Care Sheet: Spotted Emerald Glass Frog (Hyla punctata)

Common Name: Spotted Emerald Glass Frog.

Scientific Name: Hyla punctata.

Distribution: Paraguay

Size: Males 30 - 40mm, females 35 - 45mm.

Sexing: The males of this species will make a loud quacking call, this is the most reliable way of sexing.

Colouration: The dorsal colouration can range from a bright green to dark reddish brown, this is marked with a mixture of cream, yellow and red spots. A dorsal line is also present in cream or red. This colouration can change considerably through out the day and what starts off, as a bright green frog with cream spots can suddenly become a dark red frog with yellow spots.

Requirements: These small agile frogs can jump over a large distance and so require a fairly large terrarium. A 15-gallon tank would be adequate for a group of 6 adults. They require a savannah type set-up with a substrate of bark chips, topsoil and moss. Furnishings such as logs, cork bark and sturdy thin leafed plants can be arranged to provide a number of climbing, perching and hiding places. A small water bowl (no deeper than the frog's height at rest) must be provided with clean de-chlorinated or spring water. The water will need to be changed daily to avoid the build up of ammonia and bacteria in the water whilst changing the water it is a good idea to visually inspect the tank and remove, clean and replace any soiled items. The tank will need to be heated to a daytime temperature of 26°C with a drop at night to 20°C this can be done with an under-tank heat-mat controlled by a thermostat. It is not advisable to use spot / heat lamps with amphibians and so a separate light source should be provided by the means of a fluorescent UVB tube. Once every two-three weeks the tank and its contents should be completely cleaned and sterilised using an amphibian / reptile friendly disinfectant.

Feeding: For adults a mixture of suitably sized insects including crickets, , flies, waxworm, small locust, caterpillars and moths should be fed every two-three days. A calcium and vitamin supplement should be used once a week. Young frogs will take hatchling crickets and fruitflies, these should be fed every day and a calcium and vitamin supplement used two-three times a week.
