I assume that you've removed it from the too moist location. Are there any healthy roots remaining? If so, you can try cutting back the dead roots to the healthy ones and repotting in a good, porous potting medium where it can receive the proper amount of moisture.

These plant can be easy to kill.

If you have them all in the same pot, then repot it separately so you can better control the water it receives.

Mine with the white veins was looking awesome last year but it didn't do well at all this winter. I just hope it recovers. In the meantime,the pink veined one has never been out of the terrarium I put it in to root,and it's doing just fine.

The ones with the really red veins are really something else. Totally have my eyes peeled for one of those!

Hope yours is recovering for you Angel. :)
