I've had gorgonians here and there.
The cool thing is their growth behavior.
When mine was fragged in half, it closed its polyps during the time it took to heal.
Since I'm experimental with my tank (not recommended for anyone who is new to reef battles that come with) I have experienced a few issues with the gorgonian.
1)tissue damage- certain animals or rock have damaged the flesh on my gorg, exposing its skeleton. Some times it would happen mid branch. Other times there would be a chunk in the main stalk.
The fastest way I have gotten it to heal was by clipping the branch right before the torn flesh.this gives the coral much less distance to heal fully.
If the main stalk has flesh torn just leave it be, unless it is near the base and you can clip it off the base to reattach to something else.
What's left over as a stump will grow back, the freshly cut gorg will reheal. Any branch you cut can also be attached to a plug and left to heal.
Gorgs are definitely fragile but hardy too, given good water quality and food
