In a few weeks my monitor is finally getting his brand new custom built 8x4 viv as his new residence - therefore I am going to have an empty 4x2x2 (twitch, twitch) and I am wondering what to put in it.

I quite fancy either an ackie or some type of tortoise - but not a big one as I would like one that would stay small enough to be happy in a 4x2x2. Would just one ackie be happy in a 4x2x2 (Marshall?) or could anyone recommend a nice tortoise that stays small and doesn't need a massive viv (I love the redfoots but they need 8x4s!!!)

Or is it too small for either of these things? All suggestions welcomed
