Recommended Vivarium Size

The Reticulated Glass frog is very arboreal, so a male and female pair should live in a 20 gallon or an 18x18x24 front opening tank.

These frogs will need a lot of vegetation in their tanks to feel comfortable as they are fairly shy during the day. Either live or fake plants can be used so long as the leaves are large and provide ample hiding spaces. 

A water dish of clean water should be provided for these frogs at all times.

Either biobedding or ABG mix topped with sphagnum should be provided for substrate.

For Breeding conditions, a water feature with moving water is required to stimulate breeding.


The vivarium should be between 72 and 78 degrees Fahrenheit. Always use a thermometer or combometer to monitor the temperature in the tank. 


Humidity should always stay around 50% and 70%. Use a hygrometer or a combometer to monitory the humidity in the tank. 


Males are ¾ ” and females are slightly larger at just under 1”


The Reticulated Glass frog can live for about 5-8 years but may live longer with ideal care.


As adults Reticulated Glass frogs can eat ⅛ ” crickets and Hydei Fruit flies. They can also be fed similarly sized insects. Dust feeder insects with a quality calcium and D3 supplement at least 2 times a week, and a multivitamin at least once a week. We offer food every evening.


Male Fleischmann’s Glass frogs will be slightly smaller than females and emit advertisement calls. A male’s call is a light “sheet” but can also emit a “squeak” when it’s territory is invaded by another male.

Males also have  white nuptial pads.


Reticulated Glass frogs are light green with light yellow circles that mimic their egg clutch. The glass frogs call to fame is its partially transparent underbelly. The internal organs are covered by a white guanine sheet and are visible.

Social Behavior

Male Fleischmann’s Glass frogs are very territorial and will fight and potentially kill other males. It is advised that keepers keep only a male-female pair or a group that is female heavy unless a large amount of space is provided.


Fleischmann’s Glass frogs will breed on leaves overhanging streams. They will lay clutches of about 35 eggs at a time.

Parents are fairly protective of their eggs and will sit near the egg clutch and fend off predators that try to eat the tadpoles and males will release bladder water onto the clutch to prevent desiccation.


Eggs take approximately 5-12 days to hatch, after which tadpoles will fall into the water below.


Tadpoles may need moving water to thrive as they are typically found in streams. They will readily eat a variety of fish foods including Josh’s Frogs Tree Frog tadpole food.

The tadpoles are known to partially bury themselves in the substrate for a time before becoming more visible later in development.

Natural Range

This species ranges from central Costa Rica, through Panama and the Pacific lowlands of western Colombia, south to Mata Real in Azuay Province in Ecuador. It has also been reported from the Department of Caldas in the middle Magdalena Valley, Colombia. It occurs below 400m. (IUCN)
