Hi I have a small problem.

I am a new tree frog owner. I just got 6 tiny babies on Saturday. They are all 1/2 and inch to 1 inch. Their home is doing great. Temp and humidity are good.

My problem is I can't find them. I am almost positive they are in there. I was careful when I opened the shipping containers. I know I saw the frogs go in. I have a good top and I keep a rock on it just to be sure it does not come off. The crickets I have fed them have disapeared.

I am worried. If I can't find them, how do I know they are ok? When I clean their home, how do I find them to make sure the stay in their home and don't get out?

I even have have a blue night light. I know they are nocturnal. But I have seen no movement at night.
