Hi Lynn, thank you for the reply! I'll set up a more austere quarantine tank when I get home, and I'll give them an infrared heat lamp. So I should probably mention I found a gross jelly like blob in their water dish after the first night. Both frogs seem healthy, but now I'm concerned... I didn't take a photo, but it was small and kind of clear, with a dark irregular center. About the size of a standard six sided die. Does this sound like parasites? Both frogs seem to be changing color as they move around, and they discovered how to hide from the light and are hiding there. That's unfortunate about the moss, it really does look quite nice and it is fairly well established in the tank, but I suppose I can order captive cultured moss easily enough. Thanks again!
