Signs of a Healthy Axolotl
Before learning about diseases, know what healthy looks like. A healthy axolotl has full, fluffy gills (pink to red), smooth skin free of white patches, a good appetite, calm movement on the bottom, and a body slightly wider than its head with no bloating.
Axolotls are hardy animals, but they can develop health issues when water conditions deteriorate or when they are stressed. Early detection and treatment are key to recovery.
Common Health Problems at a Glance
| Problem | Key Symptoms | Primary Cause |
|---|---|---|
| Fungal Infection | White cotton-like growths on gills/body | Poor water quality, injury |
| Ammonia Burns | Red skin patches, curled gills, lethargy | Uncycled tank, overfeeding |
| Floating | Cannot sink to the bottom | Swallowed air, constipation, infection |
| Gill Deterioration | Short, thin, or curled gills | Chronic poor water quality |
| Impaction | Bloating, food refusal, swelling | Ingesting gravel or oversized food |
| Stress | Curled gill tips, pale color, hiding | Bright lights, strong current, handling |

Treatments by Condition
Fungal Infection
Salt baths (2-3 tsp non-iodized salt per liter, 10-15 min) + improve water quality immediately. Methylene blue for severe cases.
Ammonia/Nitrite Burns
Immediate large water change (50-80%). Daily water changes until levels return to 0 ppm. Review filtration capacity.
Floating (Buoyancy Issues)
Shallow container with cool clean water. Fast for 2-3 days. Gentle belly massage. Fridging in severe cases.
Gill Deterioration
Optimize water parameters, lower temperature to 16-18°C. Gills can regrow over weeks with proper conditions.
Impaction
Fridging (4-8°C) to slow metabolism and pass the obstruction. Switch to bare bottom tank permanently.
Stress
Identify and remove the stressor. Provide more hides, dim lighting. Check water parameters.
The Fridging Method
Prevention Checklist
Prevention Beats Treatment
A properly maintained tank prevents 90% of health issues. If your axolotl gets sick, the first step is always to test water parameters. Most problems trace back to ammonia, nitrite, or temperature outside the safe range.
