My Lithops otzeniana, a species I have always had my problems with, are doing just fine at the moment. They still live in my living room on the east facing window sill and they have just (almost) finished growing a new pair of leaves.
I am totally in love with their markings right now. They already look so beautifully like otzenianas.
