Thinking of letting these go as a package deal. Maybe someone has set up a large tank and looking to fill up space? Not sure of the name of the Pectinia but it has beautiful peach highlights under blue. All are about the size of a human skull. You will have to drive to Sterling CO for pick up. 800.00 for all four hammer, Pectinia, Candy cane (one on the top), and Duncan. I need space.
