use it for fish!!!! you can have lots of different kinds and theyre far more active! well.. constantly!!
if you were going to put a snake in there i would try and get one whos fully grown.... i mean a hatchling corn wouldnt be able to live in a 48" tank.... u'd never see it! if you have rescue centers near you, go take a look, if something tickles your fancy find out if you have what it takes and go for it!
good luck! hope you make the right decision!
oh yes! i may be wierd... but this wierdo comes with new, improved Live Journal
