The other is a ghost color(natural) but,its getting rotten spots
Shannon ~ if I had to guess, I'd bet it is from being kept too damp and/or too cool conditions.
These need very little water when they are dormant. I think I would try to save it by removing it from the pot and lay the pieces of plants out to dry thoroughly. Then I'd repot and water sparingly till springtime and the new growth starts. Good luck ~ Kristi
