Bought a Nicaraguan boa....

[Bogertophis]

Thank you! Right now the only problem I have is he won’t use his hide, he wedges himself between the hide and the tank. The breeder had him in a tub with no hide so I don’t think he really realizes what it’s for. This is just the first day of ownership so maybe he will catch on.

I wouldn't worry about it...it's as you said, all new to him. When you get around to handling him, if he hasn't figured it out by then, when you go to put him back in just
aim his face toward the hide's doorway & most likely he'll catch right on & go in. Can't remember a snake that could resist a dark cave to go into.
