Why is My Axolotl Floating? Causes and Solutions for Floating Issues
Introduction: Should You Worry?
Seeing your axolotl floating helplessly at the water’s surface can be frightening. While sometimes it’s just a quirky behavior, other times it is a sign of stress or illness. Understanding why your axolotl is floating is the first step to ensuring their health and safety.
1. Air Bubbles (The “Gulping” Effect)
Axolotls have both gills and primitive lungs. Occasionally, they swim to the surface to take a gulp of air. If they swallow too much, the air gets trapped in their digestive tract, causing them to float like a balloon.
-
The Sign: The axolotl looks healthy but cannot stay at the bottom.
-
The Solution: Usually, they will eventually “burp” or pass the gas naturally.
2. Constipation or Impaction
If your axolotl hasn’t pooped in a while, gas can build up in the gut. This is often caused by eating food that is too large or accidentally swallowing gravel/substrate.
-
The Sign: Floating with the tail tilted upwards.
-
The Solution: Offer a “tea bath” or simply wait. Never use gravel in an axolotl tank; use fine sand or a bare bottom.
3. Poor Water Quality (Ammonia Spikes)
High levels of Ammonia or Nitrites can irritate an axolotl’s skin and gills, causing them to float due to stress or respiratory distress.
-
The Sign: Floating accompanied by curled gills or a curled tail.
-
The Solution: Test your water immediately using a liquid test kit. Perform a 30-50% water change if levels are high.
4. High Water Temperature
Axolotls are cold-water creatures. If the water gets above 22°C (72°F), it holds less oxygen, causing the axolotl to struggle and float near the surface where oxygen levels are slightly higher.
-
The Sign: The axolotl looks lethargic and the water feels warm to the touch.
5. Stress from Strong Filter Flow
Axolotls hate strong currents. If your filter is too powerful, the water movement can push them around, making it look like they are floating. This stresses them out significantly.
When is it an Emergency?
If your axolotl is floating sideways or upside down, or if they are trying desperately to swim down but keep popping back up for more than 24 hours, it’s time to consult an exotic vet or consider “Tubbing” them in shallow, cool water.
