Andrew --- I had good success transplating A. cervicornis pieces (~5cm long) on the Caribbean coast of Panama by inserting one end of a coral piece into soft Tygon tubing. The tubing piece was about 5 - 10 cm long, with a diameter that formed a tight fit on the coral. There are many ways to anchor the other end of the Tygon tubing to
something fixed (e.g., a spike, rebar, etc., driven into the reef). Heavy-duty, all plastic, uv-resistant, cable-ties work very well for this. Because of crevice corrosion, do not use the cable ties with metal inserts, stainless or not.
Transplants were more successful if elevated above the surrounding substratum. Hermodice ("fire worm") attacked the segments placed at substratum level. The coral tissue quickly grew over the Tygon tubing.

I'm expecting partial attachment to the reef within 2-3 weeks and overgrowth of the nail within 5-7 weeks. Will nail rusting inhibit overgrowth?
