Frequently Asked Questions
Beginner Questions
What is an axolotl?
An axolotl is a type of aquatic salamander native to lakes in Mexico. Unlike most amphibians, they remain in their larval stage throughout their lives and never undergo metamorphosis.
Are axolotls fish or amphibians?
Axolotls are amphibians, but they are unique because they stay in their aquatic, juvenile form instead of transitioning to land like other salamanders.
How long do axolotls live?
In captivity, axolotls can live between 10 to 15 years with proper care. In the wild, their lifespan is often shorter due to environmental threats.
How big do axolotls get?
Axolotls typically grow to be 9 to 12 inches (23 to 30 cm) long when fully mature.
Do axolotls make good pets for beginners?
Yes! Axolotls are relatively low-maintenance compared to some exotic pets. However, they do require specific water conditions and tank setups, so beginners should be prepared to learn about proper care.
Can I hold my axolotl?
No, axolotls should not be handled unless absolutely necessary. Their skin is delicate and covered in a protective slime coat that can be damaged by touching.
Do axolotls have teeth?
Yes, but they are small and not used for biting. Instead, axolotls use suction to swallow their food whole.
Why do axolotls always look like they’re smiling?
Axolotls have a natural upward curve to their mouths, which gives them a permanent “smiling” expression. It’s just part of their unique look!
Can axolotls regrow their limbs?
Yes! Axolotls are famous for their ability to regenerate limbs, gills, parts of their heart, and even parts of their brain.
What colors do axolotls come in?
Axolotls come in a variety of colors, including wild type (dark with speckles), leucistic (pale pink with red gills), golden albino, melanoid (solid black), and more.
Are axolotls endangered?
Yes, wild axolotls are critically endangered due to habitat destruction and pollution in their native waters of Mexico. However, they are widely bred in captivity for pets and research.
Where do axolotls come from?
Axolotls are native to Lake Xochimilco and formerly Lake Chalco in Mexico. These lakes are the only natural habitats where wild axolotls can be found.
Advanced Questions
Can axolotls regenerate lost body parts?
Yes! Axolotls have an incredible ability to regenerate limbs, tails, and even parts of their organs. However, the process takes several weeks, and it's crucial to maintain clean water and minimize stress during healing.
How can I tell if my axolotl is male or female?
Males typically have a more swollen cloaca (the opening near the base of their tail), while females have a rounder body shape, especially when carrying eggs. These differences become more noticeable once they reach maturity (around 12-18 months).
Do axolotls need a seasonal temperature change to breed?
In the wild, axolotls breed during cooler seasons. Some breeders mimic this by gradually lowering the water temperature and adjusting light cycles, but it's not necessary unless you plan to breed them.
Can I keep multiple axolotls together?
Yes, but with caution. Axolotls of similar size can be housed together, but younger ones may nip at each other. Provide plenty of hiding spots and monitor for aggression or injury.
What are the signs of stress in an axolotl?
Common signs include gill curling, frequent floating, lack of appetite, or excessive hiding. Poor water quality, high temperatures, and excessive handling are common stressors.
Do axolotls require UVB lighting?
No, axolotls do not need UVB light, and too much exposure can cause stress. If using a light for plant growth, ensure your axolotl has shaded areas to rest.
Can axolotls get sick?
Yes, they are susceptible to infections, fungus, and impaction. Regular water changes, proper diet, and monitoring their behavior help prevent illness.
What is impaction, and how do I prevent it?
Impaction occurs when an axolotl swallows something it cannot digest, like gravel. Using fine sand or a bare-bottom tank prevents this issue.
Do axolotls need live food, or can they eat pellets only?
While high-quality pellets provide balanced nutrition, occasional live or frozen foods like earthworms and bloodworms offer enrichment and variety.
Why is my axolotl floating at the surface?
Floating can indicate gas buildup, swallowing air, or stress. If persistent, check water parameters and diet, and ensure they’re not constipated.
Can I use aquarium salt for my axolotl?
Only for medical treatments, like mild salt baths for fungus. Regular tank water should remain salt-free.
How do I cycle a tank for axolotls?
Cycling establishes beneficial bacteria that process waste. This usually takes 4-6 weeks. Use a water test kit to monitor ammonia, nitrites, and nitrates.
Why does my axolotl have red veins on its skin?
This can be normal if they’re active, but it may also signal stress or poor water conditions. Test your water and ensure the temperature is in a safe range.
Can axolotls live with fish or other aquatic animals?
It’s risky. Many fish will nip at their gills, and axolotls may eat smaller tankmates. If keeping them with anything, ensure it’s non-aggressive and can tolerate cool water.
What is the lifespan of an axolotl?
With proper care, axolotls can live 10-15 years, though some have been known to reach 20 years in captivity.
Tank Setup Questions
What is the minimum tank size for an axolotl?
A single axolotl needs at least a 20-gallon tank. Larger tanks provide better water stability and more space to explore.
Do I need a filter for my axolotl's tank?
Yes, a filter helps maintain water quality, but it must have gentle flow, as axolotls prefer still water.
What kind of substrate is safest for axolotls?
Bare-bottom tanks or fine sand are best. Avoid gravel, as axolotls may swallow it and suffer from impaction.
How cold should the water be for an axolotl?
The ideal temperature is 60-68°F (16-20°C). Water above 74°F (23°C) can cause stress and illness.
How do I maintain stable water parameters?
Perform regular water changes (20-30% weekly), test water frequently, and use a filter suitable for a low-flow environment.
What kind of hiding spots do axolotls need?
Axolotls appreciate caves, PVC pipes, or plants where they can rest and feel secure.
Can I use tap water in my axolotl's tank?
Yes, but always dechlorinate it first using a water conditioner.
How much lighting should an axolotl tank have?
Low lighting is best, as axolotls are sensitive to bright lights. If using lights, ensure they have shaded areas.
Do I need a heater for my axolotl?
No, axolotls thrive in cool water. If your home is too warm, use a fan or aquarium chiller instead.
How often should I clean my axolotl’s tank?
Spot-clean daily, remove uneaten food, and perform partial water changes weekly to maintain water quality.
Can I use live plants in an axolotl tank?
Yes! Choose hardy, low-light plants like anubias, java fern, or hornwort. Be mindful that axolotls may uproot them.
What should I do if my tank water gets cloudy?
Cloudy water is often due to bacterial blooms, overfeeding, or poor filtration. Ensure your tank is cycled, clean regularly, and avoid overfeeding.
