Axolotls are weird, slow, and oddly lovable — but they’re not low-effort. They need the right setup to stay healthy long-term. Here’s what you actually need to keep an axolotl the right way, without wasting money on gimmicks.
1. A 20-Gallon Long Tank
Axolotls aren’t swimmers — they’re bottom-walkers. A 20-gallon long tank gives them floor space to move and grow.
Recommended:
Lifegard Aquatics 20 Gallon Rimless Clear Glass Aquarium
2. A Sponge Filter or Gentle HOB Filter
Strong flow stresses axolotls out. Sponge filters are quiet, oxygenate the water, and support biological filtration — perfect for these sensitive pets.
Option 1 – Sponge Filter:
Hygger Double Sponge Filter
Option 2 – Low-Flow HOB:
AquaClear 50 Power Filter (can be baffled down)
3. Cold, Clean Water
No heater needed — axolotls prefer 16–18°C (60–65°F). Use a thermometer and test kit to keep ammonia, nitrite, and nitrate levels safe.
Essentials:
TDS Water Test Kit
Stick-On Thermometer Strip
4. Bare Bottom or Fine Sand Substrate
Gravel is a choking hazard. Axolotls eat by sucking, and they can accidentally swallow stones. Go bare-bottom or use fine aquarium sand only.
Safe substrate:
CaribSea Super Naturals Sand
5. Hides + Decor
Axolotls like to hide and chill. PVC pipe, smooth caves, or low rocks work great — just avoid anything sharp or brightly lit.

6. Axolotl-Safe Food
They’re carnivores. Feed earthworms, frozen bloodworms, or sinking high-protein pellets.
Suggested pellets:
Zoo Med Axolotl Food
7. Water Conditioner
Use a dechlorinator with every water change — untreated tap water will damage their gills and skin.
Reliable option:
Seachem Prime Water Conditioner
Final Tip
Axolotls don’t complain. They won’t swim up and tell you when something’s wrong — they’ll just get sick. That’s why clean water, soft flow, and proper setup matter more than most people think. Get it right early, and your axolotl can live 10+ years with minimal stress.
