Don't panic - I've killed plenty of these (mostly through drying out). If you
ever get one to flower, you'll have more D. capensis's coming up than you know
what to do with... ;-)

This could be a combination of sudden change in light & particularly humidity.
Always try to "harden off" plants by gradually removing the plastic bag, in the
case of humidity, increasing the light etc. so that they have a chance to adapt
to the new conditions.

Older capensis's tend to from these bare, long woody stems. One approach to
the problem is to hack of the plant at just below groundlevel (if you have
spares...) and let it grow back from the roots, which it does happily.

Check for aphids or similar pests, if you haven't already done so - these can
cause this sort of growth. Another possibility is that the plants are
suffering from transplant shock or sudden change in conditions (maybe) or
simply lack of water. You could try putting a plastic bag over the plant(s)
which may help, but these plants are fairly hardy and will grow back from the
roots if the rosette section dies off.

Good luck
