Hi everyone. Long time reader, first time poster
I have a small terrarium set up that is home to a few adult whistling tree frogs and some Southern and Golden Bell frog babies. In the last few weeks i have had two of my three whistlers die and three of the other die. I noticed a couple of them went off their food and had trouble moving shortly before they died. I have had the tank set up for about 6 months now without any previous problems. Could there be an infection/fungus spreading through the tank and is there anything I can do about it?
