East Tx,
If you plan on glueing a gorgonian, to ensure survival of the glued piece, do the following:
1. cut the length of gorgonian you want + about 3/4 - 1".
2. clean the "meaty" part away at the bottom from the bottom where you plan on glueing it.(the 3/4 -1" section)
3. having drilled, or made a small hole in the rock, insert the glue, then insert the gorgonian making sure you have no glue touching the meaty part of the gorgonian.
You can also put the gorgonian in the hole, and stuff a small piece of styrofoam in it to hold the gorgonian in place (better pack it tight, this is what will hold the gorgonian when fully grown). Once the glue dries, the meaty part of the gorgonian will grow over the dried glue. You can use super glue gel.
