When I first got my cresties, I paid much dinero for a male that had a sweet tail stripe...Within 15 minutes of him being home, when I transferred him to his cage he dropped his tail.....and there went the sweet stripe...lol...he is fine and climbs like he never had a tail....so it is not a big concern if the cresties have no tail....they should be less expensive (see I didn't say cheaper...animals arent cheap) also!
