If I understand correctly, your tank is about 6 weeks old. Certainly your call, but before I would buy any expensive coral, I would wait until less expensive coral as well as fish survived 6 months or even longer. Some water issues affect both fish and coral. Then, a lot of other water as well as issues such as light affect coral. Some coral may look ok for a while, but then a slow death follows. I went through a lot of less expensive, supposedly easy to maintain, coral frags before my tank stabilized enough to support and grow coral.
