Pacman Frog / Horned Frog Care Guide

Ceratophrys spp.

Terrestrial Ambush predator Welfare-forward care

Pacman frogs are heavy-bodied terrestrial ambush predators that spend much of their time partially buried. Their sedentary behavior does not justify a barren enclosure or outdated survival-level husbandry.

Husbandry standards note: this guide intentionally avoids outdated bare-minimum practices such as treating a 10-gallon tank as ideal permanent adult housing, keeping the enclosure uniformly swampy, using bottom heat, or feeding rodents as a staple.

Permanent Enclosure and Substrate

For adults, Red Rocks recommends at least a 24 x 18 inch footprint with enough height for 4-6+ inches of soft, diggable substrate and a safe lighting gradient.
A 10-gallon tank can serve a small juvenile or quarantine animal, but should not be treated as the ideal permanent adult setup.
Use a soil-like, fertilizer-free substrate with leaf litter; avoid chunky bark, gravel, calcium sand, wood shavings, reptile carpet, and other abrasive or readily swallowed materials.

Lighting and Heating

Provide a 10-12 hour white-light day/night cycle with real shade; do not use colored night bulbs.
Low-level Ferguson Zone 1 UVB is recommended when a true gradient can be created; roughly UVI 0.5-1.0 at the exposed usable surface with near-zero shaded retreats is a conservative target.
Maintain roughly 75-80Â°F through most of the enclosure with a warm area around 80-82Â°F; use gentle overhead heat on a thermostat and never rely on bottom heat or heat rocks.

Humidity and Water

Aim for roughly 60-80% humidity with temporary rises after misting while allowing parts of the surface to dry slightly.
Lower substrate should remain evenly moist like a wrung-out sponge, never muddy, sour, or waterlogged.
Provide a wide, shallow soaking dish with amphibian-safe water and change it daily or whenever soiled; untreated tap water and routine distilled soaking water are inappropriate.

Diet and Supplementation

Use a varied diet based on nutritious, captive-produced invertebrates such as earthworms, dubia roaches, crickets, and silkworms.
Do not power-feed. Adults commonly begin around one moderate meal every 5-7 days, adjusted to body condition; rodents are optional rare prey, not a staple.
Gut-load feeders and use a consistent calcium, D3, and multivitamin plan that includes usable preformed vitamin A rather than relying only on beta-carotene.

Handling, Cohabitation and Health

House one Pacman frog per enclosure. They are opportunistic predators and cohabitation can cause serious injury or cannibalism.
Routine handling provides no benefit; move frogs with a clean damp container or moistened powder-free nitrile gloves when necessary.
Monitor for obesity, metabolic bone disease, vitamin A deficiency, impaction, skin disease/red-leg signs, edema, breathing problems, neurological signs, or meaningful weight loss and seek an amphibian-experienced veterinarian when indicated.
