Congratulations on getting your new critter. I have a few T-10s and use RHPs as the sole heat source in all of them. There’s no need for the heat tape imo. I can achieve a good basking spot and ambient temps with just the RHP even during the winter months. I use 60qt tubs for my baby snakes. I like tubs that have latches on each end.
