That is why I am asking. If a tub is no good I am obviously not going to put one in there. And if I can't provide proper housing I am not going to get one period.
Is a 36x18x17.5 appropriate or do I need to go to a 4ft long one?
you could do 36 but most likely you would end up with a cramped snake. 4ft seems more suitable. Your gonna want a good amount of floor space as well though..
