I would like to know how big my first vivarium should be? I am intending to set up my first vivarium but I need to know what size vivarium would be Ideal for a baby corn snake. I would also like to know the cost if possible?
I am no expert on hatchlings Adam, but comparing the size you have mentioned and the size in the link Gmac has given you I would THINK that would be an ok size for a faun.
As for how long your hatchling would be in that size faun I am afraid no-one can give you a definite answer as all snakes grow at different rates. The general rule is that once the snake's length = the length + depth of its enclosure it needs to be upgraded.
Do have a look at the Setting Up A Hatchling Corn Snake - My 101 as Gmac has suggested....it really will answer most of your questions....and if, after reading it, you have any more questions then feel free to ask .
