Just thought I'd get some hands-on advice in addition to my research: I currently have a glass-fronted, wooden vivarium which measures 18"h by 18"d by 36"w. I kept a paraguayan rainbow boa in there happily enough, but now it's empty I'd like to try something new.

My main reason for asking is that there is no fitting for a heat lamp in this viv - I kept the boa warm with a heat mat under the substrate connected to a 'stat. I know the majority of lizards need a constant light in addition to heat, and so I thought it best to ask here.

Not just after snakes, anything considered.
