my ideal dream terrarium would be huge enough to fit a cutaway termite mound so i can peep inside. outside would be African landscape. like this:
and it would be bioactive.
IMO BP's in T8's (48x24x12 pvc enclosures) are spoiled. lol i'm actually assembling something similar. i would include at 2 hides, wood substrate, fake foilage, something to climb and a water dish big enough to soak in. this is ideal and a step up from the tubs most of my BP's are in. a 40gallon tank is more than adequate for the life of a BP if u choose the glass terrarium route and i actually think then can be fine in a 20 gallon if u don't stuff it all the extras.
