My husband came home last night with what I'm thinking is a Cuban Tree Frog that was a stowaway in a fedex package from Miami. It is just under 2 inches long, so young. We got it a terrarium, a dish, hiding log, fake leaves, heating element, and crickets. I know they are nocturnal, but do they shut their eyes all the way when they sleep? I put crickets in yesterday evening. How do I know if the frog ate them or if they are hiding? Do the crickets sometimes burrow in the mulchey stuff you put on the bottom of the tank? I'm hoping that the poor thing is not too traumatized and will survive. Just looking for signs that he/she is ok. Any tips would be very appreciated!
