Most of this has to do with the shipping required to get livestock from thousands of miles away to your LFS. Gas prices will never be low again so prices, for exotic stuff like this especially, will continue to rise.
Don't let that fool you though, yes it's true, but every middleman on the way is lining their pockets a bit also. Te pizzeria in my town raised the prices of their pizzas by 3 dollars in the past 2 years due to gas prices, and posted a note on their signs saying this. Hypothetically, let's say they make 5000 pizzas out of a shipment( I have no idea of its more or less) before they need to reorder. You're telling me that it costs 15000 dollars more in gas to get the ingredients?
Simone selling coral should be affected even less, since they frag off of mother colonies an very rarely bring in shipments of stuff such as Xenia, zoas, and most other softies.
