Got both that you suggested, I had one with an overgrown beak, I was going to wait until she tamed up a bit before I tackled that beak, however feeding her on a stone plate and providing cuttlefish seems to have corrected it.A piece of flagstone within your set up ....using it as a "service plate" will help out. Also try and keep a piece of cuttlebone within the enclosure at all times as well.This will provide your tort with calcium intake as well as honing the beak.
