I have been given a frag of a leather finger. it's fairly large cutting (around 3" sq. It came from a monster of a coral that was doing very well. I have banded this frag onto a piece of LR but it's not looking good. The fingers seem very limp and are hanging over the edge of the rock. It still has its color but very few polyps are on display. It has been in my tank for two weeks but has failed to bond to the LR. I have a xenia and cauliflower that are all doing well. Any ideas on how to improve the health of this frag. Is the elastic band causing distress?
