The Amazon Milk Frog - Beginners Care Guide

The Amazon milk frog goes by a few different names. It’s also known as the Brazilian milk frog as well as the golden eyed tree frog and is a large arboreal amphibian. It’s found in the amazon rainforest as well as regions in south america. It was first discovered in Brazil, along the Maracana river. Measuring out of the 4 inches in length this means that these frogs are quite large for an arboreal species. by the time they reach adulthood they will have developed brown or black banding and will otherwise be grey. they can develop a slightly bumpy texture as they age and in captivity with proper care they can be expected to live for up to 10 years.


Amazon milk frogs will do well in a glass terrarium as their enclosure. This is because they need to stay cool and the glass is great at allowing heat to escape. Other various styles such as wooden vivariums are far too efficient at retaining heat so they are unsuitable.

When picking an enclosure for Amazon milk frogs, make sure you're choosing a vivarium with at least 450 mm in length and 600 mm in height. This is because they grow up to around 4 inches so they need the space large enough for them to move around in. secondly being arboreal they need enough space in the enclosure which gives them enough height to climb.


The vivarium you choose needs a constant air temperature of 75 degrees F on one side of the enclosure. The best way to achieve this is by sticking a large heat mat on one side of the glass enclosure. The heat mat will be regulated by using a thermostat to make sure the temperature doesn't exceed 75 degrees Fahrenheit. By placing the heat mat on one side of the glass this means that you'll also create a small temperature gradient within the enclosure which allows the frog to warm itself up or move to the colder side to cool itself down.

If you got a larger vivarium and it's not able to get up to the temperature with the heat mat alone you might be able to use a small basking bulb which will be implemented in the canopy, as long as the temperatures don't exceed 75 degrees Fahrenheit.


Amazon milk frogs come from the northern side of South America and animals that inhabit jungle regions do have some natural cover from leaves and branches and such but they still receive a fair amount of UV light. The UVB light source in your enclosure should reflect this. Generally in this type of enclosure you’ll want to keep your lights in a canopy above the mesh ceiling. You can either use a 5% to 6% UV tube or the equivalent compact light.

Amazon milk frogs require uvb in order to synthesise vitamin D3 inside of the skin and helps to absorb calcium which is crucial for bone structure and Growth. This is why reptiles can suffer from metabolic bone disease when not provided with adequate uvb lights.

We recommend that T5 tubes are replaced every 9 months and compact lamps are replaced every six months.


To increase the humidity inside the vivarium Amazon milk frogs should be kept on a slightly moist substrate. Bare in mind that any loose substrate has the potential to be accidentally swallowed. We found this not to be a problem with coarse orchid bark. It's also really easy to clean and if the humidity is not high enough with just this substrate then we recommend adding a small amount of moss to the enclosure, make sure you dampen this daily.


Amazon milk frogs frogs do like to climb on top of things to survey their surroundings. Because of this, the vivarium should be decorated with various pieces of wood, such as thick sticks and branches, which will enable them to do this. They're enclosure can be decorated with artificial plants to make it look more natural. You can also use wood ornaments that look very effective when trying to mimic their natural habitat, and they also provide further places for the frogs to sit on. You're bound to have electrical wires and equipment, and trailing plants are very good at disguising these - they also provide a safe space for young amphibians.

Feeding and Diet

Amazon milk frogs are carnivorous which means they have a diet consisting mainly of livefoods, the core of which should be high in protein and relatively easy to digest. You can use foods such as brown crickets, black crickets or locusts and occasionally to give variation you can offer other bugs such as mealworms, wax worms or calci worms.

To provide hydration you should mist your vivarium every morning with water from a spray bottle. A water bowl may also be introduced as a source of Freshwater and give your frogs a place to splash about if they want to.

Supplementation in the form of calcium, vitamins and minerals should be given to create an optimal nutritional diet for your Amazon Milk frog. You can buy these mainly as powders and simply dust off their food before feeding them. If you’re giving them any live food make sure it's gut loaded with insect food. Basically this means that the live food is fed a nutrient rich diet before they’re fed to the Amazon milk frog.
