Hi. I'm new to the forum

I just bought my boyfriend two tree frogs for his birthday. BUT I have a question for anyone who can help??

We've had them in the terrarium for two days. The temperature and humidity are both fine. But they don't seem very active? Just wondering if this is unusual?

And we're not sure if they're eating the crickets or if the crickets are just hiding in the terraruim somewhere? Surely the frogs would hunt them if they were hungry?

I figured they might just be getting used to new surroundings, but owning frogs is totally new to us, so we're a bit worried (some might say paranoid ).

Any help would be much appreciated.
