often leads to bloating, which can trap air inside their digestive system.
• Impaction: If your axolotl eats gravel, sand, or other tank debris, it can cause blockages. This is a serious condition that often results in floating.

Estimates suggest there are only between 50 to 1,000 adult axolotls remaining in the wild.

Stress or Illness

Axolotls can float due to stress or health problems. Look for other signs, like lack of appetite, redness, or lethargy, to determine if floating is part of a bigger issue.

Some health concerns include:

• Infections: Bacterial or fungal infections can cause swelling, making it harder for your axolotl to stay grounded.
• Stress from tank mates: If you have other fish or axolotls in the tank, your floating axolotl might be trying to avoid confrontation.

How to Identify the Cause

Figuring out why your axolotl is floating starts with careful observation. Watch their behavior, check your tank’s conditions, and examine their physical appearance. Pay attention to these key areas:

Monitor Their Behavior

Does your axolotl float all the time or just occasionally? If they’re floating but still eating and moving normally, it’s probably not an emergency. But if they seem distressed or can’t swim down, it’s time to investigate further.

• Frequent surfacing: This may suggest they’re gulping air.
• Erratic swimming: Struggling to stay upright or sinking suddenly points to a buoyancy problem.
• Resting at the surface: If they seem tired, check for water quality or illness.

Check Water Conditions

Testing your water should always be your first step. A water testing kit is essential for axolotl owners. Measure ammonia, nitrites, nitrates, pH, and temperature. Make adjustments immediately if you notice anything off.

• Ammonia or nitrite levels: Should always be at 0 ppm.
• Nitrates: Should stay below 20 ppm.
• Temperature: Keep it stable in the 60–68°F range to prevent stress.

Inspect Their Body

Look closely at your axolotl. Signs like swelling, redness, or a distended belly can indicate bloating, impaction, or infection. Healthy axolotls have smooth skin, a relaxed posture, and a good appetite.

Adult axolotls measure between 20 to 30 cm (approximately 8 to 12 inches) in length.

How to Help a Floating Axolotl

Once you’ve identified the problem, it’s time to help your axolotl get back to normal. The solutions depend on the cause, so take a step-by-step approach.

Adjust Feeding Habits

If overfeeding or impaction is the problem, change how and what you’re feeding your axolotl.

• Feed smaller portions: Give food in small amounts to avoid bloating. A good rule is to feed them as much as they can eat in 1–2 minutes.
• Switch to safer substrates: Use fine sand or bare-bottom tanks instead of gravel to prevent accidental ingestion.
• Provide high-quality food: Offer a variety of foods, like earthworms, bloodworms, and axolotl pellets. Avoid fatty or low-nutrient options.

Improve Water Quality

Poor water conditions can be fixed with consistent maintenance and adjustments.

• Do frequent water changes: Replace 20–25% of the tank water weekly to keep it clean.
• Use a reliable filter: Make sure your filter is working efficiently but isn’t creating too much flow, as axolotls prefer calm water.
• Monitor temperature daily: Use a thermometer to keep the tank within the ideal range. Add a fan or chiller if needed.

Treat Health Issues

If you suspect illness, treating your axolotl quickly is crucial. Quarantine them in a separate tank if necessary and consult a vet for advice.

• Salt baths: These can help with fungal infections. Dissolve aquarium salt in dechlorinated water and soak your axolotl for 10–15 minutes.
• Medication: Infections may require antibiotics, which should only be used under professional guidance.
• Avoid stress: Limit handling and keep the environment calm while they recover.

Help with Buoyancy Problems

For axolotls struggling with buoyancy, some extra care might be needed.

• Gently burp them: If you suspect air-swallowing, gently guide your axolotl to the surface and let them release the air.
• Lower water levels: Reducing the tank depth temporarily makes it easier for them to rest.
• Provide resting spots: Add soft plants or decorations where they can anchor themselves.

Prevent Floating Problems

Prevention is always better than dealing with a stressed axolotl. A well-maintained tank and healthy routine keep floating issues to a minimum.

Maintain a Stable Tank

A stable environment is essential for axolotls to thrive.

• Cycle your tank properly: Make sure your tank is fully cycled before adding an axolotl. This prevents ammonia spikes.
• Use quality equipment: Invest in a good filter, heater, and testing kit to keep your tank in top shape.
• Avoid sudden changes: Keep water conditions as consistent as possible to reduce stress.

Feed Wisely

Feeding the right amount and type of food prevents bloating and impaction.

• Stick to a schedule: Feed juvenile axolotls daily and adults every 2–3 days.
• Use appropriate portions: A portion about the size of their head is a good guideline.
• Rotate foods: Variety ensures they get all the nutrients they need.

Keep an Eye on Behavior

Stay alert to changes in your axolotl’s activity, appetite, or appearance. Small problems are easier to fix when caught early.

• Regular checkups: Watch for changes in floating, swimming, or resting behavior.
• Clean the tank regularly: A clean environment reduces the risk of infections or stress.
• Be gentle with handling: Limit interactions to minimize stress.

Your Axolotl’s Comfort Comes First

Floating can be concerning, but it’s often manageable with the right care. By keeping an eye on your axolotl’s behavior and maintaining a healthy tank, you can prevent floating issues and address them quickly if they happen. A happy axolotl is a grounded axolotl, so prioritize their comfort and well-being.

When in doubt, always consult an expert or vet who specializes in aquatic animals. They’ll help you figure out what’s best for your little companion. Keep your tank clean, your feeding routine consistent, and your axolotl will reward you with its quirky, adorable personality for years to come.
