Pacman Frog Care Sheet

Ceratophrys spp.

By Carolina Cricket Farm. Last updated: November 2026. Reviewed against published veterinary care guidance.

Pacman (horned) frogs are a beginner-friendly amphibian [1] that sit buried in damp substrate and ambush their food. Males grow to about 3 to 4 inches and females 4 to 8 inches [1], and they can live 10 to 15 years with proper care [1]. Here is the setup, temperatures, humidity and feeding routine, with every number sourced.

Pacman Frog Enclosure and Setup

Pacman frogs don't move much, so they don't need a big tank. Give at least a 10- to 20-gallon habitat that is wider than it is tall, with a tight-fitting screened lid to stop escapes and keep air moving [1]. Merck adds that amphibian enclosures need good ventilation and secure, ventilated tops [2].

  • About 3 to 4 inches of substrate for adults. Coconut fiber and sphagnum moss hold moisture and let the frog burrow; leaf litter on top looks natural [1].
  • Skip reptile carpet, artificial turf, gravel and rocks. They scratch delicate skin, and swallowed gravel can cause a fatal blockage [1].
  • A shallow, open water bowl big enough to soak in, with plants such as pothos around it for cover [1].
  • One frog per enclosure. Pacman frogs are territorial and may eat each other, and never mix species [1].
  • Use chlorine- and chloramine-free water and never distilled water, because amphibian skin absorbs what is in the water [1][2].

Pacman Frog Temperature

Keep the habitat at 75 to 83°F during the day and 70 to 75°F at night [1]. Merck warns that amphibians kept outside their preferred range can become immunosuppressed and pick up infections [2].

Time Target
Day 75 to 83°F [1]
Night 70 to 75°F [1]

Heat with a low-watt incandescent bulb, an under-tank heating pad or a ceramic heat emitter, always on a thermostat. Never use hot rocks [1]. Check temperatures daily with two thermometers, one in the warm area and one in the cool area [1].

Pacman Frog Humidity and Water

Keep humidity at 70 to 80% and check it with a hygrometer [1]. Mist the substrate with dechlorinated water at least once a day so it stays damp but not wet [1]. Too much moisture grows mold and bacteria that cause skin and breathing infections; too little dries the frog out [1].

Clean, disinfect and refill the water bowl every day [1].

Lighting and UVB

Use a low-level (2.0 or 5.0) UVB bulb for 10 to 12 hours a day, on a day and night timer [1]. Merck says UVB lighting is required to prevent metabolic bone disease in amphibians, and bulbs should be replaced every 6 to 8 months or as the manufacturer directs, even if they still light up [2][3]. Glass blocks UVB, so don't shine it through glass [3]. At night, turn lights off or use a nocturnal or infrared light [1].

What to Feed and How Often

Feed a variety of gut-loaded insects and worms: crickets, Dubia roaches and earthworms are good staples [1]. Mealworms and waxworms are high in fat, so treat them as an occasional treat [1]. Adults can also have a frozen-thawed rodent every other week, never a live one and never microwaved [1]. Always feed with tongs; Pacman frogs bite [1]. Banded crickets are naturally resistant to the cricket virus that wiped out many house-cricket farms, and ours are virus-free and parasite-free. We use a special high-quality cricket feed and have a state-of-the-art watering system.

The size rule: prey no bigger than the width of your frog's head. When in doubt, size down [5].

Age How often CCF banded cricket size Dubia
Juvenile (until adult size at about 6 to 12 months [1]) Daily [1] Small 1/4 to 3/8" [5] Small (about 3/8") [7]
Adult 1 to 2 times a week [1] Large 3/4" Medium or Large [5]

Sizes from our frog feeding guide and Dubia size chart. Large is the biggest cricket we suggest for adult Pacman frogs. Pacman frogs overeat easily, so offer a few insects per meal rather than a big pile [5]. Dubia roaches can't ship to Florida. Ask a veterinarian who treats amphibians about your frog.

Gut-Loading and Dusting

  • Gut-load insects for at least 24 to 72 hours before dusting and feeding them [1]. See what do crickets eat.
  • PetMD advises a calcium supplement with vitamin D daily and a multivitamin made for amphibians once a week [1].
  • Merck notes amphibians can't make their own carotenoids, so they need a vitamin A source in their supplements [3].

Handling and Shedding

Pacman frogs are best watched, not held. They bite, and human skin oils and soaps can harm their skin. If you must move one, wear powder-free gloves wet with dechlorinated water, and wash your hands before and after, since frogs can carry Salmonella [1].

Healthy frogs shed in one piece and usually eat the old skin. Skin that looks thick and dull can mean humidity is too low [1].

When to See a Vet

  • Dry skin, skin sores or redness on the legs and belly [1].
  • Cloudy, swollen or bulging eyes, or eye or nose discharge [1].
  • Not eating, weight loss or lethargy [1].
  • Discharge or blood from the mouth, or bent or broken toes [1].

Book a wellness check once a year [1]. Find a vet through the Association of Reptile and Amphibian Veterinarians [4].

Pacman Frog Care FAQ

How do you take care of a Pacman frog?

Keep one frog in a 10- to 20-gallon tank that is wider than tall, with 3 to 4 inches of damp coconut fiber or moss, 75 to 83°F by day and 70 to 75°F at night, 70 to 80% humidity, a shallow water bowl and gut-loaded insects [1].

What temperature does a Pacman frog need?

75 to 83°F during the day and 70 to 75°F at night [1].

What humidity does a Pacman frog need?

70 to 80%, checked with a hygrometer, with daily misting of the substrate [1].

Do Pacman frogs need UVB?

Yes. Use a low-level 2.0 or 5.0 UVB bulb for 10 to 12 hours a day [1] and replace it every 6 to 8 months [2][3].

How often do Pacman frogs eat?

Juveniles daily and adults 1 to 2 times a week [1].

What size crickets for a Pacman frog?

No wider than the frog's head [5]: Small crickets for juveniles and Large crickets for adults.

Can you hold a Pacman frog?

It isn't recommended. They bite and their skin is delicate; use wet, powder-free gloves if you must move one [1].
