That's pretty interesting that something sliced off a chunk of the Colt coral like a "frag
". I'm not sure if a Coral Banded could (would) do this - strange.
, Colt corals are one of the most difficult frags
to get to attach. I can almost guarantee you that superglue won't work with this coral. I've tried rubber bands, toothpicks, several different methods - only to have the Colt frag
floating off within a couple days.
One method that I *finally* had success with - plastic tie wraps/aka "cable ties" (zip ties).
I find with these, I can "snug" them down just enough so that the frag
doesn't escape the rock, but they don't tend to squeeze/cut through the coral like a rubber band does.
