Amazon Milk frogs are found throughout the Amazonian Basin, below 800m in elevation. They are called ‘Amazon Milk Frogs’ due to the release of a milky white substance excreted from the frog’s back when threatened (this rarely occurs with captive bred animals). They have also been called Amazon Cave Frogs and Gold Mission Frogs. These are a great beginner tree frogs that are relatively easy to keep and can be kept individually or in groups., They should be considered a viewing pet in generally, and not held more than necessary.
Enclosure: These are a larger frog, requiring at least a 29g aquarium or 18x18x24 terrarium for two adults, adjusting the size according to the number of frogs. The enclosure should provide plenty of perching areas, such as wood branches or vines, as well as live or fake plants. For younger Amazon Milk Frogs, moist paper towel or long fiber sphagnum moss is preferred, while adults can also be kept above water instead of a substrate, with the water or substrate changed regularly.
Temperature & Humidity: They can tolerate temps of 70-85F, with mid/high 70s being ideal during the day, dropping 5-10 degrees at night. A good Thermometer and Hygrometer is necessary to monitor environmental conditions. In the wild precipitation and humidity fluctuates based on season, so these frogs can handle a wide range of humidity levels, preferring 50-70% with plenty of ventilation. Young Amazon Milk Frogs do best with humidity kept closer to 70-80% with some air movement. Stagnant air is a big no-no with milk frogs, as very young animals dry out easily, so routine spraying and a full screen top will aid in maintaining humidity levels.
Size: Adult Amazon Milk frogs reach sizes of 3-5 inches as adults, with females being larger than males. They will continue to grow throughout their lives, so older animals can get quite large.
Age: Captive life span of the Amazon Milk Frog is unknown, but suspected to be in the 5-10 year range, based on experience with similar species.
Diet: These frogs are voracious eaters, consuming anything that moves and fits into their mouth. A staple diet of appropriately sized crickets is a great place to start, mixing in a variety of feeder insects such as wax worms, roaches, horn worms, and meal worms, even with the occasional pinky mouse once they are large enough. A calcium and vitamin supplement powder should be used on a weekly basis as well. They also need a large water bowl, which should be thoroughly cleaned and refilled daily.
A Special Note on Shedding: All frogs and toads shed, but they don’t always do it in public! Amazon Milk Frogs are not shy about it whatsoever, and will typically shed at least once a week. They’ll develop a shiny appearance for a few hours, before using their legs to peel off the old skin, then eat it. During this time, the milk frog will generally hang out at the bottom of the tank. Do not be alarmed – this is completely normal behavior, even though it looks a little strange!
