I would not house two males together, either. If you're having warmer weather in the northeast, it's a better idea to house them on separate Rubbermaid/Sterilite tubs of appropriate size. Although a hot spot is recommended for these guys, there are a few breeders here who only support ambient heat. I'd definitely also keep the newcomers quarantined (I personally do 90 days min). Also, I would not run any type of heating without a proper thermostat.
