I don't think anybody was ripping on him. The studies you asked for are pretty much field observations that state boas are solitary and do not live in groups. Russo, Rentfro and actual herpetologists like O'shea note their observations in the wild. Some exceptions include groups of thermo regulating boas and breeding broods. Male boas WILL fight over territory and a female. Your point is noted in captivity and I believe it can be done but with some added risk. Nothing bad may ever happen but in general most agree they are more comfortable alone. No disrespect to you or your point. Just did not want you to think anybody was being a killjoy because they said separate is more advisable. As you said do what works best for you and take notes.
