The first corals in the tank were hitchhiking cladocora, phyllangia and siderastrea. Once I convinced myself that I could keep them alive, I traded some baby cichlids for a toadstool leather. Years down the line, a larger tank, and several fraggings later, it still has a prominent place. It came with a chunk of a stony coral at the base, which has grown into a nic green, and still unidentified, encrusting coral.
