depends on your snakes origin but mostly kind of form and moisty and nice an humid
a 1 meter and a half vivarium will do good for a milk snake
About 22-24 degrees celcius I think
baby corn snake are timid it is their nature and it is a good sign as long as they are babies. if you have an adult corn snake you should not have this problem.
A Vivarium -The latin meaning is "place of life".See link for more info.
Perhaps it's not hungry - or it's shedding - or the temperature of the vivarium is wrong.
It depends on the size of the snake. The vivarium should be at last half the adult snakes length. on its longest side - and a quarter of the adult snakes length for the measurement front to back.
No - Corn snakes can grow to 72 inches in length. The minimum size vivarium at that size would need to be 48 x 24 x 24 inches !
Assuming you're referring to an artificial enclosure - it's a vivarium.
Age has nothing to do with it, size is the determining factor and it has a lot to do with the original size of the enclosure in the first place and the size of the snake contained in it.
It will regurgitate it (be sick). If this happens - it's usually a sign that the vivarium isn't warm enough.
a 1 meter vivarium will be right for a corn snake
It could be a number of things. Changes in temperature or humidity in its vivarium. Introduction of another snake into the enclosure. Time of year (some snakes refuse food during winter months). Even moving the vivarium to another room could put a snake off feeding. They're more sensitive to their environment than we give them credit for.
