🐸 Pacman Frog Tank Size Guide by Age

Find the Right Enclosure for Every Stage of Growth

Pacman Frog Tank Size Guide by Age - At a Glance

Baby Pacman frogs need 1–5 gallon enclosures, juveniles do well in 10 gallons, and adults thrive in 15–20 gallon tanks. A too-large tank can stress young frogs, while too small a tank limits movement, humidity control, and enrichment. Learn the best size for every stage below.


Getting your Pacman frog’s tank size right is one of the most important decisions for their health and comfort. These frogs aren’t very active, but they still need space to burrow, soak, and feed comfortably. And because they grow quickly, the right tank size changes over time.

In this guide, you’ll learn:

  • Recommended tank sizes by age and growth stage

  • Why “bigger isn’t always better” for young frogs

  • Setup tips for each enclosure size

  • Common tank size mistakes to avoid

Baby Pacman Frogs (0–6 Months)

Recommended Tank Size: 1 to 5 gallons

Baby frogs are tiny—often less than 1 inch long. A large tank can make feeding difficult and stress them out.

Setup Tips:

  • Use a small Kritter Keeper or shoebox-style tub

  • Maintain humidity with a sealed lid and daily misting

  • Shallow water dish and loose coconut fiber substrate

  • Avoid deep tanks or glass aquariums that are hard to control

Juvenile Pacman Frogs (6–12 Months)

Recommended Tank Size: 10 gallons (minimum)

Juveniles begin to grow rapidly and will benefit from more floor space for burrowing and movement.

Setup Tips:

  • Use a standard 10-gallon glass tank or front-opening terrarium

  • Keep substrate at least 2 inches deep

  • Add hiding spots like cork bark, moss mounds, or leaves

  • Use a screen lid with 80–90% coverage to maintain humidity

Adult Pacman Frogs (1+ Year)


Recommended Tank Size: 15 to 20 gallons

Adult frogs can reach 4–7 inches depending on sex and species. They don’t need a tall tank but do need ample floor space.


Setup Tips:

  • Use a low-profile, wide terrarium

  • Add a larger water dish (they love soaking)

  • Maintain consistent humidity (60–80%) and temperature (75–85°F)

  • Consider a bioactive setup for long-term health and lower maintenance

Common Tank Size Mistakes

1. Too Big, Too Soon

Young frogs can struggle to find food or become stressed in large tanks. Start small and upgrade gradually.

 

2. Too Tall Instead of Wide

Pacman frogs are ground-dwelling. A wide tank is far better than a tall one.

 

3. No Room for Burrowing

Floor space is critical for digging and hunting. A cramped tank causes boredom and stress.

Pro Tip: Consider Future Growth

If you’d rather avoid buying multiple tanks, a 10-gallon starter setup with dividers can work for babies, then transition to a 15–20 gallon enclosure by adulthood.

Just remember:

  • Too large = hard to monitor babies

  • Too small = cramped, hard to control humidity for adults

 

Final Thoughts

Tank size matters more than you might think for Pacman frogs. From tiny hatchlings to chunky adults, choosing the right enclosure size by age ensures a healthy, stress-free life. Stick with low, wide enclosures and adjust as your frog grows for the perfect long-term habitat.

FAQ: Pacman Frog Enclosure Sizes

Q: Can I keep a baby Pacman frog in a 10-gallon tank?
A: Yes, but only with plenty of hiding spots and shallow feeding areas to prevent stress or difficulty locating prey.

Q: Should I upgrade the tank as my frog grows?
A: Yes. Expect to upgrade from a small bin to a 10-gallon, then eventually to 15–20 gallons as your frog matures.

Q: Do Pacman frogs need vertical climbing space?
A: No. They are terrestrial burrowers and prefer horizontal space
