Questions about cage size for adult gargoyle gecko
 

Am in the planning stage of getting a gargoyle gecko. I keep reading suggested adult cage sizes ranging from 18"Wx18"Dx18"H up to 24"Wx18D"x24H". After shopping for snake cages, those sizes sound small to me, though gargoyles are, of course, small in comparison to my colubrids. So I have a couple questions.

- If space & price weren't an issue, what would be an optimum cage size for a gargoyle? Right now my planned cage size is 24"Wx24D"x24H", but I could go larger if that would be better. Ex. 24"Wx124D"x36H" or 36"Wx24D"x24H" or 36"Wx24D"x36H"

- Is there a reason, other than space & budget limitations, for the smaller sizes? Like, do gargoyles naturally have a limited range?

Would appreciate input on this. I've no problem buying a bigger cage but want what is best for the gecko.
