I'm a newbie. I have a green tree frog had for about two weeks. I have him in an Exo-terra 30x30x45 terrarium with a coconut fiber substrate. However, since yesterday, the GTF has dug himself a hole in the coconut fiber and won’t come out. Since I've had him, has been in the absolute top of the terrarium. Now all of a sudden has buried in a hole. Has anyone seen this before?
Regards,
BRAD
