Scientific Name: Hyla chrysoscelis.
Common Names: Cope's Grey Tree Frog, American Grey Tree Frog.
Distribution: North America.
Size: 1.25" - 2.5".
Sexing: The males of this species may be heard calling this is a fast trill. The males also tend to have darker skin on the throat and larger forelimbs. Females have a more rounded body shape.
Colouration: The dorsal surface is a light creamy grey to dark grey with darker almost black markings and banding on the limbs. Orange flash colours are present on the inside of the limbs.
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 well-planted woodland type set-up with a substrate of bark chips, topsoil or moss. Furnishings such as logs, cork bark and sturdy 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 tank will need to be heated to a daytime temperature of 24°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.
Maintenance: Water will need changing daily to avoid the build up of ammonia and bacteria. Whilst changing the water it is a good idea to spot clean the tank and remove, clean, and replace any soiled items. At least once a month the entire terrarium and it's contents should be striped, cleaned, and sterilized using an amphibian friendly disinfectant.
Feeding: For adults a mixture of suitably sized insects including crickets, mini-mealworm, flies, waxworm, small locust, caterpillars and moths should be fed every two-three days. A calcium and vitamin supplement should be used once weekly. 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.
