Well I have had my baby white's tree frogs 4 days. But for the last two days, I have not seen them in the terrarium. They cannot get out and the doors have only been opened when i look through the plants to find them. I have removed everything that I can. The only thing left is the background, waterfall and plants. I looked under the leaves of all of them and behind the background but I still can't find them. I can't lift the waterfall out, I can only check the water and nobody is in there. I have found a few crickets. But I can't find them. Should I dig out the waterfall and look under it, or just continue to put food in there?
