Asian Greenback Frog (Rana erythraea)
A.K.A. Asian Emerald Frog, Cascade Frog
Asian Greenbacks are small green frogs with brown, yellow, and cream-colored stripes down their backs. Males grow to about 1¼-2 inches in length and have thinner bodies than females. Females grow 2-3 inches long and have stouter, rounder bodies. They are nocturnal and males will sometimes chirp at night. They live about 5 years, but have been known to live up to 10.
Habitat and Tank Requirements:
This species is native to the jungles of Southeast Asia. They do well with plenty of live plants and other things for them to climb, such as wood and rocks. Approximately 1/3 to 1/2 of their tank should be water. You can either use an under-gravel filtration system or clean the water every 2-3 days. Use common sense when choosing a filter: a pump that is too small will leave the water dirty, while a too-powerful pump with filter out the microorganisms needed to maintain a healthy pH.
Be sure there are no openings in the tank through which the frog can escape. A hole large enough for a frog to stick its head out of is large enough for it to escape.
Greenbacks are small enough that you can keep 3 or 4 in a 10 gallon tank, however, as with all frogs, do not keep different species of frogs in the same tank. There is a risk of disease and parasites being spread between species, even if the carrier frog does not show any symptoms.
The comfortable temperature range for these frogs is 70-75º F during the day and a slight drop to around 65º F at night. LEDs or other low-wattage light bulbs work best for maintaining these temperatures.
Asian Greenbacks are insectivorous and will feed on small crickets, fruit flies, mealworms, wax worms, and any other insect small enough for them to ingest. You can also feed them freeze-dried foods such as blood worms and brine shrimp, turtle or amphibian pellets, and even tropical fish flakes. It is recommended that food be dusted with calcium to prevent bone softening.
Allow your frog time to become accustomed to its new home before handling them extensively. Handling them little by little over a period of time lets the animal get used to you and reduces stress.
