Is it ok to keep a blue tongued skink in a 60x45x45 tank or I had better buy a 90x45x45 one? Will an adult skink feel comfortable in the smaller one?

The first one is more convenient for me and hopefully my husband won't disagree much.
if you decide to keep a pet please think about it as a living creature first of all and buy a NORMAL size tank which is 90x45x45. how would you feel locked in a tiny room?
