I just got a crested gecko about a week or 2 ago. i have 3 questions, so far, haha. First, i was wondering if they bite, and if it hurts. Mine hasnt tried to bite or anything, its been really sweet but i was just curious. second, mine has a coupple small white bumps, mostly between his back legs, is that normal? and third, he is normally a green color, but today hes been this greyish purple kinda color, but the end of his nose is still the normal color he ussually is. any help would be awesome!
