A glass tank is better because it is heavier which mean more sturdier, glass tanks are harder to break then plastic ones,
Things you will need are
*bedding not pine or cedar
*food ask what food they are currently on and stick to that to avoid an upset stomach
*Water bottle, you can buy ones specially for tanks just ask,
*Tank glass is better
* a pair or more of mice , mice do better in pairs or more make sure they are from the same litter or cage
* a hideaway home
*Chew toys because mice are part of the rodent family which means their teeth constantly grows
I wish you the best of luck
