Toadstool is 23" round I need the space is there a way to reshape it with rocks on the underside to make it grow more upward so I can utilize the space under for coral that do not need direct light? Also is there a market for a coral this large? I donated my last one 28" to The Atlanta Aquarium but they would not give me one free pass to see it after it was settled in, so I did give it to them. Happy 4th to all
