When I first decided to keep a snake, I thought it would be easy.
Buy a tank, toss in some wood chips, and drop the snake in.
Simple, right?
Wrong.
A few weeks in, my little corn snake looked stressed, wasn’t eating, and spent all day hiding under the water dish. I knew I had to fix my setup—but where did I go wrong?
If you’re reading this, you’re probably wondering the same thing:
“How do I set up a snake tank properly?”
Let me walk you through everything I learned the hard way, step by step—so your snake doesn’t have to go through what mine did.
Step 1: Choosing the Right Enclosure
Q: What size tank do I need for a snake?
Most beginners underestimate this part. Snakes don’t need a massive space, but too small of an enclosure can stress them out.
Here’s a general rule:
- Baby corn or king snakes: Start with a 20-gallon tank (30x12x12 inches).
- Adult snakes: Around 40 gallons or more, depending on the species.
- Ball pythons: Minimum of 36x18x12 inches for adults.
The key is to give your snake enough room to stretch, move, and hide comfortably.
When I upgraded my tank from 20 gallons to 40, I noticed my snake instantly became more active and relaxed. It was like watching someone finally get a good night’s sleep after weeks of discomfort.
Step 2: The Perfect Temperature and Humidity
Q: Do snakes need heat lamps or heat mats?
Yes! Snakes are cold-blooded, which means they rely on external heat sources. Without proper warmth, they can’t digest food properly or stay active.
Here’s what works:
- Under-tank heating pad: Perfect for maintaining belly warmth.
- Heat lamp: Provides a basking spot above.
- Thermostat: Absolutely essential to prevent overheating.
For most snakes:
- Warm side: 85–90°F (29–32°C)
- Cool side: 75–80°F (24–27°C)
I once made the rookie mistake of placing the heat mat directly under the entire tank. My snake had nowhere cool to escape, and it caused stress.
Always create a temperature gradient—warm on one side, cool on the other—so the snake can regulate its body temperature naturally.
Q: What humidity should I keep for my snake?
It depends on the species:
- Corn snakes: 40–60%
- Ball pythons: 50–70%
- Boa constrictors: Around 60–75%
Use a digital hygrometer and spray the enclosure lightly if it’s too dry. I found placing the water bowl near the warm side helps raise humidity too.
Step 3: Substrate and Decor — Making It Feel Like Home
Q: What should I use for the bottom of the snake tank?
Avoid sand or cedar shavings—they can cause health issues.
Best options:
- Aspen bedding (great for burrowing)
- Reptile bark
- Paper towels (for quarantine or cleaning simplicity)
- Coconut fiber (good for humidity)
I personally love aspen because it’s soft, easy to clean, and my snake loves tunneling through it.
Q: Do snakes need decorations?
Yes! Snakes may not care about pretty decor, but they love hiding spots. It helps them feel safe and secure.
Add:
- At least two hides (one on the warm side, one on the cool)
- Branches or logs (especially for climbing species)
- Water bowl big enough for soaking
- Fake plants or leaves for coverage
When I added an extra hide on the cool side, my snake started exploring more instead of curling up all day. A stressed snake becomes a confident one when it feels secure.
Step 4: Lighting and Day/Night Cycle
Q: Do snakes need UVB lighting?
Most snakes don’t require UVB like lizards do, but moderate UV exposure can be beneficial for activity and natural behavior.
However, always maintain a day/night cycle—around 12 hours of light and 12 hours of darkness.
A simple timer works wonders here.
When I started turning off the lights at night, my snake’s feeding and movement improved dramatically. It’s easy to forget reptiles have a rhythm, too.
Step 5: Feeding and Hydration
Q: What should I feed my snake and how often?
Feed appropriately sized prey—usually mice or rats no wider than the snake’s thickest part.
- Baby snakes: every 5–7 days
- Adults: every 10–14 days
Pro tip: Always thaw frozen food fully before feeding, and never leave live prey unattended—it can harm your snake.
My first feeding was a disaster. I offered a mouse that was too big, and my snake refused it for days. After downsizing, feeding became smooth and predictable.
Always keep fresh water available. Some snakes even soak in their bowl before shedding—it helps loosen the skin.
Step 6: Cleaning and Maintenance
Q: How often should I clean a snake tank?
Spot clean daily (remove waste, replace dirty substrate areas).
Do a full clean every 3–4 weeks:
- Remove the snake to a temporary box.
- Wash decor and tank with reptile-safe disinfectant.
- Dry thoroughly before resetting.
Keeping things clean prevents mites, odors, and stress.
Step 7: Common Mistakes to Avoid
New owners often ask:
Why is my snake not eating or hiding all the time?
Common reasons:
- Wrong temperature or humidity
- Too large or open of an enclosure
- No hiding spots
- Handling too soon after feeding or shedding
I learned this the hard way. When I stopped handling my snake for a week after a bad shed, she bounced back beautifully.
Final Thoughts: Making It a Partnership, Not a Project
Setting up a snake tank isn’t just about equipment—it’s about creating an environment that mimics nature. Once you get it right, you’ll notice your snake’s personality shine through.
There’s no better feeling than seeing your snake explore confidently, shed perfectly, and eat with ease—all signs of a healthy, happy reptile.
So if you’re just starting out, take it slow.
Ask questions, read, adjust, and learn.
Your first setup might not be perfect, but every small fix makes a huge difference.

Pro Tip:
If you ever feel lost, remember this rule:
If you wouldn’t live in it, your snake shouldn’t either.
Your snake setup isn’t just a cage—it’s a little world you create for your new friend. Make it safe, warm, and calm—and you’ll be rewarded with a long, healthy companion.
