Name: Rhacophorus reinwardtii is commonly called the Black-Webbed Flying Frog in the hobby. Occasionally, Rhacophorus reinwardtii is referred to as the Reinwardt's Gliding Frog.

Recommended Vivarium Size & Setup: Housing captive bred Black-Webbed Flying frogs will require at least a 20 gallon or 18x18x24 front opening enclosure. A tank this size could house about 3-4 adult frogs.

Substrate for these frogs could be tackled from two different directions: naturalistic and artificial. The naturalistic route will allow for live plants and microfauna to thrive. Tropical BioBedding is the best bioactive substrate Josh’s frogs has to offer for plant growth and microfauna. This combined with sphagnum moss and leaf litter on top will keep your tank humid enough for this species of frog.

The artificial route involves Josh’s Frogs Frog Foam terrarium liner. This will act as a reservoir for moisture in the tank and allow for easy cleaning regularly.

You will want to provide your Black-Webbed Flying Frog a small water source that they can soak in at night. Most of the time your frog will be perched on the glass or the décor in their enclosure.

These frogs should be provided with a tropical level of UVB as they are mostly arboreal. Please keep in mind that wild caught gliding frogs tend to require much larger enclosures to thrive, and even then may easily injure themselves as they jump around at night. Josh's Frogs strongly recommends seeking out captive bred animals.

Temperature: Rhacophorus reinwardtii ideally are kept at about room temperature, in the low to mid 70s. Like many other tree frogs they can tolerate short bouts of temperature spikes into the low 80s but keep in mind this is a montane species that typically likes it cooler. Make sure to keep an eye on temperatures with a digital thermometer.

Humidity: Rhacophorus reinwardtii can handle a wide range of humidity levels, but prefer a humidity level of 60-80%. Routine spraying and a full screen top will aid in providing proper humidity levels. Be sure to provide a shallow water dish so that your Black-Webbed Gliders will not dry out in lower humidity. Make sure to measure humidity with a digital hygrometer.

We love the Exo Terra Digital Thermo-Hygrometer Combometer to monitor both temperature and humidity!

Size: Adult Rhacophorus reinwardtii are medium-sized, and there is a small size difference between males and females. An adult male may reach about 2.5 inches. Females will be a bit larger and bulkier than a male, and measure just over 3 inches. Juvenile Black-Webbed gliders will be about 1 inch long when they are sold at Josh’s Frogs.

Age: There is not any good data surrounding the average lifespan of Rhacophorus reinwardtii, but like most other tree frogs they will most likely live for up to 5 years and probably longer with ideal care.

Feeding: Rhacophorus reinwardtii are capable of eating crickets of varying sizes their whole lives, starting at 1/8" and ending with 1" crickets at adulthood. Their diet can be supplemented with small dubia roaches, black soldier fly larvae, and the occasional waxworm (as a treat).

At Josh’s Frogs, we feed our Black-Webbed Gliders primarily 1/4" crickets at the time of sale.

Sexing: Sexing adult Rhacophorus reinwardtii can be fairly straightforward once they’re older, but can be difficult on younger animals. Once the frogs are about 12-14 months old, they display obvious sexual dimorphism. Females are about 2% larger than males, and much more rotund with eggs visible when they are developed. Males are smaller, more slender, and typically call when kept in a wet or more humid environment. At this stage nuptial pads will also start to become visible in male frogs.

Color/Pattern: Rhacophorus reinwardtii are a jade green color with a prominent black webbing between the toes on all four legs. They have a cutaneous square shaped protrusion near the cloaca as adults.

Social Behavior: As with most frogs, Rhacophorus reinwardtii will be mostly solitary but can be kept in small groups with little aggression being displayed outside of the breeding season.

Breeding: Rhacophorus reinwardtii is a foam nest breeding frog and will affix a mucousy foam on the undersides of branches and leaves overhanging water. These frogs require cycling and a rain chamber to breed, much like other tropical tree frogs.

Natural Range: This species has been recorded from the foothills and mountains of the Main Range of Peninsular Malaysia at 250-1,100 m above sea level, extending to Borneo and Indonesia (Taylor, 1962 and Berry, 1975).
