Pac-Man Frog Care Guide

The Pac-Man Frog (Ceratophrys spp.) is one of the most popular and beginner-friendly amphibians in the hobby. Named for their enormous mouths and round, voracious appearance, these South American horned frogs are ambush predators that spend most of their time buried in substrate waiting for prey to walk by. They are low-maintenance, don't require large enclosures, and come in a stunning array of colors and morphs. If you want a frog that has personality and presence without demanding constant attention, the Pac-Man Frog is hard to beat.

At Ohio Pet Depot, we carry multiple Pac-Man Frog morphs including the Green Pac-Man Frog, Albino Pac-Man Frog, Chocolate Pac-Man Frog, Lemon Drop Patternless Pikachu Pac-Man Frog, and the Raspberry Pac-Man Frog. This guide covers everything you need to keep them healthy and thriving.

Enclosure Setup

Size

Pac-Man Frogs are sedentary and do not need large enclosures. A 10-gallon tank is sufficient for a juvenile; a 20-gallon is ideal for an adult female (the larger sex). Males can be kept comfortably in a 10-gallon their entire lives. Bigger is not always better — a very large enclosure makes it harder for the frog to find food and can cause stress.

Substrate

Substrate is critical — Pac-Man Frogs must be able to burrow and must stay moist at all times. Best options:

Maintain substrate depth of at least 3–4 inches so the frog can fully bury itself. Keep the substrate damp but not waterlogged — it should feel like a wrung-out sponge. Dry substrate causes dehydration and skin problems; standing water causes bacterial infections.

Water Dish

Provide a shallow water dish no deeper than the frog's chin when sitting. Pac-Man Frogs absorb water through their skin — they do not drink. The dish should be easy to enter and exit. Change the water daily — these frogs defecate in their water dish regularly.

Hides & Decor

Pac-Man Frogs don't need much decor — they will bury themselves in the substrate and use that as their hide. A simple cork bark flat or half-log on the surface gives them an option if they prefer to hide above ground. Keep decor minimal to make cleaning easier.

Temperature & Lighting

Temperature

Zone Temperature
Ambient (daytime) 75–82°F
Warm side (optional) 80–85°F
Nighttime low 65–72°F (can drop naturally)

Pac-Man Frogs are tolerant of a range of temperatures but do best in the mid-70s to low 80s. Temperatures above 85°F cause heat stress. If supplemental heat is needed, use a low-wattage Fluker's Ceramic Heat Emitter on a thermostat — never use an under-tank heater (UTH) directly under a Pac-Man Frog enclosure without a thermostat, as these frogs burrow into the substrate and can be burned by unregulated bottom heat.

UVB Lighting

UVB is not strictly required for Pac-Man Frogs but low-level UVB is beneficial for long-term health and vitamin D3 synthesis. A Zoo Med ReptiSun Compact Fluorescent UVB Bulb (5.0) on a 10–12 hour cycle is a good option. Keep the light source at least 12" from the frog's resting area. If not using UVB, ensure vitamin D3 is included in your supplement rotation.

Photoperiod

Maintain a 12-hour light / 12-hour dark cycle. Pac-Man Frogs are primarily nocturnal and most active after lights out.

Humidity

Target 60–80% humidity at all times. Pac-Man Frogs are highly susceptible to dehydration — a dry enclosure is one of the most common causes of illness and death in captive frogs.

  • Mist the enclosure once or twice daily to maintain humidity and keep the substrate damp
  • A tight-fitting screen lid with partial coverage (glass or plastic over part of the screen) helps retain humidity
  • A digital hygrometer is strongly recommended
  • If the frog forms a cocoon (a hardened layer of shed skin around its body), it is severely dehydrated — soak immediately in shallow, dechlorinated water and address husbandry

Diet & Feeding

Pac-Man Frogs are aggressive, indiscriminate carnivores. They will attempt to eat anything that moves and fits in their mouth — including your fingers. Feed with tongs or drop prey into the enclosure; never hand-feed directly.

Feeder Insects (Staples)

  • Banded Crickets — excellent staple; stimulates strong feeding response
  • Dubia Roaches — nutritionally superior staple; low odor, easy to keep
  • Nightcrawlers — outstanding protein source; highly accepted and great for variety
  • Red Worms — excellent for juveniles and smaller frogs
  • Superworms — great for larger adults; high in protein and fat
  • Mealworms — good variety feeder; offer in moderation due to chitin content

Treat Feeders (Occasional)

  • Hornworms — high moisture, great for hydration; offer occasionally
  • Wax Worms — high fat; use sparingly as a treat or appetite stimulant
  • Frozen Feeder Rats (pinky/fuzzy size) — appropriate for large adult females only; offer no more than once a month — too much rodent protein causes obesity and liver disease

Feeding Schedule

Age Frequency Prey Size
Juvenile (under 3 months) Daily or every other day Small crickets, red worms, small dubias
Sub-adult (3–6 months) Every 2–3 days Medium crickets, dubias, nightcrawlers
Adult (6+ months) Every 3–7 days Large crickets, dubias, nightcrawlers, superworms; occasional pinky for large females

Prey size rule: Offer prey no larger than the width of the frog's head. Pac-Man Frogs are notorious for attempting to eat prey that is too large, which can cause impaction or choking.

Overfeeding warning: Pac-Man Frogs have no "off switch" and will eat every time food is offered. Obesity is one of the most common health problems in captive Pac-Man Frogs. Stick to the feeding schedule above — a healthy adult frog should have a rounded but not bloated appearance.

Supplements

Dust all feeder insects with Fluker's Repta Calcium at every feeding for juveniles and every other feeding for adults. Use a multivitamin supplement (with vitamin D3 if not using UVB) once every 1–2 weeks. Gut-load crickets 24–48 hours before feeding with Fluker's Orange Cube Cricket Diet.

Handling & Temperament

Pac-Man Frogs are not a handling pet. They are display animals — fascinating to observe but not suited for regular interaction.

  • They will bite — Pac-Man Frogs have teeth (odontoid projections) and a powerful bite. Large adults can draw blood. Never put fingers near their mouth
  • Skin absorption risk: Frogs absorb chemicals through their skin. Always wash hands thoroughly before and after any contact. Never handle with lotions, soaps, or insect repellent on your hands
  • Minimize handling to reduce stress. If you must move the frog, use a damp glove or cup it from below
  • Stress in Pac-Man Frogs manifests as screaming (yes, they scream), puffing up, and biting — all signs to back off immediately

Health & Common Issues

Issue Signs Cause / Action
Dehydration / Cocoon formation Sunken eyes, hardened skin layer, lethargy Dry enclosure; soak immediately in shallow dechlorinated water; increase misting and substrate moisture
Obesity / Fatty liver disease Extremely bloated appearance, lethargy, loss of appetite Overfeeding or too many fatty prey items; reduce feeding frequency, eliminate rodents and waxworms
Impaction No defecation, distended abdomen, lethargy Ingested substrate or oversized prey; warm soak, gentle belly massage; vet visit if no improvement
Red Leg Syndrome Reddening of the legs and belly, lethargy, loss of appetite Bacterial infection from dirty water or substrate; full enclosure clean, water change; vet visit — antibiotics may be needed
Metabolic Bone Disease (MBD) Soft jaw, difficulty catching prey, lethargy Calcium/D3 deficiency; correct supplementation immediately; vet visit
Chytrid fungus Skin sloughing, lethargy, loss of righting reflex Serious fungal disease; vet visit immediately — antifungal treatment required

Water quality note: Always use dechlorinated or filtered water for the water dish and for misting. Tap water chlorine and chloramines are absorbed through the frog's skin and can cause serious illness over time. Let tap water sit out 24 hours or use a dechlorinator.

Quarantine all new animals for 60–90 days in a separate enclosure before housing near any other amphibians.
