Ultimate Pacman Frog Diet Guide: Top Foods to Keep Your Horned Frog Healthy and Thriving

Pacman frogs, also known as South American horned frogs, are popular pets among reptile enthusiasts due to their distinctive appearance and relatively low-maintenance care needs. These frogs, named after the classic arcade game character, can grow to about 6 inches long, with females typically larger than males, and are about as wide as they are long. They are not truly aquatic, preferring to hide under leaf mold on the forest floor, waiting to ambush passing prey. Understanding their dietary needs is crucial for keeping these unique frogs healthy and happy. This comprehensive guide will delve into the specifics of a Pacman frog's diet, including what to feed them, how often to feed them, and what to avoid.

Understanding the Importance of a Proper Diet

Pacman frogs are carnivorous by nature, relying on a high-protein diet that mirrors what they would eat in the wild. Being well-informed about their appetite isn't just about their physical health-feeding them appropriately also influences their behavior. A balanced diet prevents lethargy or aggression while fostering vitality.

What Do Pacman Frogs Eat?

Pacman frogs are not picky eaters and will consume a variety of food items. In the wild, they are known to eat other amphibians, small reptiles, and even birds. In captivity, their diet should primarily consist of:

Insects: The bulk of a Pacman frog's diet should consist of insects like crickets, roaches, and mealworms. Crickets are particularly popular since they're easy to source and great at providing protein. When supplying prey items, it is best to leave worms wriggling in a small, very flat dish or to dangle with forceps. Crickets will provide their own motion and eventually wander into harm’s way.
Worms: Pacman frogs adore a juicy worm! Earthworms and nightcrawlers rank high among frog fanatics for being nutrient-rich and easy to digest.
Small Vertebrates: Growing Pacman frogs may enjoy pinky mice or other small vertebrates. It is recommended to feed rodents to adult Pacmans only once every 2 or 3 weeks. The reason for feeding pinkies and fuzzies (mice infant mice a couple of weeks old) sparingly is that they can contribute to obesity in your frog.
Commercial Frog Food: For an easy option, try using ready-made Pacman frog food like Zoo Med Pacman Frog Dry Food.
Feeder Fish: Live feeder fish like guppies can occasionally be offered as a protein-packed treat.

It is essential to offer a variety of food items to ensure they are getting all the nutrients they need.

Feeding Schedule and Portion Control

Feeding your Pacman frog isn’t just about offering the right foods-it’s also about timing and portion control.

Feeding Frequency: Juvenile Pacman frogs can be voracious eaters, requiring meals every day or every other day. Pacmans smaller than 3 inches in length should be fed daily whatever they can consume in under 30 minutes, generally 3-4 crickets or the equivalent. Once they’re adults, they’ll need feeding just 2-3 times a week. Sub-adults and adults should be fed 2-3 times a week in the same manner. Babies eat daily, juveniles every other day, and adults just 1-2 times per week.
Portion Size: Portions should be based on the size of your frog. A general rule of thumb is to never feed anything larger than the space between their eyes. The size of the prey you choose will depend on whether or not the frog can both swallow and digest it. When in doubt, consider the width of the diner. That is, prey should be no wider than the widest part of the frog's body.
Feeding Time: Most Pacman frogs are nocturnal, so offering food in the evening aligns with their natural hunting instincts.
Avoiding Overfeeding: Be careful not to overfeed. Signs your frog is eating too much include obesity (yes, frogs can get chonky!) and regurgitation.
Monitoring Weight: Watch for unhealthy weight gain or stunted growth-it can often point to underfeeding or nutrient imbalance.

Supplementation

Even if you’re careful with food variety, supplements are sometimes necessary to fill in any gaps in your Pacman frog’s diet. As with any reptile or amphibian being fed a mostly insect diet, it's important to think about supplements.

Calcium: Calcium is vital for a frog’s bone health. Dust your Pacman frog’s prey with a calcium powder a couple of times a week. Calcium supplementation should be added to the food weekly. Vitamin D3 helps process calcium which is needed for strong bones. Without it, they’re prone to developing MBD (Metabolic Bone Disease). It’s important to use a calcium supplement with vitamin D3.
Multivitamins: Multivitamin powders provide essential nutrients not always covered by their live prey. A multivitamin supplement should be added every 2 weeks.
Gut Loading: Want to make those mealworms extra nutritious? Gut-load them for at least 24 hours before feeding. “Gut loading” means placing the feeder insects on an enriched diet for at least 24 hours prior to being offered to your Pacman. This enhances the nutritional value of the insects substantially. A purchased supplement such as those offered by reptile hobby stores is easily available and affordable. The convenience of a dry gut load diet, purchased from a pet supply house, is undeniable.
Hydration: Though not technically a “supplement,” make sure their enclosure includes a damp substrate like Galapagos Tropicoco Coconut Soil.

Foods to Avoid

Just as important as knowing what to feed your Pacman frog is understanding what NOT to feed them. While their appetites might seem endless, not every snack is a safe choice.

Avoid: Raw meat, cooked food, or anything processed.
Hard-to-Digest Prey: Prey that’s too hard (e.g., large beetles or hard-shelled crabs) can injure your Pacman frog’s mouth or digestive tract.
Toxic Insects: Some bugs, like fireflies, are highly toxic to Pacman frogs.
Live Rodents: Live rodents should not be fed to frogs.

Understanding Your Pacman Frog's Appetite

Pacman frogs aren’t picky eaters, but they do have individual quirks. Noticing what they prefer or how their appetite changes over time is a sign of good caretaking. Changes in appetite can signal health issues. A sudden refusal to eat could indicate stress, illness, or improper environmental conditions, like temperature or humidity. Over time, you might notice your frog favoring specific foods.

Additional Feeding Tips

Offer Dead Prey with Forceps: Dead mice are best offered by using forceps to avoid being bitten. It is not recommended to feed these frogs from your hand as they have a powerful and painful bite. Placing the food in a dish or on a flat rock or dancing a dead food item with forceps is a better option.
Thawing Frozen Prey: Pre-killed offerings can last in the freezer for up to six months. Remember to thaw it completely in the refrigerator and warm it to slightly above room temperature before feeding it to your frog. Do not use a microwave for this. Put the frozen food in a sealed plastic bag and place it in a thawing container filled with cold water. Keep the food in the water until it thaws. Place the thawed prey, still in the sealed plastic bag, in the warm water. Never use a microwave to thaw or warm frozen rodents, and never offer food that's still frozen to a pet. Avoid preparing frozen rodents in the same area that you use to prepare food.
Live vs. Pre-Killed Prey: Some keepers believe that the live prey offers the ability for the frog to perform natural behaviors. Others claim that this is nonsense and that a rich environment should provide sufficient stimulation. Attacks by live prey can permanently disfigure your frog. Injuries caused by live prey can include lacerations to the frog's mouth area and eyes.

Creating the Ideal Habitat

In addition to a proper diet, maintaining the correct habitat is crucial for your Pacman frog's overall health and well-being.

Enclosure: Aggressive and carnivorous frogs should always be housed alone due to their tendency towards cannibalism. If desired, juveniles under 3 inches can be maintained in a 5-gallon aquarium for a while (about a year). Some keepers find that using a non-conventional enclosure such as plastic storage boxes is less stressful for the Pacman frog due to the opaque nature of the sides. The drawback, however, is that an opaque container will limit visual access to their pet. And this will also hide specific habitat conditions that an owner should be looking for. A multitude of sins can go unnoticed when viewing an enclosure from the top only.
Substrate: The ideal substrate for your frog is one that can be kept very damp (not sopping) without falling apart, mashing down, or growing mold or fungus. You may find that some inexperienced keepers use shredded cloth towels as a substrate. But the reality is that fabric substrates can be stressful for Pacman Frogs because it doesn't do a good job replicating their natural environment. In the wild, they spend the majority of their time buried up to the eyes in sand or leaf litter. For this reason, towels and even sphagnum moss may be too bumpy and clumpy. Many keepers use a high humus content topsoil. If not purchased, then it must be baked in the oven at 350 degrees F for ½ hour, only then can a natural, yet sterile soil substrate be achieved. Cook 2 batches at once for efficiency. If you don’t want your dwelling smelling like toasted compost, yet you want the best for your pet, then a commercial product such as Exo Terra plantation soil or Zoo Med Eco Earth may be the ticket. Regardless of the choice of substrate selected, it needs to be moistened at all times with dechlorinated water. Tap water that has been dechlorinated chemically or “aged” is perfectly fine. To age water, allow chlorinated water to sit in an open container for 24-48 hours so chlorine can dissipate. Alternatively, you can use bottled spring water. Please note that with most amphibians, lizards, and many frogs, sand is not the best substrate. For instance, in the case of the Pacman, the tongue is folded over inside the mouth. To capture a potential meal, the frog will drop its lower jaw with considerable force, causing the tongue to flip over and out of the animal's mouth, seizing the prey.
Hides: As mentioned earlier, very little in the way of elaborate furniture is needed for your Pacman. A nice round hide will give your Pacman a dark place to disappear into for a while. Your Pacman will probably create a smaller burrow under the hide. As in the wild, they will bury themselves completely except for their eyes. The material the hide is made of is not as important as its size and shape. The hide should be a half round of cork or a reptile log. While your Pacman is growing, cork is a nice choice. The drawback with cork is that it cannot be sanitized more than about 8 times without falling apart. Your frog is going to need no more than an inch of clearance on each side of his/her body. Hides that are too large or too small won’t be used. The space will seem either too spacious or too small to get in and out of without getting stuck.
Plants: If you wish to include live plants for aesthetics, many keepers recommend attaching epiphytes to the sides of the habitat. Elevating plants keeps the Pacman from smashing them flat, and epiphytes are super low maintenance, which will make up for the aquarium maintenance you will need to do weekly.
Temperature: Even though these frogs are indigenous to tropical South America, they do best when the room temperature resembles the conditions underneath leaves on a cool forest floor. The mid to high 70s suits them well. Therefore, depending on your household’s ambient temperature, your frog may not need supplemental heat. If your home is kept on the cool side, then an undertank heating pad is advised. Maintain habitat temperatures of 75-83 F during the day and 70-75 F at night and check the temperatures of your frog’s habitat daily. Two thermometers-one in the warm area and one in the cool area-should be placed in the enclosure so that both zones can be checked at once.
Humidity: Pacmans need plenty of humidity at levels between 70 - 80%. If there is no swimming/total immersion area within the habitat, then monitoring the levels daily is essential. The best way to monitor humidity in the habitat is with a hygrometer. In addition to a nice wide water bowl, the required humidity can be achieved by misting the frog’s enclosure twice a day. Once in the morning and once again in the afternoon (for this species once a day is not enough). If the hygrometer shows that levels are still not being reached, just mist a few more times throughout the day. Consistency in misting and frequent monitoring is critical. They aren't like bearded dragons, where the room's natural humidity levels are adequate. The humidity, especially during the day for this diurnal species, must be within the comfort range mentioned above. But it's also important that it's not overly misted. Too much humidity can create standing water at the bottom of the habitat (anywhere not within a bowl or swimming area). So, while keeping the relative humidity high, you must also be very careful not to over saturate the substrate with water. This will cause the substrate to rot, which will resultant in bad effects on your frog’s skin and overall health. Humidity levels should be maintained between 70-80% and monitored with a humidity gauge, called a hygrometer. Be sure that the substrate is damp but not wet.
Water: Frogs should always have access to a shallow bowl of dechlorinated water in their habitat that’s wide enough for them to soak in. Pacman frogs should have constant access to an open, shallow bowl of filtered and dechlorinated water (never use distilled or tap water) in which they can soak and drink. The bowl should be surrounded by plants, such as pothos, to create coverage and help frogs feel safe while drinking and sitting in the bowl.

Maintaining a Clean Habitat

Frequent cleaning of the tank is necessary because of the prodigious amount of feces a healthy and well-fed adult Pacman frog can pass.

Spot Cleaning: Every other day removal of poo is highly recommended.
Deep Cleaning: Remove everything, and spritz the habitat interior with 10% bleach solution. If the terrarium is glass, spray sides with vinegar after the bleach has been applied and removed and wipe down for better visibility. After wiping down, wait another ½ hour, install fresh substrate and reposition the sanitized furniture. Only then should you place your frog back in. This is one time where a separate container for you frog is handy. If using supplemental heat beneath a Tupperware or other plastic box, be sure to slip a hand towel over the heating element so it does not come into direct with the plastic. For better viewing of your pet through glass, cleaning strength vinegar on the glass sides is fine as long as used in moderation, wiped off thoroughly and then the glass allowed to dry and off-gas. This should be done for the dry side only, unless the wet side has been drained for cleaning as well. Remember, unlike fish and reptiles, an amphibian’s skin is extremely porous and sensitive. They do not drink water, but rather absorb water and sodium directly through the skin. Therefore, you do not want your friend to have to hydrate himself/herself in an acid bath, or the equivalent of lye either. So no vinegar must be allowed to remain in the habitat. Fish and reptiles do not share this epidermal sensitivity with amphibians, so do not make assumptions in this regard. Any objects removed from the habitat and sterilized with bleach or vinegar must, must, must be thoroughly rinsed in aged water and then allowed to dry for 2 hours before it re-enters the habitat. It is important that new keepers understand the importance of this additional step in maintaining a sterile, yet pH neutral environment for their frog. Frogs continually exposed to chemicals may display ‘toxic-out’ symptoms such as erratic jumping and spastic extensions of the hind limbs, listlessness, and cloudy eyes. If this is observed, immediately place your distressed and miserable pet in a dish of slightly warm distilled water. Leave them in there and put them back in if they jump out.
