Is It Time to Upgrade My 3 Feet 4 Inches Snake’s 20-Gallon Tank?


Dear VetBabble,

I recently measured my snake, and he’s about 3 feet 4 inches long. He’s currently living in a 20-gallon tank. I want to make sure he has everything he needs and is not feeling cramped. How do I know when it’s time to get him a larger tank? Do snakes require a lot of space, or is his current setup sufficient?

Understanding Your Snake’s Space Requirements

It’s great that you’re concerned about your slithery friend having enough space to live comfortably! Snakes are fascinating creatures, and providing proper care for them means ensuring they have suitable living conditions. When it comes to tank size, it’s essential to consider the specific needs of your snake species. Some snakes require more space, while others can live happily in smaller habitats.

In general, a 20-gallon tank is a suitable size for many snakes, especially if it’s set up properly with the necessary hiding spots, suitable substrate, and proper temperature control. However, if you want to cater to your specific snake’s needs, here are some helpful guidelines:

A general rule of thumb is that the enclosure’s length should be at least two-thirds of your snake’s length. For your 3-foot-4-inch long snake, a 20-gallon tank can be sufficient. However, if you want to provide more space for your snake to stretch out, explore or climb (depending on the species), you can consider upgrading to a larger tank.

Tank Setup and Accessories

A bigger tank does not always equate to a better environment for your snake. In addition to space, it’s crucial to provide the right setup and accessories for your snake’s comfort and well-being. Here are some additional factors you should consider when deciding on your snake’s habitat:

  • Substrate: Choose a substrate that is easy to clean and safe for your snake. You can use paper towels, butcher paper, or newspapers for a simple, low-cost option. Swapping these out regularly can help ensure a sanitary environment for your snake.
  • Hiding Spots: Snakes enjoy hiding and need a place where they feel safe to retreat and escape the light. Offering multiple hiding spots can help reduce stress and promote security for your pet. Options include commercial hides or homemade solutions like cardboard boxes and plant pots.
  • Climbing Opportunities: While not all snake species are avid climbers, providing branches or other climbing structures can make the enclosure more engaging for your snake and offers additional exercise opportunities.
  • Temperature and Humidity Control: Each snake species has specific temperature and humidity requirements. Ensure your enclosure has a warm side and a cool side, allowing your snake to regulate its body temperature. A digital hygrometer can help you monitor humidity levels.

Additional Care Tips for Different Exotic Pets

While your main concern may be providing the right space for your snake, it’s just as important to know how to care for other exotic pets if you have any or are considering expanding your menagerie. Check out these useful guides on VetBabble:

In conclusion, a 20-gallon tank can be adequate for your 3-feet-4-inch snake, as long as you provide a suitable environment with appropriate accessories. If you want to upgrade to a larger tank and can meet your snake’s needs, that’s great too! Regardless of your decision, it’s important to continue monitoring your snake’s behavior and well-being to ensure it remains a happy and healthy member of your family.
