I’ve had my crested gecko almost a year now, and about 3 days ago I put him into his new vivarium tank that I set up, no food has been eaten, and we haven’t seen him come out at all. I’ve gotten up several times throughout the night to check and still not coming out. There’s a log he can hide in, but there’s no way for me to see if he’s in there since it’s attached to the wall. I’m just worried that maybe he died, or got out but neither of those are very likely. When should I be concerned?
