a few questions... is she a loner? too many in one tank??

[Egapal]

My sister currently has three BP's and two corn snakes all in the same tank, and has had them all together for almost three years with no problems. She started with two then three in the 20 gallon, then 4 in the 20 gallon. now that the corns and the one BP are pretty big in size her husband built her a 5'x3' tank that still houses them all with no problem. Another family member has aa 40 gallon tank with one large BP (almost 4 feet) and a smaller one probaly 20-25" long in the same tank as well. again with no problems.

My brother shoots up heroin. Doesn't mean its a good plan for you or I. It is your snake and at the end of the day you can do what you want with it. If they were my snakes I would have one per enclosure, for all the reasons already mentioned many times on this forum.
