With those kind of softies, I would see it as an opportunity to keep some cool 'coral-risky' fish in an attractive lush tank. The 265 gallon volume would mean you could keep some nice angels and butterfly fish. There are two tanks that have a lasting memory for me: 1 was a large tank covered in sinularia housing some holocanthus angels, and one was a softy tank with some nice butterflyfish. The other thing I would add is that my sinularia and leathers seem to handle mushroom crowding fine, so you could add some of those for some variety.
