Pacman Frogs (Horned Frogs): Setup, Humidity and Feeding
A Mouth With Legs
Horned frogs spend most of their time buried with only their eyes showing, waiting for something to walk past. The "pacman" name comes from their huge mouth and their habit of swallowing prey whole. Most in the pet trade are captive-bred. They're low-activity, low-space pets that suit people who enjoy watching rather than handling.
Housing: Small, Damp and Solo
LafeberVet gives 10 gallons (38 liters) as the minimum, noting they thrive in larger setups.
- Substrate: a damp, burrowable substrate such as unmilled sphagnum moss or a coconut-based mix, damp but not waterlogged.
- Water: a shallow dish of dechlorinated water the frog can sit in and climb out of easily.
- Cover: plants and leaf litter.
- One frog per enclosure: horned frogs will eat each other.
Heat and Humidity
- Day: about 75–82°F (24–27°C).
- Night: can drop to about 65°F (18°C).
- Humidity: about 80%, with regular light misting.
Avoid strong overhead heat lamps, which dry amphibian enclosures out. A low-wattage heat source on a thermostat, outside or above part of the enclosure, is safer. These are typical ranges from a veterinary information sheet; check with your vet or a specialist keeper.

A 10-gallon (38-liter) or larger enclosure with a secure lid is the base. Sphagnum moss or a coconut substrate holds damp for burrowing. A low-wattage heat source on a thermostat and a digital thermometer and hygrometer keep the climate right. A shallow water dish, a water conditioner and long tongs for feeding finish the setup.
Diet: Don't Overfeed
Feed gut-loaded insects and worms (crickets, roaches, earthworms) with long tongs. LafeberVet suggests dusting food with a vitamin and mineral powder two to three times a week for juveniles and once a week for adults. Horned frogs will eat almost anything that fits and become overweight easily, so adults need feeding only every few days. Rodents are very rich; many keepers avoid them or offer them only rarely.
Handling and the Bite
Horned frogs are always ready to eat, and their jaws have tooth-like ridges that can give a painful bite. Use tongs to feed, and handle as little as possible, with wet, powder-free gloves. Wash your hands afterward; amphibians can carry salmonella.
Health: Preventive Care
Find a vet who treats amphibians before you buy. Keep water clean and dechlorinated, the substrate fresh, and the frog at a healthy weight.
