i've got a leopard tortoise... and before that i had a redfoot.
it depends on the size you want.
there are smaller species and larger ones.
tropical species like red foots need high humidity and a moist veggie/fruit diet with a moderate protein intake.
desert/dry habitat species like leopards and sulcatas don't like excessive humidity and prefer more of a grassy diet with low protein intake.
consider what you're goign to house it in before jumping in on it.
