The Pacman frog, or South American Horned frog, is a charming amphibian. They are popular pets due to their unique appearance and engaging behavior, but many people wonder whether they should purchase a male or female. While both have many similarities, there are a few notable differences, so keep reading as we discuss size, vocalizations, breeding, and personality to help you understand the difference between the two sexes and make an informed purchase.
Pacman frogs (Ceratophrys ornata) are popular exotic pets known for their big appetite and wide mouth. An important aspect of caring for these frogs is being able to determine their gender, as males and females have some different requirements.
In this comprehensive guide, we’ll cover everything you need to know about identifying the sex of your pacman frog, including when they reach sexual maturity, key physical differences between males and females, and proven methods to tell them apart.
Why Identify Your Pacman Frog’s Gender?
There are a few key reasons why you’ll want to figure out if your pacman frog is male or female:
-
Enclosure size – Females grow larger than males and need more space. A 20 gallon tank is recommended for females, while a 10 gallon may suffice for a male.
-
Behavior – Males vocalize more with croaking and may be more aggressive. Knowing the sex can help you understand their behavior.
-
Breeding – If you want to breed pacman frogs, you’ll need a confirmed male and female pair. Identifying gender is essential.
-
Placement – Loud male croaking may impact where you place the terrarium. Bedrooms are less ideal for noisy males.
So while not absolutely vital, confirming gender can be very useful for caring for and breeding pacman frogs.
When Can You Identify Gender?
Pacman frogs take around 12-18 months to reach full maturity. While you may be able to sex younger frogs, mature adults will show the most pronounced sexual differences.
Key points on sexual maturity:
-
Frogs can be sexed from 7-8 months old, but 12-16 months is better.
-
Wait until at least 12 months old for clear sexual characteristics.
-
At around 18-24 months, breeding age is reached.
Ask the breeder or seller the age of your frog if possible. Trying to identify gender too early can lead to mistakes. Be patient and wait for maturity.
Male vs Female Differences
Mature male and female pacman frogs exhibit some clear physical and behavioral differences:
-
Size – Females are larger, up to 7 inches long. Males reach around 4 inches maximum.
-
Pads – Males develop dark nuptial pads on their thumbs for gripping females when breeding. Females lack these pads.
-
Color – Males can show more color variation like green, yellow or lime. Females are often plain brown or tan.
-
Chest – Males have a darker “beard” on their chest. Females maintain a pale chest.
-
Croaking – Males vocalize more with a loud distinctive croak. Females may chirp, but not croak.
-
Aggression – Mature males tend to be more aggressive, especially in breeding mode.
With those distinguishing characteristics, an experienced keeper should be able to positively identify the gender once the frog is mature.
7 Ways to Determine Pacman Frog Gender
When trying to identify the sex of your pacman frog, look for these characteristics:
-
Check for nuptial pads – The dark thumb pads present on mature males are the most reliable indicator of sex.
-
Compare size – Check if your frog is small (male) or significantly larger (female).
-
Inspect coloration – Note any bright colors which suggest a male, versus plain brown of females.
-
Look at the chest – Males will develop a darkened “beard” on their chest as they mature.
-
Listen for croaking – Males may croak when fed or misted. Females rarely vocalize.
-
Feel thickness of arms – Males have more muscular front arms compared to females.
-
Examine aggressiveness – Mature males often act more aggressively, especially in breeding mode.
With adult pacman frogs, the presence of dark nuptial pads in males offers the most definitive way to confirm gender. When multiple signs point to one sex, you can be confident identifying whether you have a male or female.
Can Males and Females be Housed Together?
Pacman frogs are solitary creatures that should always be housed alone, regardless of gender. They are cannibalistic and will attack other frogs sharing an enclosure.
The only exception is during supervised breeding. A male and female can briefly be put together for mating after proper conditioning to stimulate them reproductively. Once breeding is complete, they must be separated.
For regular housing, never keep two pacman frogs together in one tank. Their aggressive and solitary nature make roomates unsafe. Raising frogs individually is best for their health and wellbeing.
Identifying your pacman frog’s gender takes some patience for them to mature, but clear physical and behavioral differences emerge with adulthood.
Looking for nuptial pads, size, coloration, croaking, and aggressiveness provides reliable ways to determine if you have a male or female once they pass 12 months old. This knowledge allows better care and is key for breeding.
Remember, pacman frogs should always be housed alone due to their cannibalistic tendencies. Only put a male and female together briefly under close supervision for mating purposes.
With the right information and comparisons, you can confidently sex your adult pacman frog. Use these tips to get to know whether your frog is a boy or a girl!

Pacman frogs get their name from their distinctive round shape and wide mouths, resembling the famous video game character Pac-Man. This frog has a flat stocky, sturdy body with a wide and round head, large eyes, and a wide mouth extending beyond their eyes. Their skin has plenty of warty bumps that help them blend in with their surroundings. Pacman frogs are native to the rainforests of South America, and you will find them in Brazil, Argentina, Paraguay, and Uruguay. They come in many colors and patterns, including shades of green, brown, yellow, and orange, and there are several species with the same name that can vary in size and color. They are voracious eaters with a diet of insects, small rodents, and even other amphibians.
Male Pacman Frog Overview
Male Pacman frogs are vocal and use their vocal sacs to emit various croaking sounds. The intensity and frequency of the vocalizations vary between individuals, and many owners describe them as quite entertaining. Male Pacman frogs are more territorial than females, especially during the breeding season, and can become aggressive toward other frogs. They are also curious and enjoy exploring their surroundings and can get quite excited when you present them with food.
Unfortunately, Pac-Man frogs have limited cognitive abilities and can be difficult to train. However, you can help improve your interactions and provide mental stimulation with positive reinforcement techniques. For instance, when they do something good, like stay calm while being handled, you can treat them to help create a positive association with that behavior. Establishing a consistent feeding routine can also help your frog associate you with the food that they are receiving, which can help strengthen your bond and make them more likely to allow you to handle them.
Maintaining your male Pac-Man frog is relatively easy. They need about 1 square foot of space, so a 10- to 20-gallon tank should work fine, but try to provide as much space as possible. You must keep the temperature at 75–85 degrees Fahrenheit during the day, but you can cool it down a little at night. They need a substrate that retains moisture, like coconut fiber or moss, and you will want to keep humidity in the tank at 60% to 80%. They are nocturnal but still need a low-level source of UVB lighting for a few hours each day to get enough vitamin D3. They also need plenty of live food each day, including crickets, roaches, mealworms, and wax worms, and you will need to dust the food with calcium and vitamin supplements to ensure proper nutrition. They require plenty of fresh, clean, dechlorinated water.
Male Pacman frogs usually reach sexual maturity at 1–2 years. They will start to display certain physical and behavioral signs, like increased calling or croaking, darker or more vibrant coloration, and a general increase in activity and territorial behavior. If you want to breed the frog, you will need to create a separate enclosure with plenty of substrate and hides that he can use to build a nest to attract a mate before introducing the female.Male Pet Breed Pros

How do you tell if a frog is a male or a female?
Generally females will be larger than males and the little disk think next to their eyes (the tympanum) will look different. The throat can help tell also, if it’s darker it’s likely a male.
