Pacman Frog Tank Setup: Small Footprint, One Big Rule About Substrate
On This Page▾
Pacman frogs are easy to house correctly, they're sedentary burrowers that don't need much space. The setup mistakes that cause problems for this species are specific and avoidable.
Enclosure Size
A 10 to 20 gallon terrarium works well for an adult, since this species spends the overwhelming majority of its time buried and motionless rather than moving around. Some specialist sources recommend a 24x18x18 inch enclosure as an ideal, but floor space matters far more than height here, this isn't a climbing species.
Always house one frog per enclosure. Pacman frogs are cannibalistic, and cohabitation isn't a workable option regardless of enclosure size.
Temperature
Daytime around 75 to 85°F, with a slightly warmer basking area near 83°F, dropping to 65 to 75°F at night. Provide heat with a side-mounted under-tank heat mat on a thermostat, or a low-wattage overhead bulb.
Never place a heat mat under the tank. Pacman frogs burrow to the substrate floor, and a mat positioned underneath risks burning a frog that's buried directly on top of it.
Humidity
60 to 80% is the target range, maintained through moisture-retentive substrate and daily misting. Let it drop back toward the lower end of that range between mistings rather than keeping the enclosure constantly waterlogged. A digital hygrometer takes the guesswork out of tracking this.
Substrate: The Detail That Matters Most
Use 3 to 4 inches of coco fiber or coco husk, kept moist enough for burrowing, with a light layer of sphagnum moss or leaf litter on top if you like.
Avoid gravel, rocks, bark chips, and charcoal entirely. These aren't just uncomfortable, they're genuinely abrasive to a Pacman frog's delicate skin and, more seriously, a real cause of this species' impaction risk, since it swallows whatever's nearby when it strikes at prey. Change the substrate every 2 to 3 months as waste builds up acidity, unless you're running a bioactive setup with a cleanup crew.
A Pacman frog's bite force has been compared, pound for pound, to some predatory dinosaurs relative to body size. It's a strange thing to picture from an animal that spends nearly all day sitting motionless under a few inches of coco fiber, waiting.
Lighting
No special lighting is required. A standard 12-hour light, 12-hour dark cycle using a basic LED works fine. Low-level UVB is optional and can support vitamin D synthesis, but isn't necessary if the diet is properly supplemented.
Furnishings
Keep it simple: a shallow, easy-to-clean water dish that won't risk drowning a burrowed frog, and a basic hide or some leaf litter for a sense of security. This species doesn't need, or use, elaborate decor.
This species is a notable contrast to the far more handleable White's Tree Frog, which tolerates being picked up.

❓ Frequently Asked Questions
What size enclosure does a Pacman frog need?
A 10 to 20 gallon terrarium suits an adult, since this frog spends nearly all its time buried and motionless. Some specialist sources call 24x18x18 inches ideal, but floor space beats height for a non-climber. One frog per enclosure, always: they are cannibalistic.
What temperature and humidity does a Pacman frog need?
Days at 75 to 85°F with a basking area near 83°F, nights at 65 to 75°F. Humidity sits between 60 and 80%, held there by moisture-retentive substrate and a daily misting.
What substrate is safe for a Pacman frog?
3 to 4 inches of coco fiber or coco husk, kept moist enough for burrowing. Avoid gravel, rocks, bark chips, and charcoal entirely, they're abrasive to a Pacman frog's delicate skin and a real cause of impaction, since this species swallows whatever's nearby when it strikes at prey.
Can you put a heat mat under a Pacman frog's tank?
No, never underneath. Pacman frogs burrow to the floor of the substrate, so a mat below the tank can burn a frog sitting right on top of it. Mount the mat on the side, on a thermostat, or use a low-wattage overhead bulb.
Does a Pacman frog need UVB lighting?
None required. A basic LED on a 12-hour light, 12-hour dark cycle is enough. Low-level UVB is optional, and it can support vitamin D synthesis, though a properly supplemented diet covers that.
