You’ve just walked up to your axolotl’s tank, and there it is—your adorable little aquatic buddy, floating at the top like a balloon on a string. It’s not the usual playful hovering, though.
Something feels off, and now you’re worried. Don’t panic! Axolotl floating can happen for a few reasons, and most of the time, you can fix it with a few simple steps.
Let’s talk about what causes it, how to handle it, and how to make sure your axolotl stays happy and healthy.
Why Is My Axolotl Floating?

Floating is a common issue with axolotls, but it’s not always a reason to worry. It usually means there’s something affecting their buoyancy.
Floating can be alleviated by gently raising the axolotl out of the water for 5 to 10 seconds, helping them return to the bottom without extreme measures like refrigeration.
This could be harmless, like gulping too much air, or it might point to more serious concerns, like constipation or water quality issues. Understanding what’s causing the floating is the first step to fixing it.
Common Causes of Floating
Let’s break them down:
1. Swallowed Air
Sometimes, axolotls gulp air from the surface. While it’s cute to watch, this can make them float temporarily. Usually, they’ll release the air naturally, so this isn’t too concerning.
2. Constipation
A bloated belly from constipation can lead to floating. Axolotls can struggle to expel waste if their diet isn’t balanced or if they’ve eaten something they shouldn’t.
3. Water Quality Problems
Axolotls are sensitive to their environment. If the water conditions are poor—high ammonia levels, improper pH, or too much nitrate—it can stress your axolotl and affect its buoyancy.
4. Infections or Health Issues
Internal infections, gas buildup, or parasites might make your axolotl float. A floating axolotl with other signs like redness, lethargy, or a lack of appetite might need medical attention.
5. Incorrect Tank Setup
Sometimes, the problem is the setup itself. If your axolotl doesn’t have enough space or the water isn’t deep enough, it might struggle to stay comfortable.
The axolotl’s population density has drastically decreased from approximately 6,000 individuals per square kilometer in 1998 to only 35 individuals per square kilometer by 2015 due to habitat pollution and urbanization.
Steps to Prevent Your Axolotl from Floating
Now that you know the possible causes, let’s go over what you can do. Prevention is all about keeping your axolotl’s environment safe and their routine healthy.
Maintain Ideal Water Quality
Axolotls thrive in stable, clean water. Bad water conditions can stress them out, and stress is one of the main reasons axolotls have health problems.
- Test the water regularly. Use a water testing kit to check ammonia, nitrite, and nitrate levels. Ammonia and nitrite should always be at 0, while nitrates should stay under 20 ppm.
- Keep the pH between 6.5 and 7.5. Axolotls prefer slightly alkaline water.
- Change the water consistently. Replace 20-30% of the tank water weekly to keep it fresh and clean.
- Use a sponge filter. This helps maintain water quality without creating strong currents, which axolotls dislike.
Feed a Proper Diet
Axolotls need a varied diet to stay healthy. If they don’t get enough fiber or protein, they’re at risk of constipation.
- Offer high-quality food. Feed them pellets designed for axolotls, live earthworms, or frozen bloodworms.
- Avoid overfeeding. Adult axolotls should eat two to three times a week, while juveniles need daily feedings.
- Watch portion sizes. Too much food can lead to bloating and floating.
Provide the Right Tank Setup
A good tank setup can prevent floating and make your axolotl more comfortable.
Estimates indicate that there are now between 50 and 1,000 axolotls left in the wild, classified as critically endangered by the IUCN since 2006.
- Give them enough space. A 20-gallon tank is the minimum for one axolotl. Larger tanks allow them to move freely.
- Ensure proper water depth. At least 10-12 inches of water helps them regulate buoyancy naturally.
- Add hiding spots. Decorations like caves or PVC pipes provide a safe space for your axolotl to relax.
Handle Floating Issues Quickly
If your axolotl is already floating, you can help them get back to normal.
Temporary Solutions for Floating
- Adjust their position. Gently nudge your axolotl back into the water if they’re stuck at the top.
- Lower the water level. This can make it easier for them to reach the bottom while they recover.
- Let them rest. Avoid stressing your axolotl by keeping the tank quiet and free from sudden disturbances.
Address Constipation
If you suspect constipation, try these steps:
- Feed soft, easy-to-digest foods. Peeling and blanching a small piece of frozen pea can help ease digestion.
- Offer a fasting day. Skip feeding for a day or two to give their digestive system a break.
- Keep the water temperature stable. Higher temperatures can sometimes help with digestion but don’t exceed 72°F.
Seek Medical Help for Severe Issues
If floating doesn’t improve or your axolotl shows other signs of illness, consult a vet. Axolotl-savvy vets can diagnose problems like infections or gas buildup.
Long-Term Care Tips for a Healthy Axolotl
Preventing floating issues is easier when you focus on overall care. Here’s how to keep your axolotl healthy and happy:
Monitor Behavior Regularly
Axolotls have unique personalities, so you’ll notice when something’s off. If your usually active axolotl is suddenly floating or acting lethargic, take action quickly.
Avoid Common Stressors
Axolotls can get stressed from poor handling, loud noises, or overly bright lights. Stick to dim lighting, and avoid tapping on the tank or disturbing them unnecessarily.
Quarantine New Additions
If you’re adding tank mates or plants, quarantine them first. New items can introduce diseases or parasites to your axolotl’s tank.
Keep the Tank Cool
Axolotls prefer water temperatures between 60°F and 68°F. Higher temperatures can lead to stress and health problems. Use a fan or aquarium chiller to maintain the right temperature.
Use Proper Substrate
Avoid gravel, as axolotls might accidentally swallow it, leading to impaction. Sand or bare-bottom tanks are safer options.
Wrapping It All Up
Floating might seem scary at first, but it’s often something you can fix with a bit of care. Keep an eye on water quality, feed your axolotl a healthy diet, and make sure their tank setup suits their needs. When you pay attention to their health and environment, you’re helping your axolotl live a long, happy life.
If floating does happen, don’t stress. Follow the steps we’ve covered here, and you’ll likely see your axolotl bouncing back in no time. After all, your little aquatic friend relies on you to keep their world safe and stress-free. Stay consistent, and you’ll both enjoy the journey together.
