Leopard geckos are amazing pets! They are small, friendly, and easy to care for. But one of the most important things you need to choose for your gecko is the substrate—the material that goes on the bottom of their tank. The right substrate keeps your gecko safe and happy. Let’s learn about the best options!
Why Good Substrate Matters
Substrate is not just “floor covering” for your gecko. It can affect their health in big ways:
- Stomach Blockage Risk: If your gecko eats substrate by accident, it can get stuck in their stomach. This is called impaction and can make them very sick.
- Skin Infections: Wet or dirty substrate can grow germs that hurt your gecko’s skin.
- Breathing Problems: Dusty substrate can make it hard for your gecko to breathe.
The best substrate is safe, easy to clean, and helps your gecko act like they would in the wild.
Best Substrate by Age
Baby Leopard Geckos (0-6 Months Old)
Baby geckos are small and curious. They might eat substrate by mistake, so avoid loose materials like sand or soil. The safest options are:
- Paper Towels
- Very safe (no risk of blockage)
- Super easy to clean (change every 2-3 days)
- Cheap and easy to find at any store
- Ceramic or Slate Tiles
- Safe (geckos can’t eat it)
- Easy to clean with soap and water
- Helps keep their nails short
Reddit reptile owners and vets agree: paper towels are the best for babies!
Adult Leopard Geckos (6 Months and Older)
Adult geckos are bigger and smarter about what they eat. They also love to dig and burrow. Good options include:
- DIY Mix (70% Topsoil + 30% Play Sand)
- Mix 7 parts organic topsoil (no fertilizer) with 3 parts play sand
- Bake in the oven at 250°F for 30 minutes to kill germs
- Let it cool before using in the tank
- Perfect for digging and natural behavior
- Bioactive Substrates
- Products like The Bio Dude Terra Sahara or Habistat Leopard Gecko Bedding
- These are pre-mixed and safe for adults
- Help clean waste naturally with tiny bugs called “springtails”
- Ceramic Tiles
- Still a great safe option for adults too!
