The eastern gray tree frog is a small arboreal frog that is located in the south easter part of north america. It's gray skin often puts it behind other flashier species, but it's personality, hardiness, and bird-like calls make it a personal favorite with many.
Tank and Setup
H. veriscolor and H. chrysoscelis like to be as high up in the tank as possible, often climbing up to the lid of the tank on the walls or hanging upside down from the lid itself if they can. So I recommend at least a 10gal. tank for 1-8 of these guys and plenty of things to climb on.
The substrate should be coco fiber or something that will hold moisture/humidity and allow the frogs to bury themselves if they feel like it. I have noticed mine burrowing durring low temps or winterizing. They don't need it very deep though. A good size shallow bowl is good for soaking in. Just be sure to not make it too deep and change it when it begins to look dirty.
As far as things to climb on, mine like pothos and some bamboo shoots to climb on in addition to the walls of the tank.
Temps and Humidity
Gray tree frogs can tolerate a broad range of temps, but it is optimal to have them no lower than 60 at night and no higher than 85 in the day, though they can and will tolerate temps both higher and lower than that range. Also, they do not need a very high humidity, but do enjoy a misting once a day or once every other day.
Much like L. caerulea, the White's tree frog, gray tree frogs will eat most things that are small enough to fit in their mouth. They are not shy and are voracious eatters of crickets, meal worms, fruit flies, and any other unlucky insect that happens to fit into their maw. Though a main diet of crickets is recommended, it can be varied with meal worms, earth worms, "lawn plankton" (with risk of parasites), and other small to medium feeder insects.
Gray tree frogs breed in the "usual way" by depositing their eggs into standing pools of water during the months of April to May in their natural habitat.
The male serenades the female with a shrill call that sounds very much like a very loud cricket. As masses of these frogs gather around water sources, the sound can grow deafening.
After amplexus, the female lays a mass of eggs in the water which the male fertilizes.
Within a few days the tadpole developes and will break through the casing of the egg to swim freely in the water. They use fallen leaves and sediment on the bottom of the pool/stream/puddle/pond to hide from predators.
Lowering water levels prompts the tadpoles to morph after about 6-8 weeks into froglets about 3/8 inch long.
Care for Froglets
Froglets need to be fed pinhead crickets and/or fruitflies every day until they are at least 1/2 inch long or longer, then the feeder insects can get bigger as their mouth is bigger. Anything that fits easily will go in. Fruitflies are not a very good staple but they can fill in the gaps between crickets.
Be sure that any water source is well maintained. Dirty water can kill and so can water that is too deep. But regardless, the froglets need both a water dish and frequent misting as it is easy for these little guys to dry up when they are this young.
When young they can be housed together in quite large groups and seem to like the company and cluster on large leaves together under the heat lights, but as they get older they will need more space because most adult gray tree frogs mark out a small place as "theirs" at least until they get tired of it and find another place to call their own, such as a particular leaf, corner, log, bowl, rock, etc.
