Axolotl Care Guide: Everything You Need to Know Before Buying
The Axolotl, often called the "Mexican Walking Fish," has taken the world by internet storm. Despite their fish-like appearance and gills, they are actually amphibians. They are unique, relatively easy to care for, and can live up to 15 years if provided with the right environment.
In this guide, we will walk you through the essential requirements for keeping a healthy and happy Axolotl.
1. The Perfect Tank Setup
Unlike many fish, Axolotls spend their entire lives underwater. However, they need space and specific conditions.
Tank Size: A minimum of 20 gallons for one adult Axolotl is required, but 30 gallons is highly recommended for better water stability.
Filtration: They prefer low-flow water. Use a Sponge Filter to prevent strong currents that can stress them out.
Substrate: Never use gravel, as they might swallow it. Use Fine Sand or leave the bottom bare (Bare Bottom).
2. Water Temperature and Quality
This is the most critical part of Axolotl care. They are cold-water creatures.
Ideal Temperature: Keep the water between 60°F and 68°F (15°C - 20°C). Anything above 72°F (22°C) can be fatal.
Cycling the Tank: You must cycle your tank for 4-8 weeks before adding an Axolotl to establish beneficial bacteria.
Water Changes: Perform a 20% water change every week to keep ammonia and nitrates at safe levels.
3. Feeding Your Axolotl
Axolotls are carnivores and have a very simple but specific diet.
Best Food: Nightcrawlers (Earthworms) are the best staple diet. They are nutritionally complete.
Secondary Options: Bloodworms (as treats) and high-quality sinking carnivore pellets.
Feeding Frequency: Adults should be fed every 2-3 days, while juveniles need food daily.
4. Why You Should Never Use Lighting
Axolotls do not have eyelids and are very sensitive to bright light.
Natural Light: Standard room light is usually enough.
Aquarium Lights: If you use them for plants, ensure there are plenty of hiding spots (caves or PVC pipes) where your Axolotl can escape the light.
5. Can Axolotls Have Tank Mates?
The short answer is: No.
Fish: Fish often nip at the Axolotl’s fluffy external gills.
Other Axolotls: They can be kept together if they are the same size, but young ones are known to be cannibalistic. It is safest to keep them alone.
