ive had my haplopelma lividurm for almost 3 weeks now and he has not burrowed yet. he will either stay in 1 place and not move or he will climb the tank. i have one of those small wood shelters for him and where i placed it i made a mediam sized hole in the substrate for him to start his burrow but he still hasnt. any one have any ideas? the only thing i can think of is stress because of a new enviroment but it has almost been 3 weeks so im not sure. any one have any ideas?
