I have a green capnella leather coral that has been dropping a few branches every couple of weeks. However, I cannot get them to attach to the rocks or frag plugs in my tank. I've tried drying them off and gluing them but that seems to kill the coral. I've also tried tying them to the frag plug with rubber bands, but that seems to split them in half leaving me with two smaller branches that are even harder to find when they fall off. Out of the dozen branches that have dropped so far, I was only able to get four of them to attach, and the others either died or are currently floating around the tank. Can anyone give me some advice for attaching them?
