welcome to the forum! i have mine in a 3ft viv which is ideal for a corn. the viv should be half the length the corn will be so they have space. what type of corn is it your looking at getting?
heya and welcome most adults will easily get to the 4ft mark so a 3ft viv is a minimum requirement for an adult corn. when they're small the appreciate a small space though or they can get stressy.
