Pacman Frog Care Guide

🐸 South American Pacman Frog Care

🏆 VITAL STATS & DIFFICULTY
Experience Level: Beginner
Max Size: 4–7 Inches (Females are larger)
Lifespan: 10–15 Years
🏗️ Enclosure & Terrestrial Space

Pacman Frogs are sedentary, ambush predators. They do not require massive enclosures but do need significant substrate depth for burrowing.

Minimum Enclosure Dimensions:

  • Juveniles: 10 Gallon Standard.
  • Adults: 20 Gallon Long (30" x 12" x 12").

A glass terrarium with a screen lid is standard. Avoid large heights as these frogs are not climbers and can injure themselves if they fall from decor.

⚠️ CANNIBALISM WARNING

Pacman Frogs are highly aggressive toward anything that fits in their mouth—including other frogs. They MUST be housed individually for life.

☀️ Low-Intensity UVB & Ferguson Zones

While amphibians were once thought not to need UV, modern research shows it greatly benefits their immune system and bone density.

Ferguson Zone Classification:

  • ★ Zone 1 (Pacman Frogs): Shade dwellers/Crepuscular. Target UVI range: 0.5 to 1.0.
  • Zone 2-4: Dangerously intense for amphibian skin.

UVB Requirements:

  • Type: T5 HO Linear Tube (ShadeDweller style).
  • Strength: 2.4% to 5% (Arcadia ShadeDweller).
  • Photoperiod: 10–12 hours daily.

📐 Amphibian Sensitivity

Amphibian skin is highly permeable. Ensure the UV bulb is placed over a screen to filter the intensity and provide plenty of deep shade (leaf litter/hides).

🌡️ Temperature & Tropical Humidity

Pacman Frogs require consistent warmth and high humidity to prevent "Aestivation" (a dormant state caused by dry conditions).

Requirement Specification
Warm Side Ambient 78°F - 82°F
Cool Side Ambient 72°F - 75°F
Humidity Level 70% - 80% (Constant)
NIGHT DROP 68°F - 72°F
CRITICAL UPPER LIMIT NEVER ABOVE 85°F
Pro Tip: Use a side-mounted heat mat with a thermostat. Never place heat mats under the tank for Pacman frogs, as they burrow down to get *cool*, and an under-tank heater will cook them.
🦗 Carnivorous Nutrition & Feeding

These frogs will eat almost anything. However, a varied diet is required to prevent obesity and liver disease.

Staple Feeders:

  • Nightcrawlers (Earthworms): The #1 best staple. High in calcium and easy to digest.
  • Dubia Roaches: Excellent protein source.
  • Hornworms: Great for hydration.
  • Silversides/Small Fish: Occasional treat (thiaminase-free).

Supplementation:

Dust food with Calcium (with D3) every other feeding for juveniles, once a week for adults. Use a multivitamin once every two weeks.

⚠️ WARNING: MOUSE FEEDING

While they can eat "pinky" mice, these should be rare treats (once a month). Excessive vertebrate prey causes fatty liver disease and corneal lipidosis (cloudy eyes).

🌿 Substrate & Hygroscopy

Substrate is the most critical part of a Pacman Frog setup. They must be able to bury themselves completely.

Recommended Options:

  • Coco Fiber (Eco Earth): Holds moisture perfectly and is soft for burrowing.
  • Bioactive Mix: Organic topsoil, coco fiber, and sphagnum moss.
  • Depth: At least 4–6 inches deep.
🚨 TOXIC WATER WARNING

Amphibians absorb everything through their skin. You MUST use a water conditioner (like Zoo Med ReptiSafe) to remove chlorine and chloramines from tap water, or use spring water. Distilled water is dangerous as it lacks minerals.

📝 Daily & Monthly Maintenance
Daily: Mist the enclosure to keep substrate damp (not soaking wet).
Daily: Change the water in their shallow soaking dish.
Weekly: "Turn" the substrate to prevent stagnant/sour spots.
Monthly: Complete substrate change (if not bioactive).

❓ Frequently Asked Questions (FAQ)
Can I handle my Pacman Frog?Handling should be extremely limited. Their skin is sensitive, and they have a very strong, painful bite. Always wear powder-free gloves if you must touch them.
Why is my frog not eating?Usually due to low temperatures or the frog entering aestivation. Ensure the tank is at least 78°F.
What is "Aestivation"?A "sleep" state where the frog develops a hard, dry skin cocoon to survive drought. If this happens, increase humidity and warmth immediately.
Is Red Leg Disease real?Yes. It is a bacterial infection (usually from dirty substrate) that causes redness on the belly/legs. It is often fatal without vet care.
How often should I feed an adult?Every 2-3 days. Juveniles should be fed daily.
Do they need a basking light?Generally no, ambient heat is better. High-intensity basking lights can dry out their skin too quickly.
Why is my frog burrowed and not coming up?This is normal behavior! They spend 90% of their time buried with only their eyes showing.
Can they eat goldfish?No. Goldfish contain thiaminase, which blocks Vitamin B1 absorption and leads to neurological death.
Are they poisonous?No, Pacman frogs do not produce toxins that are harmful to humans, unlike Dart frogs.
What is "Tox Out"?When a frog absorbs its own waste through its skin in a dirty tank. Symptoms include spindly legs and seizures.
Should I provide a hide?Yes, though they "hide" by burrowing, leaf litter or a cave provides extra security.
Why are they called Pacman frogs?Because of their round shape and enormous mouths, which make up nearly half of their body.
Can they drown?Yes. They are poor swimmers. Their water dish should be very shallow (only up to their chin).
Do they croak?Males will occasionally croak or "chirp," especially at night or when it rains.
What color morphs exist?Many! Including Strawberry, Albino, Green, and "Fantasy" (which is a hybrid species).
