I like your x-mas cactus. It looks like you have two cactus, one pink and one red. I have a red one that is 3 ft across and one bloom has just opened. Mine is on the east side of apt., so only gets morning sun. I cut it back last spring, but it has a mind of it's own and is now as big as it was before I pruned it. Can not tell you how many starts I have given to friends whom viewed it.
