Just put the candy melts in a disposable piping bag and clip the tip off, then melt them in the microwave for 20 seconds, then knead the bag, 20 more seconds, knead, etc, until they're melted. Don't overheat it or you can really burn yourself. That would work for the fan coral.
This is another way to make other kinds of coral. If you do a variety it looks better! http://acaketorememberva.blogspot.com/search?q=coral
