Pacman frogs can get rather large - females up to 7 inches diameter! Though they can be inactive day-to-day, they explore and move at night when provided enriching spaces. Larger, well-decorated enclosures encourage natural activity patterns and burrowing behavior. These frogs are cannibalistic and MUST be housed alone.
SOLITARY SPECIES ONLY - Pacman frogs are cannibalistic. Never house two frogs together under any circumstances, regardless of size or sex.
Why Enclosure Size Matters
A 10 gallon tank is NOT appropriate housing for adult frogs of either sex. Here's why:
- Unable to establish proper thermal gradient (warm to cool side)
- Insufficient floor space for exploration and burrow changes
- Height limitations make heating/lighting difficult
- No room for enrichment (multiple hides, plants, decorations)
- Females can grow to 7 inches - physically cramped in 10 gallon
- Stress from inadequate space suppresses immune system
Minimum Enclosure Sizes by Sex
Pacman frogs differ greatly in size between males and females, so minimum enclosure sizes differ. Make sure you properly sex your frog before committing to the smaller male minimum.
Minimum Height: All enclosures require minimum 12 inches of height, but 18+ inches makes heating and lighting much easier to manage.
Juvenile Pacman Frogs (Unsexed)
Minimum Size: 20°10°12" (50°25°30cm) or 200 sq in floor space
Breeders and pet stores sell frogs as young as quarter-sized. Baby frogs at this age have not been tested for growth, food response, and health. Smaller enclosures help monitor health during this vulnerable time. Upgrade to adult enclosure once 6-7 months old and able to be sexed.
Example Enclosures:
- 10 gallon aquarium (20°10°12")
- Exo Terra Small Low (18°18°12")
- Exo Terra Small Wide (18°18°18")
- Zoo Med 10 Gallon ReptiHabitat (20°10°12")
- Zoo Med Natural Terrarium NT-3 (18°18°12")
- Zilla 10 Gallon Critter Cage (20°10°12")
- Zilla 15 Gallon Critter Cage (24°12°12")
- Zilla QuickBuild Terrarium (20°12°10")
- Modified plastic bins of appropriate size (check interior dimensions)
UPGRADE REQUIRED - Juveniles must be moved to adult-sized enclosure at 6-7 months old. Keeping adult frogs in 10 gallon tanks causes chronic stress and health issues.
Male Pacman Frogs
Minimum Size: 30°12°12" (75°30°30cm) or 360 sq in floor space (20 gallon long equivalent)
Males grow to 3-4 inches diameter. Larger enclosures are always welcome and encouraged!
Example Enclosures:
- Exo Terra Medium Low (24°18°12")
- Exo Terra Medium Wide (24°18°18")
- Zoo Med 25 Gallon Naturalistic Terrarium (30°12°16")
- Zilla 20 Long Critter Cage (30°12°12")
- Zilla 20 Long Deluxe Critter Cage (30°12°12")
- Zilla Front Opening Enclosure (30°12°16")
- Zilla QuickBuild Terrarium (30°12°12")
- Modified plastic bins of appropriate size (check interior dimensions)
Female Pacman Frogs
Minimum Size: 36°18°18" (90°45°45cm) or 648 sq in floor space (40 gallon breeder equivalent)
Females grow to 5-7 inches diameter depending on species. They need significantly more space than males.

Enclosure Type Selection
Three main enclosure types work for Pacman frogs. Choose based on your humidity needs, budget, and aesthetic preferences:
Glass Terrariums
Best for: High humidity species (C. cornuta, C. aurita), budget-conscious keepers, those wanting easy viewing
Pros:
- Excellent humidity retention
- Clear viewing on all sides
- Readily available at pet stores
- Affordable (especially used aquariums)
- Heavy/stable (won't tip easily)
Cons:
- Screen tops allow heat/humidity escape
- Heavier to move and clean
- Can crack if dropped
- Top-opening only (can stress frog during maintenance)
Tips: Cover 50-75% of screen top with HVAC tape, foil, or acrylic to retain humidity on cool side. Keep warm side open for heat lamp.
PVC Enclosures
Best for: Serious keepers, multiple frogs in different enclosures, those wanting front-opening access
Pros:
- BEST humidity and heat retention
- Front-opening doors (less stressful maintenance)
- Lightweight compared to glass
- Very durable (won't crack)
- Professional appearance
- Can have integrated drainage for bioactive
Cons:
- Most expensive option ($150-400+)
- Limited viewing (front only typically)
- Fewer size options than glass
- Shipping costs can be high
- May need to order online
Recommended brands: Dubia.com, Zen Habitats, Custom Cages
Screen Enclosures
Best for: Temporary housing, very warm/humid rooms, dry climates with misting systems
Pros:
- Excellent ventilation
- Lightweight
- Affordable
- Easy to clean
Cons:
- VERY difficult to maintain humidity
- Not recommended for most Pacman frog setups
- Requires frequent misting
- Heat escapes rapidly
- Deep substrate can be difficult to manage
Screen enclosures are generally NOT recommended for Pacman frogs unless you live in a naturally humid environment (Florida, Hawaii, etc.) or have automated misting systems.
Modified Bin Enclosures
Plastic storage bins can be used for quarantine, grow-out enclosures, or transportation. They are NOT suitable as permanent housing for adult frogs.
When to use bins:
- Quarantine new frogs (30 days minimum)
- Temporary housing during enclosure cleaning
- Transporting frogs to vet appointments
- Grow-out enclosures for juveniles
- Emergency backup housing
Required modifications:
- Cut out center of lid (leave 2-3 inch border)
- Replace cutout with 1/4 inch or smaller hardware cloth mesh
- Secure mesh with zip ties, screws, or strong adhesive
- Mesh allows ventilation and safe overhead heat use
- Smooth any sharp edges that could injure frog
CRITICAL: UVB cannot be used with plastic bin enclosures. UVB radiation reacts with plastic to create toxic chemicals and makes plastic brittle. Bins are UVB-incompatible even with mesh lid.
For bin modification questions, contact experienced keepers on r/pacmanfrogs subreddit.
Decorations and Enrichment
Pacman frogs need coverage and decorations for security and enrichment. Many frogs burrow under plants, wood pieces, and leaf litter rather than sitting exposed.
Hides and Coverage
While frogs burrow to hide, they still benefit from overhead coverage. Provide options on both warm and cool sides of enclosure.
Hide options:
- Cork bark slabs and rounds (natural, holds humidity)
- Commercial hides WITHOUT bottoms (must allow burrowing)
- Half log hides depressed into substrate
- Terra cotta pots (break off rim, bury edge)
- Live or fake plants with broad leaves
- Driftwood pieces and branches
Avoid hides with plastic bottoms - frogs cannot burrow under them, preventing natural behavior. Remove bottoms or use natural hides that rest on substrate.
Leaf Litter (Essential)
Leaf litter should be added on top of substrate. Benefits:
- Extra enrichment and hiding spots
- Frogs burrow under large leaf pieces
- Prevents substrate ingestion during feeding
- Provides habitat for cleanup crew in bioactive setups
- Natural appearance
- Helps maintain humidity
Best leaf types: Magnolia (large, durable), oak leaves, catappa/Indian almond leaves, commercial reptile leaf litter
Live and Artificial Plants
Live plants (best for bioactive):
- Pothos (hardy, humidity-loving, trailing vines)
- Ferns (Boston, maidenhair, bird's nest)
- Bromeliads (hold water, tropical appearance)
- Philodendrons (easy care, large leaves)
- Spider plants (tolerant, safe)
- Syngonium (arrow head plant)
Artificial plants:
- No maintenance required
- Won't be damaged by frog
- Provide instant coverage
- Choose reptile-safe materials (no sharp edges)
- Wash before use
Overhead Vines and Foliage
Breaking up overhead lighting is especially beneficial for albino frogs but enriching for all morphs:
- Provides shade zones under lamps
- Makes frogs feel more secure
- Mimics natural canopy coverage
- Allows frog to choose sun/shade preference
Decorative Items
- Branches and sticks (not for climbing, but enrichment)
- Cork rounds (create tunnels when partially buried)
- Stones and rocks (smooth edges only, not small enough to swallow)
- Background images (taped to outside of enclosure)
- Natural wood pieces
Water Dish Requirements
Some frogs use water dishes extensively, others rarely. Fresh clean water should be provided at all times regardless.
Water dish requirements:
- Frog must fit entire body in dish for soaking
- Water depth: Frog sits with body under water but NOT fully submerged
- Pacman frogs are poor swimmers (short legs, small feet, no webbing)
- Frog must be able to exit dish without assistance
- Smooth sides with gradual slope or steps
Dish placement:
- Place on cool side of enclosure (prevents rapid evaporation)
- Bury rim level with substrate (easy access)
- Keep away from heat lamp (maintains cooler water)
Water maintenance:
- Change water daily (frogs often defecate in dish)
- ALL water must be treated with reptile/amphibian dechlorinator
- Clean dish weekly with reptile-safe cleaner
- Rinse thoroughly before refilling
Water dish too deep = drowning risk. Pacman frogs are NOT strong swimmers and can drown in deep water. They should always be able to touch bottom and keep head above water.
Layout Planning
Thermal gradient setup:
- Heat lamp and UVB on one side (warm side)
- Keep opposite side empty of heat sources (cool side)
- Place warm-side hide under heat lamp
- Place cool-side hide away from heat
- Water dish on cool side
- Deep substrate throughout (4-6 inches adults)
Avoid these layout mistakes:
- Heat sources on both sides (no thermal gradient)
- Water dish directly under heat lamp (rapid evaporation)
- All hides clustered in one area (no temperature choice)
- Decorations too close to heat lamp (fire hazard)
- Shallow substrate (prevents burrowing)
Complete Setup Checklist
Before adding your frog:
- Enclosure minimum size met (20 gal males, 40 gal females)
- Substrate 4-6 inches deep (see substrate guide)
- Leaf litter on top of substrate
- Heat lamp on one side (see heating & lighting guide)
- UVB fixture installed (optional but recommended)
- Thermometer probes on warm and cool sides
- Hygrometer probes on warm and cool sides
- Water dish on cool side (treated water)
- Hide on warm side
- Hide on cool side
- Overhead foliage/vines (especially for albinos)
- Plants and decorations added
- Temperatures stable: warm 80-85°F, cool 70-75°F
- Humidity 65-85% (species dependent)
- Let enclosure stabilize 24-48 hours before adding frog
Maintenance Schedule
| Frequency | Task |
|---|---|
| Daily | Change water dish, spot clean visible waste, check temperatures/humidity |
| Weekly | Mist substrate if needed, clean water dish, check all equipment functioning |
| Bi-weekly | Replace leaf litter as it decomposes |
| Monthly | Deep clean decorations, check substrate moisture throughout depth |
| Every 2-3 months | Replace substrate (except bioactive), full enclosure cleaning |
Bioactive Enclosure Additions
For those pursuing bioactive setups, add these components:
- Drainage layer (1-2 inches LECA or hydroballs with screen barrier)
- Bioactive substrate mix (ABG Mix or Terra Firma)
- Cleanup crew (dwarf white or powder orange isopods + temperate springtails)
- Live plants (pothos, ferns, bromeliads)
- Increased leaf litter (food source for CUC)
- Reduced maintenance (no substrate changes, minimal spot cleaning)
Budget-Friendly Setup Tips
- Buy used aquariums (check Craigslist, Facebook Marketplace, local reptile groups)
- Use organic topsoil instead of pet store substrate ($2-5 vs $8-15)
- Collect natural decor (branches, stones) - bake at 200°F for 30 min to sterilize
- Use terra cotta pots as hides (break off rim, $1-3 each)
- Buy feeder insects in bulk online (much cheaper than pet stores)
- DIY background with foam and silicone
- Join local reptile groups for free/cheap supplies
Common Setup Mistakes
- Enclosure too small for sex (10 gallon for adults)
- No thermal gradient (heat sources everywhere or nowhere)
- Insufficient substrate depth (frog visible when burrowed)
- Using bin enclosures with UVB (toxic reaction)
- Hides with plastic bottoms (can't burrow)
- No leaf litter (missing enrichment)
- Water dish too deep (drowning risk)
- No cool side hide (can't escape heat)
- Decorations too sparse (chronic stress)
- Not treating water with dechlorinator
