Your axolotl is more than just a pet—it’s a unique little companion that looks like it swam straight out of a fairy tale. One of their most enchanting features is their feathery, fluffy gills that wave gently underwater.
But sometimes, those gills can look a little less fluffy than you’d like.
Don’t worry! With the right care and attention, you can help your axolotl maintain those gorgeous, fluffy gills they’re known for.
Why Do Axolotl Gills Lose Their Fluffiness?

Axolotl gills might lose their fluff for a few reasons. Water quality, stress, diet, or illness can all play a role. Knowing the cause makes it easier to fix the issue. Let’s go over each one so you’ll know exactly what to look for.
A 2009 survey indicated that there are fewer than 1,200 axolotls remaining in the Xochimilco Lake complex, highlighting their critically endangered status.
Poor Water Quality
Your axolotl’s gills are highly sensitive to changes in their environment. Ammonia, nitrite, and nitrate levels that are too high can irritate their gills, causing them to shrink or lose their fluff. A tank that’s not cycled properly or has too many fluctuations in water conditions can cause this issue.
To prevent this:
- Test your water regularly using a reliable water test kit.
- Keep ammonia and nitrites at 0 ppm, and nitrates below 20 ppm.
- Perform weekly water changes, replacing 20–30% of the tank water.
Stress
Axolotls can get stressed easily, and stress directly affects their gills. Causes of stress include:
- Bright lights (axolotls prefer dim or no light).
- Fast water flow from filters.
- Tankmates that nip at their gills or disturb them.
To minimize stress:
- Use a gentle filter with an adjustable flow rate.
- Add hiding spots like aquatic plants, caves, or ornaments.
- Keep them in a calm, quiet environment.
Poor Diet
A healthy diet plays a huge role in maintaining those fluffy gills. Protein-rich foods like earthworms, blackworms, and high-quality pellets give your axolotl the nutrients they need to stay healthy. If they’re not getting enough nutrients, their gills might thin out.
Make sure to:
- Feed a varied diet to ensure balanced nutrition.
- Offer live or frozen foods that mimic their natural diet.
- Avoid overfeeding to prevent poor water quality from excess waste.
Illness or Parasites
Illnesses and parasites can cause axolotl gills to shrink or lose their fluff. Fungal infections or gill parasites are common culprits. Signs of illness include:
- Pale or white patches on the gills.
- Excessive scratching or rubbing against tank surfaces.
- Lethargy or reduced appetite.
During the breeding season, female axolotls can lay between 300 and 1,000 eggs, which they place on plants or rocks to protect them from predators.
If you notice these signs, consult an exotic pet vet for treatment.
Setting Up the Perfect Tank for Fluffy Gills
Creating the ideal tank environment is essential for keeping your axolotl’s gills full and fluffy. A well-maintained habitat mimics their natural conditions and keeps them healthy.
Tank Size and Setup
A spacious tank allows your axolotl to move around comfortably and helps keep the water conditions stable. For a single axolotl:
- Use at least a 20-gallon tank. Bigger is always better.
- Keep the tank water shallow enough for them to touch the bottom easily.
Add these to make the space inviting:
- Fine sand or a bare-bottom tank (avoid gravel—it can cause impaction).
- Live plants like java fern or anubias for shade and hiding spots.
- Smooth rocks and caves for resting.
Temperature and Lighting
Axolotls thrive in cool, dim environments. Keep the water temperature between 60–68°F. Warmer water can cause stress, leading to gill issues. Use a reliable aquarium thermometer to monitor temperature daily.
As for lighting:
- Keep the tank in a shaded area.
- Use low-intensity aquarium lights if needed, but only for short periods.
Axolotls can measure anywhere from 6 to 18 inches in length, with weights ranging between 2 to 8 ounces.
Filtration and Water Flow
Axolotls dislike strong water currents. Choose a filter with adjustable flow rates or use a sponge filter, which is gentle and perfect for their needs. If you notice their gills bending from water movement, reduce the flow.
The Role of Oxygen in Fluffy Gills
Oxygen levels directly affect axolotl gills. When oxygen levels are low, their gills may shrink as they work harder to breathe. You can boost oxygen in the tank by:
- Using an air stone or bubble wand to increase surface agitation.
- Adding live plants, which naturally produce oxygen during the day.
- Avoiding overcrowding, which depletes oxygen levels.
Grooming Your Axolotl’s Gills Naturally
You don’t need to touch your axolotl’s gills—they’re delicate and self-maintaining. But you can support their health by ensuring the right environment. Here’s how to give their gills a natural boost.
Use Indian Almond Leaves
Indian almond leaves are a favorite among aquarists. They release tannins, which help create a more natural, slightly acidic environment. These leaves have antibacterial properties, reducing stress and promoting healthy gill growth.
Simply:
- Place 1–2 leaves in your tank.
- Replace them every few weeks as they break down.
Offer a High-Protein Diet
Diet impacts every part of your axolotl’s health, including their gills. High-protein foods like:
- Earthworms (a staple option).
- Bloodworms or blackworms.
- Axolotl-specific pellets.
These foods support gill regeneration and overall health. Avoid feeding insects or feeder fish, as they may carry parasites.
Keep Stress at Bay
Axolotls love routine. Sudden changes, like rearranging the tank or moving them too often, can cause stress. Keep things consistent and avoid handling them unless necessary.
Spotting Warning Signs Early
Keeping an eye on your axolotl ensures you catch problems early. Watch for these signs that their gills might need extra care:
- Discoloration (pale or dark patches could mean illness or stress).
- Gills that appear to shrink or flatten.
- Excess mucus on their gills (a sign of poor water quality).
If you notice these signs, address the root cause quickly. Regular checks help you stay ahead of potential issues.
How Long Does It Take for Gills to Grow Back?
If your axolotl’s gills have shrunk, don’t worry—they can grow back with proper care. The time it takes depends on the cause. Environmental improvements like better water quality or reduced stress can show results in a few weeks. For more severe issues, like illness, it may take longer.
Focus on:
- Maintaining a clean, stable environment.
- Providing a nutrient-rich diet.
- Reducing any sources of stress.
Patience is key, but most axolotls bounce back beautifully when their needs are met.
Common Mistakes to Avoid
Sometimes, well-meaning owners make small mistakes that can affect gill health. Here’s what to avoid:
- Skipping water tests: You can’t see ammonia or nitrite levels, so test regularly.
- Using untreated tap water: Always use a water conditioner to remove chlorine and chloramines.
- Overfeeding: Excess food causes waste buildup and poor water quality.
- Ignoring tank size: Small tanks stress axolotls and make it harder to keep conditions stable.
Create a Gill-Friendly Routine
A simple, consistent routine helps you maintain your axolotl’s gills and overall health. Here’s an easy plan to follow:
1. Daily
- Check water temperature.
- Observe your axolotl for any signs of stress or illness.
2. Weekly
- Test water parameters.
- Perform a 20–30% water change.
3. Monthly
- Rinse the filter media with tank water.
- Replace any worn-out decorations or plants.
Keep Your Axolotl Happy and Healthy
Fluffy gills are a sign of a happy, healthy axolotl. By providing the right environment, a balanced diet, and regular care, you’ll help your little buddy thrive. They rely on you for everything, and with just a bit of effort, you’ll be rewarded with a pet that’s not only healthy but stunning to look at.
Take care of their needs, and those fluffy gills will be back in no time. Your axolotl will thank you with every graceful swim and adorable look!
