Hey everyone, I just got three red-eyed tree frogs three weeks ago. One of them died about five days ago and the other two are lying on the ground with all four limbs completely stretched out. I called the pet store and they didn't know what it was, only that it must be something environmental since all of them are succumbing. Does anyone have any idea what is happening? They were completely fine until about five days ago, when one of them disappeared (later found dead), and a second one turned a very dark green color and starting sleeping on the ground. Today, the two remaining ones are both on the ground, both light green, both with their legs stretched completely out behind them. I mist them 2-3 times a day and turn on a space heater near the tank whenever it gets below 70F inside. They have plenty of crickets to eat (I don't think they've been eating for a couple days). They are also awake right now while they lie on the ground, when normally they would be asleep up on a leaf or on the glass. I feel so terrible and I have no idea what I have done wrong!
