Factors that impact the size of the Pacman frog

As long as it’s about the growth of a living animal, there has to be some sort of factors that can accelerate or stop the growth. The South American Horned Frog is no exception in this case. 

It’s crucial to know the details of factors so that the growth is not hampered and compromised. Let’s explore them below…

1. Genetics

Like any other organism in the universe, genetics play a big role in determining how big a frog will grow. The genes a frog gets from its parents will determine its size. This is another factor that humans can’t control.

When a frog grows up, it will also become big and strong if both of its parents are large and strong. In the reverse scenario, the situation is very different. If a Pacman frog is bred from a couple of frogs that are smaller in stature, the frog itself will never grow to the full maximum length.

2. Diet

The growth of a Pacman frog, or any animal for that matter, largely depends on its feeding habits and the food it’s eating. The better they eat, the bigger and stronger they get.

Feeding Pacman frogs is an especially tricky job. Because not only are these frogs on the larger side when pet frogs are concerned, but they also have a big appetite.

With increasing size, hunger levels increase as well. But owners often can’t gauge that. This causes underfeeding issues. So a lot of the times, they are left hungry and unhappy.

Moreover, these frogs hunt down other small Pacman as well, due to their insatiable hunger. That’s why you shouldn’t house them with other frogs.

As an owner, you have to feed your Pacman frog the best foods that are full of vitamins and minerals to ensure their growth. Also, you have to refrain from feeding them foods that are harmful to them, containing chemicals, unnatural hormones, and excessive amounts of fats.

In terms of staple food, cricket is the best choice for feeding the baby Pacman and adult Pacman. The size of the frog is a big indication of how much cricket they want to eat. A full grown size large Pacman can eat a whole cricket smoothly. 

Moreover, they will also love the mealworms, dubia roaches, and cockroaches as their staple food. Check out best food for pacman frogs here, if you don’t know what is good for them.

If you are thinking about how much meal these frogs want per day then again it’s about the size. A healthy adult Pacman eats a lot at a single meal. If your Pacman frog has a size less than 3’’ then provide them 3-4 crickets daily.

A full-grown adult or sub-adult Pacman frog requires a good meal 3-4 times per week. Make sure to properly dust the cricket with vitamins and calcium supplements. If this meal continues, your Pacman will become very big soon.

For proper growth, monthly/weekly treats for your Pacman frog will play a huge impact on their growth.

3. Temperature

Unfortunately, it’s common among frog owners to forget the importance of appropriate temperature for the best growth of Pacman. It’s impossible to have optimum growth without the optimum temperature.

When the Pacman frog spends a long time under the wrong or inappropriate temperature, its body function will slow down. As a result, they can easily fall into a hibernation mood, known as estivation.

During estivation, Pacman won’t eat anything as they will go hide under the substrate. Eventually, the frog will not have any growth for that particular time.

However, the moment they will get the right temperature and humidity which is 75-85 degrees Fahrenheit and 70-80%, they will come out of hibernation.

So, maintaining the perfect temperature leads to a bigger growth of the Pacman growth.

4. Breeding method

Your Pacman frog can become very big in their adult period if its breeding method was flawless. But that’s tough due to the different complications and risks in the breeding process.

Apart from being difficult, the procedure of breeding Pacman frogs is very susceptible to failure. So you have to be extra careful when breeding these animals, as the slightest of mistakes can cause the frogs to die.

Also, when the eggs are hatched, you have to take proper care of the tadpoles to ensure that they reach adulthood without dying.

If any single mistake happens during the breeding process, the tadpoles won’t be able to have the best growth. Tadpole management requires lots of effort and time too.

During this process, if they get enough nutrients and proper care, you can expect a perfect physiological development of your Pacman. And finally a bulky fat big Pacman in their adult life.

5. Stress

Stress is not visible so it’s a bit hard to track it. It can badly impact hormonal function and also neurological function. Both of these can affect the loss of appetite which will lead to problems in digestion and metabolism. When metabolism is affected, the growth limits, and there might be weight loss too.

To reduce the stress, you have to ensure a proper climate inside the frog’s tank. Some owners lack knowledge so they try to handle it with their hands often. It’s an extremely stressful experience for your Pacman frog. Due to their sensitive skin, they don’t feel good at all and can even bite you.

If you keep them with other frogs, they will also feel stressed. These carnivores amphibians are solitary by nature. The presence of another frog will ruin their mood and their stress level will be high.

If you as the owner provide a stress-free environment then wait for the big size of your Pacman frog. It will become big & round in no time.

6. Tank conditions

The conditions inside a Pacman frog tank play a huge part in their growth. These frogs come from wet and humid weather. So, you must maintain the proper humidity inside the tank.

Not only humidity, but temperature also has a hand in the growth of a Pacman frog. You must maintain optimum temperatures inside the tank at all times. If the temperature goes below 70 degrees Fahrenheit, Pacman frogs will go to hibernation. When they are in hibernation, the frogs stop eating, and as a result of which, they stop growing as well.

This is especially harmful to the growth of the baby and juvenile frogs. If they enter hibernation before reaching adulthood, their growth stops. If the babies don’t grow properly, they won’t reach maximum length as adults because of not having enough nutrition.

Another aspect of the tank conditions that is regularly overlooked is the comfort level of the frogs. When the Pacman frogs are stressed out, they stop eating. As a result, their growth stops. Also, being stressed brings about a lot of diseases, which also are a big obstacle in the way of the frogs reaching maximum size.
