Pacman frogs are large, round frogs with big mouths and some yellow skin color — think Pac-Man, the video game phenomenon of the early 1980s. Pacman frogs (genus Ceratophrys) are also called ornate horned frogs and South American horned frogs. At maturity, female pacmans can reach 7 inches long and 7 inches wide Males are smaller compared to females, reaching up to 4 inches across. You can keep no more than one pacman in a tank, since the creatures are cannibalistic. Having a pacman frog is a long-term commitment; an individual can live to be 20 years old.


Pacman frogs are often inactive, therefore they don’t require plenty of space. A 10- to 20-gallon aquarium using a tight-fitting lid is sufficient. Lay a substrate of sphagnum moss, peat moss or coir deep enough for the specimens to burrow in. Pacmans spend most of their time buried as much as their eyes in the damp substrate. Live plants provide hiding places and help to maintain humidity levels.

Water and Humidity

Pacman frogs don’t drink plenty of water, they absorb moisture through their skin. Bury a shallow bowl of chlorine-free water to your depth that’s level using the substrate which means that your frogs can easily go to it for soaking. Pacmans don’t swim; they can drown in deep water. Keep your substrate damp by misting it a couple of times daily. Spray it more regularly should you live in a dry climate or maybe your house is air-conditioned.

Temperature and Lighting

Pacman frogs are cold-blooded animals who can’t regulate their body temperatures. They’re comfortable in ambient temperatures of 65 to 85 degrees Fahrenheit. Place your tank from sunshine to stop overheating. Broad-spectrum lights are good for plants and frogs. Provide 12 hours of light and 12 hours of darkness daily.


Pacman frogs have big appetites; they’ll will eat anything that moves. Careful feeding, though: They’ll bite at fingers, mistaking them for food. Pacmans eat only live food, ambushing their prey. Small frogs require a varied diet of crickets, mealworms and waxworms. Feed your pacmans daily, and dust the feeders with vitamin powder every other day. Medium frogs will eat pinkie mice, while large frogs enjoy small mice and pinkie rats every several days.

Habitat Maintenance

Clean the pacman’s tank one or more times a week. Wash the hands before handling your pacman frog — because oils on human skin can be toxic to him — and after handling him to minimize chance of salmonella poisoning. Gently remove him from the tank and place him in another container. Eliminate the substrate from the tank. Clean the tank with hot water and rinse off the plants. Don’t use soap or detergent. Clean the substrate before replacing it, or use new substrate.


Keep the pacman frog’s habitat damp at all times, although not wet. In the event the substrate becomes dry and your frog seems to be dead, attempt to rehydrate him. Each time a pacman frog becomes dehydrated, his outer skin gets dry and tough as his body qdfwly measures to conserve moisture. He becomes motionless and appears to have died. He may still be alive. If you rehydrate him before death occurs, he’ll shed his outer skin and eat it.
