Thanks for all your help with these guys. I have considered adding the small space heater already and think that I will probably do that. Before I do if I turn off the strong spot and leave my other spot on that is around 80 degrees, my ambient will probably drop to about 67 or so. Do you think that is OK? I will switch out substrate and go with a potting soil and peat mix that is what I have seen described in a few places. My last question is about the feeding bowls, do you break the legs off the crickets, or do they just kinda stay in the bowl? Again, thank you very much for all your help.
