I have been raising gray tree frog tadpoles for a while now, and a couple days ago two morphed into frogs. They still had small tail stubs, and I moved them into a terrarium with only a little water bowl and lots of climbing areas. I went to check on them the next day, and both frogs were dead on the floor. I am very concerned because two more of my taddies are turning into little frogs. Please help! What do I do? What did I do wrong?!!
